stm8s和stm8l低功耗对比
stm8s和stm8l低功耗对⽐stm8s和stm8l低功耗对⽐ 在低功耗应⽤中，⼀般来说mcu是常态halt模式，然后偶尔被唤醒(外部中断或者内部定时唤醒)进⼊运⾏模式。
所以对⽐低功耗性能，⼀般来说只需要对⽐run模式和halt下的功耗即可，因为项⽬选⽤的是通过内部定时器唤醒，所以选⽤active halt mode。
以下是stm8s003和stm8l151在这两种模式下的功耗对⽐：run mode：stm8sstm8l对⽐ 在使⽤同样的16M内部RC振荡器情况下，stm8s 3.7ma,stm8l 3.54ma，两款mcu耗电量差不多。
active halt mode：stm8sstm8l对⽐ 在同样的关闭外设，且使⽤内部低速RC振荡器唤醒的情况下：stm8s 10ua，stm8l 0.54ua。
⼤约有20倍的差距，不过对于要求不是特别⾼的情况下，ua级别的差距影响不会太⼤。
实测：为了实际验证，分别将单⽚机焊接到空板⼦上编写代码进⾏测试。
stm8 编写如下代码：32ms唤醒⼀次主程序：void main(void){CLK_HSECmd ( DISABLE );CLK_SYSCLKConfig(CLK_PRESCALER_HSIDIV1);AWU_DeInit();AWU_Init(AWU_TIMEBASE_32MS);CLK_SlowActiveHaltWakeUpCmd(ENABLE); //关闭活跃停机模式下的电压调节器(MVR)CLK_FastHaltWakeUpCmd(DISABLE); //关闭快速唤醒FLASH_SetLowPowerMode(FLASH_LPMODE_POWERDOWN); //设置为停机后flash掉电GPIO_Init(GPIOA,GPIO_PIN_ALL,GPIO_MODE_OUT_PP_LOW_SLOW);GPIO_Init(GPIOB,GPIO_PIN_ALL,GPIO_MODE_OUT_PP_LOW_SLOW);GPIO_Init(GPIOC,GPIO_PIN_ALL,GPIO_MODE_OUT_PP_LOW_SLOW);GPIO_Init(GPIOD,GPIO_PIN_ALL,GPIO_MODE_OUT_PP_LOW_SLOW);GPIO_WriteLow(GPIOA,GPIO_PIN_ALL);GPIO_WriteLow(GPIOB,GPIO_PIN_ALL);GPIO_WriteLow(GPIOC,GPIO_PIN_ALL);GPIO_WriteLow(GPIOD,GPIO_PIN_ALL);AWU_Cmd(ENABLE);while(1){ halt();}}中断处理程序：INTERRUPT_HANDLER(AWU_IRQHandler, 1){/* In order to detect unexpected events during development,it is recommended to set a breakpoint on the following instruction.*/u8 awu_temp = 0;awu_temp = AWU_GetFlagStatus();}程序下载到单⽚机后，串到台式万⽤表上实测电流11ua,见下图：stm8l 编写如下代码：32ms唤醒⼀次主程序：void main(void){GPIO_Init(GPIOA, GPIO_Pin_All, GPIO_Mode_Out_PP_Low_Slow);GPIO_Init(GPIOB, GPIO_Pin_All, GPIO_Mode_Out_PP_Low_Slow);GPIO_Init(GPIOC, GPIO_Pin_All, GPIO_Mode_Out_PP_Low_Slow);GPIO_Init(GPIOD, GPIO_Pin_All, GPIO_Mode_Out_PP_Low_Slow);GPIO_Init(GPIOE, GPIO_Pin_All, GPIO_Mode_Out_PP_Low_Slow);GPIO_Init(GPIOF, GPIO_Pin_All, GPIO_Mode_Out_PP_Low_Slow);GPIO_Write(GPIOA,0x00);GPIO_Write(GPIOB,0x00);GPIO_Write(GPIOC,0x00);GPIO_Write(GPIOD,0x00);GPIO_Write(GPIOE,0x00);GPIO_Write(GPIOF,0x00);RTC_DeInit(); //初始化默认状态CLK_PeripheralClockConfig(CLK_Peripheral_RTC, ENABLE); //允许RTC时钟CLK_RTCClockConfig(CLK_RTCCLKSource_LSI, CLK_RTCCLKDiv_1); // 38K/1 RTC_WakeUpClockConfig(RTC_WakeUpClock_RTCCLK_Div2); //38/2=19KRTC_SetWakeUpCounter(19*32); //19*32 32msRTC_ITConfig(RTC_IT_WUT, ENABLE); //开启中断PWR_FastWakeUpCmd(DISABLE); //关闭快速唤醒功能PWR_UltraLowPowerCmd(ENABLE);//超低功耗RTC_WakeUpCmd(ENABLE);while(1){ halt();}}中断处理程序：INTERRUPT_HANDLER(RTC_CSSLSE_IRQHandler,4){/* In order to detect unexpected events during development,it is recommended to set a breakpoint on the following instruction.*/RTC_ClearITPendingBit(RTC_IT_WUT);}将程序下载到单⽚机后，串到台式万⽤表测试电流在4ua左右，见下图：。
stm8开发环境配置及测试
stm8开发环境配置及测试需要准备的软件，硬件，IAR for stm8 （EWSTM8）、stm8s标准固件库、ST-LINK、STM8s003f3核⼼板安装IAR（其中包括st-link的驱动），使⽤IAR新建⼀个⼯程，具体步骤如下：1,File->New->Workspace2,创建⼀个⼯程：Project->Create New Project...3,在弹出的对话框中选择C，-》OK4，根据提⽰保存你的⼯程5，从stm8s标准固件库中复制Libraries⽬录到你的⼯程⽬录，复制\STM8S_StdPeriph_Lib_V2.1.0\Project\STM8S_StdPeriph_Examples\GPIO到你的⼯程⽬录6，IAR的⼯程配置：在⼯程中添加两个组Libraries，MyApp。
右击你的⼯程->Add->Add Group7，将库中的*.c⽂件和主程序⽬录的*.c⽂件分别添加到Libraries, MyApp;右击相应组->add->add files8，选择单⽚机型号：右击你的⼯程Options->General Options->选择你单⽚机的型号9，配置头⽂件搜索路径：上⼀步切换到C/C++ Complier->Preprocessor->Additional include directory: ( one per line)10,选择调试器：切换到Debugger->Driver选择ST-Link->OK现在开始编译拍错1，右键main.c->Comliper会提⽰保存workspace，按提⽰操作，编译中会提⽰没有定义Fatal Error[Pe035]: #error directive: "Please select first the target STM8S/A device used in your application (in stm8s.h file)" C:\Documents and Settings\Administrator\桌⾯\EWSTM8_turial\Libraries\STM8S_StdPeriph_Driver\inc\stm8s.h 65双击该条提⽰，⾃动定位到错误位置，表⽰没有定义单⽚机型号，定义上#define STM8S003F32，再次执⾏1，这次的提⽰变为Error[Pe020]: identifier "GPIOH" is undefined C:\Documents and Settings\Administrator\桌⾯\EWSTM8_turial\GPIO\GPIO_Toggle\main.c 54双击该提⽰，定位到错误位置，向上找到 #define LED_GPIO_PORT (GPIOH)将GPIOH改为GPIOD（STM8S003F3没有GPIOH这个IO）3，再次执⾏1，OK没有错误4，整体编译⼀遍：右击⼯程->Make.在编译过程中有⼀部分⽂件会报错，不要担⼼，这些是STM8S003F3中没有的资源，将报错的⽂件删除即可另外对固件库了解后，可以只添加需要的部分，⽐如这次使⽤的是stm8s_gpio.c,那么只添加stm8s_gpio.c就可以了5，删除不需要的，再编译：OK没有错误，没有警告下载并调试，1，将STM8核⼼板通过SWIM与ST-Link连接起来，注意线序2，将ST-Link连接到电脑，（在设备管理器中usb总线中会看到ST-link的相关信息）3，给stm8核⼼板加电4，点击IAR的Download and debug，点击Go。

ST单片机STM8S开发入门教程
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。

STM8S硬件电路设计注意事项
(西南办：028-8626 9815 015208108068)
STM8S 可以不需要晶振跟复位电路，但是为了最小系统能够稳定运行，所以最好增加 外部电路。 注意事项
(1)VCAP 电容引脚(STM8S103PX 是第 8 个管脚)： STM8S 的 VCAP 管脚上的电容是一 个很特别的电容。它是 STM8S 的内核的工作电压。需要在外 部加一个外部的电容，以保 证内核工作电压的稳定。一般推荐 1uF 的瓷片电容。而且 1uF 的瓷片电容在进行 PCB 布线 时，必须要尽可能地靠近 VCAP 引脚，一直靠近到不 能再靠近为止。这一点非常非常重要， 切记！切记！（STM8L 系列上没有此电容）
(西南办：028-8626 9815 015208108068) 2、STM8 复位电路设计
STM8 单片机内置上电复位(POR)，所以，STM8 单片机可以不设外部上电复位电路， 依然可以正常复位，稳定工作。 若是系统需要设置按键复位电路，那么注意，STM8 单片 机是低电平复位，如下图，设计按键复位电路：
只有一对。 注意：建议将VDD/VSS引脚旁的VDD_IO/VSS_IO与其连接到一起并且只使用一个退耦 电容。目的是减少VDD/VDD_IO 与电容的引线长度，以达到良好的噪声性能。 一对VDDA/VSSA (3.3 V ± 0.3 V to 5 V ± 0.5 V)，专为模拟部分供电

最小系统设计：建立一个STM8 最小系统必须要有以下几部分：
电源 复位电路 时钟 仿真与调试接口：SWIM（Single wire interface module，单线接口模块）连接 1、电源 芯片需要外部提供3.0V 到5.0V 的稳定电源。芯片内部的电源管理系统在正常工作和低 功耗模式下为内核提供1.8V 的参考电源。芯片能够监测外部(3V/5V)和内部（1.8V）电源掉 电。 芯片提供： 一对VDD/VSS 引脚(3.3 V ± 0.3 V to 5 V ± 0.5 V)，连接到内部稳压参考电源 两对VDD_IO/VSS_IO (3.3 V ± 0.3 V to 5 V ± 0.5 V) ，专为I/O 供电。在32脚封装上，
