The main display interface focuses on the emergency user by putting information important to the user up front. Hands free, the first highest priority event is shown. The display always gives the last highest priority event. Arriving at the panel and without opening the door the first and last alarm is given. Simple to understand lights and switches help the emer-gency user execute system commands with confidence.A menu system supports maintenance functions such as disables or reports for use by staff or service personnel.Standard Features• Uses simple lights and switches • Displays information important to user • Hands free first alarm display• Last event of highest priority always displays • Eight lines by 21 character graphic LCD display — 168 characters total • MultlingualSupports English, French, Spanish, and Russian • Uses queues to sort eventsA queue is a list of messages Alarm, Supervisory, Trouble and Monitor • Slide in LED and switch labelsMakes customization for regional language easySLiquid Crystal Display Module3-LCD0186APPROVEDEN 54-2: 1997 + A1: 2006EN 54-4: 1997 + A1: 2002 + A2: 2006EN 54-16: 2008Page 2 of 4 D A T A S H E E TE85010-0071Not to be used for installation purposes. Issue 1.1ApplicationThe 3-LCD module mounts to the local rail over the nodes Central Processing Unit Module (3-CPU). The 3-LCD module is optional in any network node.Ensuring information clarity the 3-LCD uses a backlit high contrast supertwist graphical display. Eight lines of 21 characters provide the room needed to convey emergency information in a useful format.The 3-LCD always displays the last highest priority event even when the user is viewing other message queues. Further message flexibility is provided with EST3’s message routing ability. Messag-es from a node can display at every node on the network or mes-sages can route to specific nodes only. Routing can be initiated at a specific time/shift change. There is no need to have messages display in areas that are not affected by an event.The 3-LCD can display messages in English, Spanish, French, and Russian. The bilingual display lets the operator select between either of two languages. Consult your representative for available language combinations.The EST3 system configures for Proprietary, Local or EN54 market operations. The mode of operation is selected through the System Definition Utility (SDU) which may adjust the following operations slightly to fit the system operation selected.LEDs and SwitchesFurther enhancing the 3-LCD user interface are easy to read and understand lights and switches. All functions are laid out in a logi-cal order. At the top of the 3-LCD are five system status LEDs. Here determining the general condition of the system is easy.Power LED : Green, on when AC power is on.Test LED : Yellow, on when any portion of the system (Group) isunder test.CPU Fail LED : Yellow, on when CPU stops running.Gnd Fault LED : Yellow, on when a ground exists on the system (group)Disable LED : Yellow, on when any point or zone is disabled by a user.Below the general status LEDs are located four, LED / Switch common controls. The versatility of EST3 allows system design-ers to define the features as affecting a domain (defined group of nodes) or as global (affects all nodes) across the network. This feature is very useful when configuring systems with multiple build-ings on one network. As an example, operating the reset in one building may have adverse effect in other buildings. With EST3 having operational differences between buildings on the same network is not a problem.Pressing Reset starts the system’s reset operation. The yellow LED has three flash rates during reset. The LED flashes fast during the smoke power down phase of reset, flashes slow during the re-start phase, and turns on steady for the restoral phase. The Reset LED turns off when the system is normal.Pressing Alarm Silence turns off all Notification Appliance Circuits defined as audible. The yellow LED turns on when silence is activevia the Alarm Silence switch or via alarm silence software timers.Pressing Panel Silence turns off the system’s internal audible signal. The yellow LED turns on when panel silence is active. The EST3 panel buzzer has user programmable signal rates for alarm, supervisory, trouble and monitor conditions.Pressing Drill turns on the drill LED and all signals sound evacua-tion. Drill does not activate city tie connections. Auxiliary relays willnot activate unless programmed to do so with drill.Liquid Crystal Display. In the normal condition the date and time plus a definable system title display on the LCD. The last line of the display gives an alarm history. This total equals the number oftimes the system has entered the alarm state from the normal state.When active events are on display, the LCD formats into fourlogical windows.In the system status window, the display shows the time and the status of active and disabled points.The current event window, lines 2, 3, 4 automatically display the first active event of the highest priority if the user has not taken control of the system. Once the emergency user takes control, thiswindow displays user message selections.The second line of the display shows system event information. Inthe example above the display shows the chronological number of the event (0001 is the first alarm) followed by the event type (Alarm Active). EST3 supports over 45 event type messages from which system designers choose. The last two lines of the current event window are custom programmable location message lines with space for 42 characters.The last event window shows the last highest priority event. This window is always displayed and updated automatically by the sys-tem. Here the emergency user can monitor the progress of a fire.system viewing the second alarm message iseasy, just press the NEXT key. The nextmessage scrolls into the current event window. The last highest priority event always remainson view. No matter what queue the user selects for viewing, the LCD always displays the most recent alarm. A new alarm event resounds the panel audible signal and appears immediately on display without overwriting information the user selected for view.The final window of the LCD the type status window shows the total number of active events by queue type. A is alarm, S is supervisory, T is trouble, and M is monitor. The number following each letter is the number of active events existing in each queue.EST3 breaks down event types into queues and automatically displays the first event of the highest priority type.Page 3 of 4 D A T A S H E E TE85010-0071Not to be used for installation purposes. Issue 1.1EN54 ComplianceEST3 has passed the British-based Loss Prevention Certification Board (LPCB) certified EST3 control panels and power supplies as having surpassed the requirements of the pivotal EN54 standard, parts two and four as well as part 16. LPCB Certificate #262ab In order to meet these standards, display and control functions have undergone slight modifications for the EN54 marketplace. These differences are highlighted below. All other control and annunciation features remain unchanged.Note: EN 54-2: 1997 + A1: 2006, EN 54-4: 1997 + A1: 2002 + A2: 2006, and EN 54-16: 2008.System Status LEDsPower LED (Green): on when DC power is on.Test LED (Yellow): on when any portion of the system (Group) is under test.CPU Fault LED (Yellow): on when CPU stops running (processor failures must be manually reset).Gnd Fault LED: Not available.Sounder LED (Yellow):flashing indicates fault on sounder circuit. Steady indicates a disabled sounder circuit.Disable LED (Yellow): on when any point or zone is disabled by a user (disabled conditions have priority over fault conditions).Switch FunctionsPressing Sounder On/Off turns off all sounder circuits defined asaudible. The yellow LED turns on when silence is activated via the Sounder On/Off or via the alarm silence software timers.See Page 2 for descriptions of Reset, Panel Silence, and Drill func-tions.Event QueuesFor EN54 compliance, EST3 configures for remote proprietary system operation. This requires that every event must be acknowl-edged by viewing them before the internal buzzer will silence. Thepriority order is Fire, Fault, Disable, Monitor.Priority order is alarm, supervisory, trouble, monitor. By usingqueues an emergency user does not waste time scrolling through a mixed event list looking for alarms or confusing an alarm mes-sage with other message types.EST3 configures for Remote proprietary system operation where every event must be acknowledged by viewing them before the internal buzzer will silence. Or the EST3 will configure for Local operation. Here the internal buzzer silences by pressing panel silence. If any events exist in queues that have not been viewedthe queue LED continues to flash informing the user of un-seen events.When all events in a queue are acknowledged or ‘seen’, theLED associated with the queue turns on steady. If a new event is added to the queue, the EST3 internal buzzer resounds and the queue LED flashes.EST3 allows device grouping into logical group zones. Here two or more alarm devices (such as detectors or pull stations) make up the zone. When a device in the zone activates, the LCD displays the zone description. Each zone only displays once, regardless of the number of devices active within the zone.DetailsTo display device information the user presses the Details key. The device with the lowestaddress displays in the first window.If multiple devices are active each is available for viewing by using the arrow associated with the Previous Message Next key andscrolling through the device list.expand beyond the Main Display interface by adding a Control Display Module and assigning features to its switch controls.For Maintenance users, the EST3 provides a smooth operatingmenu system providing powerful tools for system management, reports, and trouble shooting.Installation and MountingLIFE SAFETY & INCIDENT MANAGEMENTContact usPhone: 800-655-4497 (Option 4) Email: ************************ Website: 8985 Town Center PkwyBradenton, FL 34202© 2020 CarrierAll rights reserved.Engineering SpecificationThe system shall provide a user interface that displays system events in a text format, and supports basic common control LEDs and switches.

Application Note 497LCD Controller Using MAX II CPLDs IntroductionThis document details the implementation of an LCD controller in an Altera ® MAX ® II CPLD. The example display uses an Optrex 16x 2 Dot Matrix LCD module, such as the popular SC1602D device. The controller receives its display signal from a microprocessor or a micro controller and translates it into commands that are understood by the LCD module. MAX II devices possess the industry’s only user flash memory (UFM), which is used by the controller to display a message upon power on. This eliminates the need for an external memory. Also, no external clock signal is required by the controller as it utilizes the CPLD’s internal UFM oscillator for its clocking needs. These unique features make the MAX II CPLD the perfect target device for such a controller.LCDsLiquid crystal displays (LCDs) are thin, flat display devices made up of any number of color or monochrome pixels arranged in front of a light source or reflector. These displays have become an indispensable part of most of electronic devices. Some features that have made LCDs popular are:■LCDs provide applications with a useful interface that allows debugging capabilities and provides the application with a more professional look ■LCDs use very small amounts of electric power; they are very suitable for battery powered devices ■LCDs are slim and use small amounts of space compared to other display types Most LCD modules are equipped with a generic interface, on-board controllers, and an on-board driver. Thus, using an LCD to enhance the visual appeal of any application has become a lot simpler. Some devices that use LCD displays are wrist watches, calculators, laptops, PDAs, cellular phones, home electronics, and toys.LCD ControllerYou can easily integrate this controller design into any application to provide a suitable display unit. It meets the timing constraints of the LCD by generating the necessary timing signals and simultaneously off loads the microprocessor and controller from the details of the LCD, thereby allowing the processor and the controller to carry out their other operations efficiently.December 2007, version 1.0Figure1 shows a block diagram for the LCD controller. The three mainmodules inside the LCD controller are the finite state machine (FSM), theuser flash memory (UFM), and the clock divider module. The interfacingsignals to the LCD module are E, RS, RW, and DB0-DB7. This designsuccessfully interfaces the processor and the LCD module through thecontroller. For more information on the signals, refer to Table1.Figure1.LCD ControllerInitializing the LCD Module and the Finite State MachineThe FSM is made of eight different states. It is used to initialize the LCD,display a message after initialization is complete, and to write to and readfrom the LCD. The initialization steps for the LCD module are shown inFigure2.Figure2.LCD Module Initialization Flow Chartf f To simplify initialization, a delay of 15ms is provided after each command is sent (instead of checking the status of the busy flag). However, while writing data into the LCD module, the status of the busy flag is checked after each data write. This makes the writing procedure faster.For more information about initializing the LCD module and the various commands supported by it, see the Optrex LCD Manual at the following link:http s:///User Flash MemoryThe UFM inside the MAX II CPLD is used to store the ASCII values of the characters to be displayed as soon as the controller is turned on. It is instantiated using the UFM megafunction. Parallel interface programs the UFM with the help of a hexadecimal (Intel_Format) file (.hex). For more information on creating a .hex file using the Quartus® II software, refer to the following link:/support/software/nativelink/quartus2/glossa ry/def_rif.htmlFor more information about instantiating the UFM using the MegaWizard® Plug-In Manager, refer to the Using User Flash Memory in MAX II Devices chapter in the MAX II Device Handbook.Clock DividerThe clock divider module reduces the frequency of the internal oscillator output so that the timing requirements of the LCD module are met and the controller performance is satisfactory.

Use this design source code and allocate the data bus and control lines (input and output) to the general purpose I/O (GPIO) lines of the MAX II CPLD. Use the internal user flash memory to store any default message you wish to display on the LCD module upon power on. Use the memory editor in the Quartus II software to create a memory initialization file to store the default message in the LCD module.The following details the implementation of this design on the MDN-B2 demo board. Table 2 lists the EPM240G pin assignments for this design example.1Unused pins are assigned as input tri-stated in the Quartus II software’s device and pin option settings prior to compilation.Design Notes To demonstrate this design on the MDN-B2 demo board, complete the following:1.Download the design on to the MAX II CPLD through the JTAG header JP5 and a conventional cable (ByteBlaster ™II, USB-Blaster ™). Programming requires the demo board to be switched on (slide switch SW1). After programming, turn off the power.Table 2.Design Implementation Using the MDN-B2 Demo Board EPM240G Pin Assignments Signal Pin Signal Pin DB[0] pin 53DB[4]pin 1DB[1] pin 98DB[5] pin 96DB[2] pin 52DB[6]pin 92DB[3] pin 97DB[7]pin 95data[0] pin 55data[4]pin 61data[1] pin 56data[5]pin 66data[2] pin 57data[6]pin 67data[3] pin 58data[7]pin 68E pin 99rst pin 77RS pin 100ack pin 69RW pin 54we pin 812.Ensure that the memory file lcd_new.hex (included with the sourcecode files) is placed in the Quartus II software’s project library.3.Connect the LCD module to the board using the suppliedinterconnect cable.

This DC socket has conventional polarity (the inner pin is positive). You can also use3xAA or AAA batteries to power up the LCD module.6.Connect the 5V power supply to the LCD module first. Thenconnect the interconnect cables as mentioned in step 4.7.Turn on the power supply to the MDN-B2 demo board using theslide switch SW1.8.Observe the default message on the LCD module. This message ispre-programmed in the UFM of the MAX II CPLDs using thelcd_new.hex file. The controller reads this message only once upon power-on.e the reset push button SW6 on the demo board to reset the LCDmodule. Note that after reset, the cursor on the LCD is in its firstcharacter position on the first row and is blinking.10.For the purpose of this exercise, you can enter any ASCII datacorresponding to a character you wish to display using the SW5switch (the 8-way dual in-line package (DIP) GPIO input switch on the demo board). The switch sets a logic 0 when ON, and a logic 1 when OFF. Switch #1 is the LSB on this ASCII data byte.11.Press button SW8 on the demo board to write enable the controller,which enables it to take in fresh data set by the SW5 switch. Thedemo board takes in new data as long as the SW8 button is pressed, and at a rate of approximately 4.25 kHz. It updates all characters on both rows almost immediately after pressing the SW8 button.1This design is made to work specifically with Optrex’s SC1602DLCD module. This LCD module has non-consecutive addresseson the last character of the first row and first character of thesecond row on the LCD. This design makes suitable alterationsto match this arrangement.Source Code This design has been implemented in Verilog and successful operationhas been demonstrated using the MDN-B2 demo board, as referenced inthe documentation.

Name: _______________________________ Date: ___________SIK LCD TutorialIntroductionAn LCD is short for ​L iquid​​C rystal​​D isplay​. When current is applied to this special kind of crystal, it turns opaque. This is used in a lot of calculators, watches, and many simple displays. Adding an LCD to your project will make it super portable and allow you to integrate up to 32 characters (16 x 2) of information into your Arduino project. The LCD has a lot of pins (16 pins in total) that we’ll show you how to wire up. Lucky for you, four of the pins will not be used.Let's take a look at how it works.Controlling the LCDThe LCD has 16 pins. The pins are numbered from left-to-right 1 through 16. The LCD utilizes an extremely common parallel interface LCD driver chip from Hitachi called the HD44780. Thankfully, the Arduino community has developed a library to handle a great deal of the software to hardware interface.The pins are described as shown in the diagram below:Pin Descriptions:Pin 1 -- GroundPin 2 -- VDD (5V) Power for the LCDPin 3 -- Contrast Adjust (0 - 5V)Pin 4 -- Register Select (RS)Pin 5 -- Read / Write Select (R/W)Pin 6 -- EnablePins 7-10 -- data lines d0 - d3 (not used)Pins 11 - 14 -- data lines d4 - d7 (datatransferred in 4-bits at a time)*Pin 15 -- Backlight Power (5V)Pin 16 -- Backlight GND (GND)Wiring and Hook‐up GuideYou will connect 6 pins from the Arduino to the LCD. These 6 pins will be for the register select, enable, and four data lines. The rest of the pins on the LCD will be connected to either 5V, GND, or not connected at all.sparkfun​e ducation​.com1. Connect 5V and GNDFirst, connect the 5V and GND pins from the Arduino to the breadboard power rails.2. Mount the LCDInsert the LCD starting on the top-most row of the breadboard. Notice that there are a total of 16 pins on the LCD. The last pin on the LCD should be in the first row of the breadboard.3. Contrast ControlPin 3 on the LCD controls the contrast and brightness of the LCD. Using a simple voltage divider with a potentiometer connected between 5V and GND, connect the center pin (wiper) of the potentiometer to pin3 on the LCD. As you rotate the knob on the potentiometer, you should notice that the screen will get brighter or darker (as soon as we connect up power to it).4. Adding PowerThe LCD has two separate power connections. One for the LCD itself and another one for the backlight. Add the following four wires to your project for both the LCD power and the backlight power.●Connect pins 1 and 16 on the LCD to GND and pins2 and 15 on the LCD to 5V.5. Read / WriteOne of the pins on the LCD is to control whether or not you’re reading data from the LCD or writing data to the LCD. Since we’re just using this as an OUTPUT device, we’re going to tie this pin LOW. This forces it into the WRITE mode.Connect:●Connect Pin 5 on the LCD to GND.6. Enable and Register SelectData is sent to the LCD in parallel across 4 data lines. The data in synchronized and loaded in with signals on these two wires.Connect:●Pin 8 on the Arduino to pin 4 of the LCD.●Pin 9 on the Arduino to pin 6 of the LCD.7. Data linesNow, connect up the final four data lines from the Arduino to the LCD. These four lines transfer data to the LCD in two 4-bit ​n ibbles​.Connect:●Pin 10 on the Arduino to pin 11 of the LCD.●Pin 11 on the Arduino to pin 12 of the LCD.●Pin 12 on the Arduino to pin 13 of the LCD.●Pin 13 on the Arduino to pin 14 of the LCD.8. That’s it!That’s it. Now that you have all of the wires, let’s take a look at the new code. To control the LCD, we’re going to use some functions included in the ​L i q u i d C r y s t a l library.Let’s take a look at the code.Arduino LiquidCrystal LibraryThe Arduino community has a library called ​L i q u i d C r y s t a l​that simplifies the controls and signals to the LCD. To use this, add this line to the very first line of code:#i n c l u d e​ ​<L i q u i d C r y s t a l.h>This includes additional code and functions needed to interface with the LCD. Pay close attention to the spelling, capitalization, and punctuation. To initialize the LCD, we declare a ​L i q u i d C r y s t a l​object using this line of code:// L i q u i d C r y s t a l l c d(R S, E n a b l e, d4, d5, d6, d7); ­­ 6 c o n t r o l / s i g n a l p i n sL i q u i d C r y s t a l​ l c d​(​8​,​ ​9​,​ ​10​,​ ​11​,​ ​12​,​ ​13​);This initializer uses 6 parameters and specifies which Arduino pins are connected to the LCD's RS pin, Enable pin, and data pins: d4, d5, d6, and d7. In our line of code, we simply used Arduino pins 8 - 13 sequentially, but you don't have to do this. It's up to you. Use whatever I/O pins you have available on your Arduino.Using the LiquidCrystal LibraryNow that you have declared a ​L i q u i d C r y s t a l​object, you can access special methods (aka functions) that are specific to the LCD. Here is an overview of a few that you will find useful:// i n i t i a l i z e s i n t e r f a c e t o t h e L C D s c r e e n a n d s p e c i f i e s t h e s i z e (w i d t h a n d h e i g h t).l c d​.​b e g i n​(​16​,​ ​2​);​// ​c l e a r s t h e L C D s c r e e n a n d m o v e s t h e c u r s o r t o t h e u p p e r­l e f t c o r n e r.l c d​.​c l e a r​();// p r i n t s t e x t t o t h e L C D.l c d​.​p r i n t​(​"Y o u r m e s s a g e")// P o s i t i o n t h e L C D c u r s o r; a n y n e w t e x t w r i t t e n t o t h e L C D w i l l b e d i s p l a y e d s t a r t i n g h e r e.// T h e u p p e r l e f t c o r n e r i s c o n s i d e r e d c o l = 0, r o w = 0l c d​.​s e t C u r s o r​(​c o l​,​ r o w)Example Sketch Using the LiquidCrystal LibraryThis is a little example code to get started with.

CONSTITUTION:A vertical synchronism generation part 26 and a horizontal synchronism generation part 27 transfer 'L' to all bits of the 1st shift register 15 of the liquid crystal panel for the certain period after resetting to make a row-side driving circuit 16 not operate, thereby making no display on the liquid crystal panel. Then a synchronizing signal corresponding to a set value from a CPU 2 is generated. Consequently, the initial state of the display screen can be determined without controlling the power source 24 for the liquid crystal display panel.申请人：MATSUSHITA ELECTRIC IND CO LTD,松下電器産業株式会社地址：大阪府門真市大字門真1006番地国籍：JP代理人：滝本 智之更多信息请下载全文后查看。
