The D1 and D2 protection diodes allow the 5V and 3V3 pins to be used independently as input or output power supplies (see Figure 3). The 5V and 3V3 pins can be used as an output power supply for use by an application board connected on pin headers (P1 to P3). In such a case, the 3V3 pin provides only a 3V power supply and the power consumption must be lower than 100mA. The 5V and 3V3 pins can also be used as an input power supply for the board when the USB connector is not connected to the PC.3.4 LEDs●LD1 COM: Red LED indicates communication in progress between PC and ST -Link.●LD2 PWR: Red LED indicates that the board is powered.●LD3 PE7: Green LED is a user LED connected to the I/O PE7 of the STM8L152C6T6.●LD4 PC7: Blue LED is a user LED connected to the I/O PC7 of the STM8L152C6T6.3.5 Push buttons●B1 RST: Push button is used to RESET the STM8L152C6T6.●B2 USER: User push button connected to the I/O PC1 of the STM8L152C6T6.No jumpers on CN3Hardware and layout UM097014/29Doc ID 17693 Rev 13.6 Built-in IDD measurement circuitThe STM8L-DISCOVERY built-in I DD measurement circuit allows the consumption of the STM8L152C6T6 to be measured and displayed on the LCD Glass while the MCU is in Run or Low power saving modes.●JP1 in ON position: STM8L152C6T6 is powered through I DD measurement circuit (default).●JP1 in OFF position: STM8L152C6T6 is powered directly by +3V3, I DD measurement circuit is bypassed.Note:When jumper JP1 is removed the current consumption of the STM8L152C6T6 can be measured by connecting an ammeter between jumper JP1 pin 1 and pin 2.For Imeasurement by the MCU itself, the circuit below is implemented on the STM8L-measurement timing according to Figure 11.UM0970Hardware and layout 3.6.3 Low power mode I DD measurement principleThe principle used to measure a current when the STM8L152C6T6 is in Low power mode is:1.Configure ADC to measure voltage on the IDD_Measurement pin.2. Configure PE6 to serve as wakeup pin.3. Enter Low power mode after setting IDD_CNT_EN (PC4) signal low.4. IDD_WAKEUP rising edge wakes up the MCU after around 300ms.5. Start ADC conversion as soon as possible after wakeup in order to measure thevoltage corresponding to Low power mode on capacitor C11.6. Reset the counter by programming IDD_CNT_EN high (in less than 70ms after thewakeup) to avoid the R21 2KΩ resistor being connected later in Run mode.The measurement timing is given in Figure11. In Low power modes, the 2KΩ resistor isconnected when T1 goes off after entering Low power mode. Q13 output of the counterallows connection of the 2KΩ resistor when the current I DD becomes very low.Figure11 shows how the counter and T1 ensure that, 150ms after IDD_CNT_EN fallingedge, the shunt resistor R21 is connected between VDD_MCU and the power supply inorder to reduce the measurement range to 30uA full scale. Then after another 150ms forcurrent stabilization, R21 is shorted, the IDD measurement is stored in C11, and the MCU iswoken up. After wakeup the MCU can measure the IDD current corresponding to the Lowpower mode stored in C11.Figure 11.STM8L-DISCOVERY I DD Low power mode measurement timing diagramThe Low power mode measurement procedure can be used in Halt or Active halt mode if theI DD current does not exceed 30uA, otherwise the I DD measurement procedure in Run modeshould be used up to 30mA.Doc ID 17693 Rev 115/29Hardware and layout UM097016/29Doc ID 17693 Rev 13.6.4 Ibias current measurement procedureIn Low power mode the bias current of operational amplifier input (U4 pin 4) is not negligiblecompared to I DD current (typical Ibias is ~240 nA). T o obtain a reliable STM8L152 I DD measurement it is mandatory to subtract the bias current from the I DD low power measurement since this current is not sinked by the MCU. Ibias is measured duringproduction test and stored in the MCU EPROM. The demonstration software, Discover, uses this value to display the correct I DD . The Ibias measurement procedure is part of the demonstration software and can be launched if required.The procedure for Ibias measurement (implemented in the Demo) is:1.Power off the board (disconnect the USB cable).2. Set jumper JP1 to OFF position (pins 1 and 2).3. Push down B2 (USER button), power on the board from the USB.4. Wait at least 1 second before releasing B2, the LCD displays the Ibias measurement.5. Power off the board (disconnect the USB cable).6.Set jumper JP1 to ON position (pins 2 and 3). The Ibias value is now stored. The bias current is then subtracted from the I DD measurement performed in Low power mode.3.7 Solder bridgesTable 4.Solder bridgeBridgeState (1)1.Default state is in bold type.DescriptionSB1,2(X2 crystal)Off P A2, P A3 are disconnected from P1X2, C19, C20 and R24 provide a clock as shown in schematics On P A2, P A3 are connected to P1 (X2, C19, C20, R24 must not be fitted)SB3,5,7,9 (DEFAULT)On Reserved, do not modify SB4,6,8,10(PRG-32)Off Reserved, do not modifySB11,12,14(IDD_Measurement)Off PFO, PE6, PC4 are available and IDD module cannot be used JP1 must be set to OFFOn PFO, PE6, PC4 are used by IDD module JP1 must be set to ONSB13,15(X3 crystal)Off PC5, PC6 are only connected to P2 (but do not remove X3, C21, C23, R27)On PC5, PC6 are connected to P2.

In this case the 2 LCDpins must not be plugged into the LCD socket. To proceed with this configuration, removethe LCD carefully, slightly open the COM2 and COM3 pins (pin 13 and pin 14) of the LCD,then replug it in the socket.Characteristics overview:●24 segments and 4 commons●Drive method: multiplexed 1/4 duty, 1/3 bias●Operating voltage: 3V●Operating temperature: 0 to 50°C●Connector: 28-pin DIL 2.54mm pitchNote:When the LCD is plugged, all I/O ports listed in Table5 are unavailable.

25/37Debug system overview UM04706/37Doc ID 14024 Rev 21Debug system overview The STM8 debug system interface allows a debugging or programming tool to be connected to the MCU through a single wire bidirectional communication based on open-drain line.It provides non-intrusive read/write access to RAM and peripherals during program executionThe block diagram is shown in Figure 1.Figure 1.Debug system block diagramThe debug module uses the two internal clock sources present in the device, the LSI Low Speed Internal clock (usually in the range 30 kHz-200 kHz, depending on the product) one and the HSI High Speed Internal clock (usually in the range 10 MHzto 25 MHz, depending on the device). The clocks are automatically started when necessary.SWIM EntryLSI oscillator HSI oscillatorComm Layer Command DecodeDebug module (DM)STM8CorePeripherals SWIM pinP e r i p h e r a l B u sCPU BusSWIM RAMFlash/R A M B u sSTM8Data EEPROM调试系统总览UM0470Communication layerDoc ID 14024 Rev 27/372 Communication layerThe SWIM is a single wire interface based on asynchronous, high sink (8 mA), open-drain,bidirectional communication.While the CPU is running, the SWIM allows non-intrusive read/write accesses to be performed on-the-fly to the RAM and peripheral registers, for debug purposes.In addition, while the CPU is stalled, the SWIM allows read/write accesses to be performed to any other part of the MCU’s memory space (Data EEPROM and program memory).CPU registers (A, X, Y , CC, SP) can also be accessed. These registers are mapped in memory and can be accessed in the same way as other memory addresses.●Register, peripherals and memory can be accessed only when the SWIM_DM bit is set. ●When the system is in HALT , WFI orreadout protection mode, the NO_ACCESS flag in the SWIM_CSR register is set. In this case, it is forbidden to perform any accesses because parts of the device may not be clocked and a read access could return garbage or a write access might not succeed.The SWIM can perform a MCU device software reset.The SWIM pin can also be used by the MCU target application as a standard I/O port with some restrictions if you also want to use it for debug. The safest way is to provide a strap option on the application PCB.

ST单片机STM8S开发入门教程最近ST在国内大力推广他的8位高性价比单片机STM8S系列，感觉性能上还是非常不错的，网上稍微看了点资料，打算有机会还是学习一下，先入门为以后做好技术积累。

好了，长话短说。

手上拿到一套ST最近做活动赠送的三合一学习套件，上面包括STM32F小板、ST LINK小板、STM8S小板，做工很精致，相信很多朋友也收到了。

既然当初去申请了，人家也送了，总得把用起来吧，放着吃灰尘是很可惜的^_^ 。

好，步入正题，刚开始在论坛上逛了一圈，感觉STM8S的资料实在太少，都是官方的应用资料，没有什么入门介绍，连需要安装什么软件都搞不清楚。

偶的电脑光驱坏了，所以也读不出光盘里有什么东西，所以只能到处瞎摸，还是ourdev论坛好，嘿嘿，仔细看了几个帖子，总算明白大概是什么样的开发环境了。

用C语言开发STM8S，需要安装两个软件：1、STVD IDE开发环境；2、COSMIC for STM8 C编译器。

STVD可以到官网下载，下载地址：COSMIC 需要申请LICENSE，比较繁琐，刚好坛子有人传了一个免安装无限制版本的，偶就赶紧下载了，大家可以去下载，仅做为个人学习使用。

下载地址：软件下载后，只需安装STVD。

从上面地址下载的COSMIC不用安装，只要解压到硬盘即可。

后面建立工程的时候设置好路径即可。

下面一步一步开始啦～一、安装好STVD后，桌面上建立了两个快捷图标，ST Visual Develop就是STVD了。

ST Visual Programmer是编程软件，可以配合ST LINK对STM8S进行编程烧录。

二、双击运行ST Visual Develop，启动STVD开发环境。

执行Workspace，在New Workspace 窗口里选择Create workspace and projects，点击“确定”建立工作组和工程三、在Workspace 里输入Workspace名称，由于最终我们要测试一个现成的LED程序，所以偶写了led，随你喜欢了，呵呵。
