AX46x is used with glass, enamel and antimony pH electrodes and metal Redox sensors, providing measurements with exceptional accuracy and performance.AX400 Series analyzers are available for either wall-/pipe- or panel-mounting and are rated to IP66/NEMA 4X.High Functionality as StandardAll versions are supplied with two, fully isolated current outputs as standard, that can be assigned to the measured parameter,sample temperature or any appropriate calculated variables.Three programmable relay set points are available that can also be assigned as required.Innovative features such as power-saving display and a diagnostic current output option all contribute to a low cost of ownership.Plug-and-Produce Expanded ControlAn advanced function card provides an additional two current outputs and two further alarm relays that can be assigned to either measured values or sample temperature.ABB Plug-and-Produce software automatically reconfigures the analyzer if an option board is added later. No user programming is necessary.A real-time clock and logbook are also included making the full-facility versions extremely powerful and versatile.Significantly Reduced Maintenance CostsThe AX400 analyzers are supplied as standard for 85 to 265V AC operation. There are no inner switches to set.They can also be provided for 24V AC or 12 to 30V DC supply and recognize automatically which of the two supplies is being used. 24V DC operation reduces maintenance costs significantly by negating the need for costly, yearly safety tests to ensure compliance with safety procedures.Energy Saving DisplayThe backlit display has been designed to operate in all types of environments and shows both the measured parameter(s) and,on a separate 16-character display line, diagnostic and computed information.On dual-input analyzers both measured parameters are displayed simultaneously.For conservation of energy, the backlight can be set to switch off automatically after 60s of inactivity.Backlight Can Be Set to Switch Off When InactiveAX400 Termination Chamber Makes Access EasyEasy-Access Installation TerminalsE asy access to the terminations ensures rapid and cost-effective installation. The wall-/pipe-mount version has been designed to ensure that cable connection is simple and convenient. Ingress protection of the electronics section is retained even when the terminal compartment cover is opened.AX400 OutputsSingle and Dual Input Analyzers for pH/Redox (ORP)AX460, AX466 & AX416SS/AX4PH_63Waste Treatment pH & Redox (ORP)pH and Redox (ORP) are essential control parameters when removing toxic chromium ions from waste water in metal-finishing applications. Dual pH and Redox analyzers and integral control simplifies installation and reduces investment costs.Dual Input Measurement for Critical DutiesThe AX400 enables two continuous measurements with simultaneous local display and retransmission. This capability provides an on-line validation of the process measurement.Making two simultaneous measurements and configuring one ofJust-in-Time MaintenanceSingle and Dual Input Analyzers for pH/Redox (ORP)AX460, AX466 & AX416SS/AX4PH_64Reduced Maintenance Through In-line CleaningMany installed pH sensors benefit from regular cleaning. When carried out manually, this can be laborious and costly – so is often ignored. Advanced AX400 pH analyzers make it possible to automate sensor cleaning by using a programmable wash-timer contact to activate a cleaning agent valve or pump.Pulsed water-wash and jet-wash chemical clean actions are standard, user-selectable functions. The frequency and duration of the wash can be tuned to meet the requirements of the application.For chemical cleaning a 60 liter (13 gallon) sensor cleaning station can be supplied (model no. AA0010), complete with delivery pump and low level alarm. Chemical cleaning has proved particularly successful on potable drinking water plants where manganese and iron in the sample can create unacceptably high levels of maintenance. E ffective cleaning reduces cost of ownership.Efficient Auto-cleaning Control for One or Two Sensor SystemsCombined Conductivity and pHThe AX416 version measures conductivity and pH with the same analyzer. The option board provides the capability to retransmit pH, conductivity and both sample temperatures. Five programmable alarms can be assigned to suit the needs of the application, enabling even the most demanding requirements to be met.AX460 Integral P, PI and PID ControlThe single input AX460 analyzers incorporate three-term PID Control, offering three modes of sophisticated control: analog,pulse length (time proportional) and pulse frequency. These aresupplied as standard and can be operated in direct- or reverse-acting mode, dependent upon the application.Auto/Manual and Bumpless TransferAn auto/manual feature is incorporated for rapid manual access to the control functions. The controller facilitates bumpless transfer between manual and auto modes, providing the measured variable is within the proportional band and some integral action time has been programmed.Current Acting ControlSimultaneous Conductivity and pH MeasurementSingle and Dual Input Analyzers for pH/Redox (ORP)AX460, AX466 & AX416SS/AX4PH_65Bi-directional ControlBi-directional ControlAs well as single set point control for both acid and base addition, the AX460 analyzer can be configured with independent controllers.To avoid control overlap, a minimum of 0.5pH difference (or deadband) between the set points is essential. The difference between the set points varies depending upon the application.Control of each set point can be configured independently as either P or PI control in this mode. The setting of proportional band or integral action can also be different for each set point.Time Proportioning Control (Pulse Length)With time proportioning control, the AX460 analyzer’s control signal output is in pulses, the duration of which changes in proportion to the system error. The pulses are delivered by varying the length of time that the alarm/control contact is activated.Time Proportioning Control is used generally to control dosing by low-cost solenoid valves or metering pumps and is also known as pulse-length proportional or Mark Space control.Pulse-frequency Proportional ControlPower Failure RecoveryIn the event of a power failure the user can configure the control mode to be Auto, Manual or Last. This optimizes control conditions on power-up to ensure rapid recovery of process control.Time Proportioning ControlPulse-frequency Proportional ControlImpulse pumps dosing chemical reagents are controlled easily by the AX460 analyzer’s pulse-frequency proportional control output. In this case, the pulse length of the alarm/control contact is fixed and the frequency of the delivered pulses increases in proportion to the system error, as set by the proportional band.Diaphragm metering pumps must have a remote pulse input capability in order to utilize this function.Pulse-frequency control in the AX460 analyzer operates by pulsing a relay on for 300ms and off for a period of time determined by the pulse frequency. The pulse frequency (PFr) is adjustable between 1 and 120 pulses per minute. The greater the difference between the measured variable and the set point the greater the pulse frequency.ExampleIf the pulse frequency is set at 120 pulses per minute and the percentage output is 100% then the pulse rate is 2 pulses per second. If the percentage output is reduced to 50%, the pulse rate falls to one pulse per second.Single and Dual Input Analyzers for pH/Redox (ORP)AX460, AX466 & AX416SS/AX4PH_66SpecificationpH/Redox (ORP) –

With Open746I-C, both RGB Header interface and RGB Cable interface are compatible, so we provide two examples for both interfaces.Clean.bat: Batch files sued to clean redundant files generated when compiling.STM32F7 EXAMPLESDevelopment board used is Waveshare Open746I-C, chip is STM32F746IGT6. The project uses HAL libraries.HARDWARE CONNECTIONFor this board, we provide two examples, with same functions. The only difference of them is that the touch interfaceRGB Header interface (Interface 1)RGB Cable interface (Interface 2), the only difference between Interface 1 is touch pins.EXPECTED RESULT1.Display a picture2.Display English and Chinese characters3.Draw point, line, rectangle and circle.4.Display the points where finger touch, supports up to 5-points touchSTM32F4 EXAMPLESDevelopment board used is Waveshare Open429I-C, chip is STM32F429IGT6. The project uses HAL libraries.HARDWARE CONNECTIONThe RGB Cable interface (Interface 2) is used for resistive touch screen, isn’t compatible with capacitive screen, therefore, we only provide RGB Header example (Interface 1) for this board. RGB Header Interface (interface 1)EXPECTED RESULT1.DISPLAY a picture2.Display English and Chinese characters3.Draw points, line, rectangle and circle4.Display points touched by fingers, supports up to 5-points touch1.Why the codes used RGB565 instead of RGB888 for color displaying?- The data of RGB888 are too much, required much more RAM. SDRAM is 16-bit input/output. If we use RGB888, we should save RGB data by writing several times, and cost much more times and CPU. In fact, even we use RGB565 to transmit data, LCD controller will convert it to RGB888 format and needn’t cost external CPU。

在Linux 系统中，SetUnhandledExceptionFilter是Windows 平台上的函数，用于设置当未处理的异常发生时的处理程序。

然而，Linux 并没有一个直接对应的函数。

在Linux 中，你可以使用信号（Signals）来处理未处理的异常或错误。

当一个进程收到一个信号时，它可以执行一些操作，例如终止进程或进行某种恢复。

例如，你可以使用signal函数来设置一个信号处理函数。

下面是一个简单的例子，展示了如何设置一个处理SIGSEGV（段错误）的信号处理函数：
c复制代码
#include<signal.h>
#include<stdio.h>
void handle_segv(int signal) {
printf("Caught segmentation fault!\n");
// 可以在这里添加代码进行清理或恢复操作
exit(1);
}
int main() {
// 注册信号处理函数
signal(SIGSEGV, handle_segv);
// 引发段错误的代码（例如访问无效的内存）
// ...
return0;
}
在这个例子中，当程序发生段错误时，handle_segv函数会被调用，然后程序会打印一条消息并退出。

如果你想要捕获所有的信号，你可以使用sigaction函数，或者简单地使用signal函数为所有信号设置相同的处理函数。

但要注意，某些信号是不能被捕获的，例如SIGKILL。

CC110x/CC111x OOK/ASK Register SettingsBy Sverre HellanKeywordsOOKASKPER (Packet Error Rate)CC1100CC1100ECC1101CC1110CC1111CC4301 IntroductionThis design note provides guidelines forfinding optimum register settings forOOK/ASK operation. The starting point forthe optimization is the preferred settingsgiven by the SmartRF®Studio SW. Theuser needs to measure the sensitivity(PER) over the full input dynamic range todetermine the optimum settings.This design note uses CC1101 as anexample on how to find optimum registersettings, but it is also applicable forCC1100, CC1100E, CC1110, CC1111,and CC430.Table of ContentsKEYWORDS (1)1INTRODUCTION (1)2ABBREVIATIONS (2)3OOK/ASK REGISTER SETTINGS (3)3.1AGC S ETTINGS (3)3.2IF F REQUENCY (4)3.3P ROCEDURE FOR F INDING OOK/ASK S ETTINGS USING S MART RF®S TUDIO (5)4GENERAL INFORMATION (8)4.1D OCUMENT H ISTORY (8)2 AbbreviationsAGC Automatic Gain ControlASK Amplitude Shift KeyingEM Evaluation Module2-FSK Frequency Shift KeyingGFSK Gaussian shaped Frequency Shift KeyingIF Intermediate FrequencyMSK Minimum Shift KeyingOOK On-Off KeyingPER Packet Error RateSW Software3 OOK/ASK Register Settings3.1 AGC SettingsThe register settings provided by SmartRF®Studio have been optimized for 2-FSK/GFSK/MSK modulation and when using one of the preferred settings and only changing the modulation format to OOK/ASK, the AGC settings might result in unstable or non-optimum reception (i.e. degraded sensitivity). This is pictured in Figure 1.Figure 1. Example of Unstable, Non-Optimum, and Optimum ReceptionThe optimum AGC settings change with RX filter bandwidth and data rate, but for OOK/ASK the following has been found to give good results:AGCCTRL2 = 0x03 to 0x07AGCCTRL1 = 0x00AGCCTRL0 = 0x91 or 0x92In the example shown in Figure 2, the best sensitivity is achieved with AGCCTRL2 = 0x04, AGCCTRL1 = 0x00, and AGCCTRL0 = 0x92. Please note that optimum register settings change with data rate so it is important to measure sensitivity for different combinations of AGCCTRL2 and AGCCTRL0. Furthermore, as shown in Figure 1, some combinations of AGC settings results in unstable reception. That is, for some input power levels above the sensitivity limit there will be degraded packet error rate (PER). It is therefore important to check the PER for the entire dynamic range and not only at the sensitivity limit. One option is to check the PER for every 2 dB increase in input power level.AGCCTRL2.MAGN_TARGET[2:0] is used to set an on-chip target value for the peak signal amplitude. MAGN_TARGET is used by the AGC loop to set the correct gain.AGCCTRL0.FILTER_LENGTH[1:0] is used to configure the ASK decision boundary. If the ASK decision boundary is set to 8 dB, the “low” bit must be at least 16 dB below the “high” bit.Figure 2. PER versus Input Power Level for Different AGC Register Settings (3.8 kBaud,100 kHz RX Filter Bandwidth) 3.2IF FrequencyRegister FSCTRL1 sets the IF frequency and the optimum value is different for different RX filter bandwidths. It is therefore recommended to find the FSCTRL1 setting using one of thepreferred RX filter bandwidth settings in SmartRF ®Studio (see Figure 3). If the wanted RX filter bandwidth is not given by one of the preferred settings, choose the FSCTRL1 setting for the first RX filter bandwidth that is wider than the wanted RX filter bandwidth.As an example, for a wanted 150 kHz RX filter bandwidth use the FSCTRL1 setting given for 232 kHz RX filter bandwidth.RX filter bandwidthsused by preferred settings:58 kHz, 100 kHz, 232 kHz, 325 kHz, 540 kHz, 812 kHzFigure 3. Available RX Filter Bandwidths Given by the Preferred Settings in SmartRF ®StudioNote that the FREND1, FIFOTHR, TEST2, and TEST1 register settings change for different RX filter bandwidths.FREND1:RX filter bandwidth > 101 kHz, FREND1 = 0xB6RX filter bandwidth ≤ 101 kHz, FREND1 = 0x56TEST2:RX filter bandwidth > 325 kHz, TEST2 = 0x88RX filter bandwidth ≤ 325 kHz, TEST2 = 0x81TEST1:RX filter bandwidth > 325 kHz, TEST1 = 0x31RX filter bandwidth ≤ 325 kHz, TEST1 = 0x35FIFOTHR:RX filter bandwidth > 325 kHz, FIFOTHR = 0x07RX filter bandwidth ≤ 325 kHz, FIFOTHR = 0x473.3 Procedure for Finding OOK/ASK Settings using SmartRF® StudioAs an example, assume 4.8 kBaud data rate and 203 kHz RX filter bandwidth.1) Use SmartRF®Studio to find the optimum IF frequency. Select the preferred setting that has an RX filter bandwidth equal to the wanted bandwidth. If the wanted RX filter bandwidth is not given by one of the preferred settings, chose the first RX filter bandwidth that is wider than the wanted bandwidth. For a 203 kHz wanted RX filter bandwidth, select the 232 kHz RX filter bandwidth for optimum IF frequency.2) Change the data rate and the RX filter bandwidth to the wanted values. Change the modulation format to ASK/OOK. Press “Reset CC1101 and write settings” (if SmartRF® Studio is being used to control a CC1101EM) and then “Copy settings to Register View”3) In Register View, change the AGCCTRL2, AGCCTRL1, and AGCCTRL0 settings as explained in Section 3.1. Make sure the FSCTRL1, FIFOTHR, FREND1, TEST2, and TEST1 registers are set as explained in Section 3.2. It is possible to print the register settings to a file using “Export CC1101 Registers” under “File”.Press the “Write” butt on for the register to be updated if SmartRF® Studio is being used to control a CC1101EM.4) If SmartRF ®Studio is being used to perform the test, go back to Normal View. Check the Manual Init box for the changes done in Register View to take effect.4 General Information4.1Document HistoryIMPORTANT NOTICETexas Instruments Incorporated and its subsidiaries(TI)reserve the right to make corrections,modifications,enhancements,improvements, and other changes to its products and services at any time and to discontinue any product or service without notice.Customers should obtain the latest relevant information before placing orders and should verify that such information is current and complete.All products are sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment.TI warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with TI’s standard warranty.Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty.Except where mandated by government requirements,testing of all parameters of each product is not necessarily performed.TI assumes no liability for applications assistance or customer product design.Customers are responsible for their products and applications using TI components.To minimize the risks associated with customer products and applications,customers should provide adequate design and operating safeguards.TI does not warrant or represent that any license,either express or implied,is granted under any TI patent right,copyright,mask work right, or other TI intellectual property right relating to any combination,machine,or process in which TI products or services are rmation published by TI regarding third-party products or services does not constitute a license from TI to use such products or services or a warranty or endorsement e of such information may require a license from a third party under the patents or other intellectual property of the third party,or a license from TI under the patents or other intellectual property of TI.Reproduction of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties,conditions,limitations,and notices.Reproduction of this information with alteration is an unfair and deceptive business practice.TI is not responsible or liable for such altered rmation of third parties may be subject to additional restrictions.Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice.TI is not responsible or liable for any such statements.TI products are not authorized for use in safety-critical applications(such as life support)where a failure of the TI product would reasonably be expected to cause severe personal injury or death,unless officers of the parties have executed an agreement specifically governing such use.Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications,and acknowledge and agree that they are solely responsible for all legal,regulatory and safety-related requirements concerning their products and any use of TI products in such safety-critical applications,notwithstanding any applications-related information or support that may be provided by TI.Further,Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in such safety-critical applications.TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are specifically designated by TI as military-grade or"enhanced plastic."Only products designated by TI as military-grade meet military specifications.Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at the Buyer's risk,and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use.
