1.设置工程时，如果忘记了在C/C++选项卡上设置STM32F10X_HD,USE_STDPEFIPH_DRIVER编译时会报如下的错误 Build target 'USART' compiling stm32f10x_it.c... ..\Libraries\CMSIS\CM3\DeviceSupport\ST\STM32F10x\stm32f10x.h(96): error: #35: #error directive: "Please select first the target STM32F10x device used in your application (in stm32f10x.h file)" ..\Libraries\CMSIS\CM3\DeviceSupport\ST\STM32F10x\stm32f10x.h: #error "Please select first the target STM32F10x device used in your application (in stm32f10x.h file)" ..\Libraries\CMSIS\CM3\DeviceSupport\ST\STM32F10x\stm32f10x.h: ^ ..\Libraries\CMSIS\CM3\DeviceSupport\ST\STM32F10x\stm32f10x.h: ..\User\stm32f10x_it.c: 0 warnings, 1 error compiling main.c... ..\Libraries\CMSIS\CM3\DeviceSupport\ST\STM32F10x\stm32f10x.h(96): error: #35: #error directive: "Please select first the target STM32F10x device used in your application (in stm32f10x.h file)" ..\Libraries\CMSIS\CM3\DeviceSupport\ST\STM32F10x\stm32f10x.h: #error "Please select first the target STM32F10x device used in your application (in stm32f10x.h file)" ..\Libraries\CMSIS\CM3\DeviceSupport\ST\STM32F10x\stm32f10x.h: ^ ..\Libraries\CMSIS\CM3\DeviceSupport\ST\STM32F10x\stm32f10x.h: ..\User\main.c: 0 warnings, 1 error compiling core_cm3.c... compiling system_stm32f10x.c... ..\Libraries\CMSIS\CM3\DeviceSupport\ST\STM32F10x\stm32f10x.h(96): error: #35: #error directive: "Please select first the target STM32F10x device used in your application (in stm32f10x.h file)" ..\Libraries\CMSIS\CM3\DeviceSupport\ST\STM32F10x\stm32f10x.h: #error "Please select first the target STM32F10x device used in your application (in stm32f10x.h file)" ..\Libraries\CMSIS\CM3\DeviceSupport\ST\STM32F10x\stm32f10x.h: ^ ..\Libraries\CMSIS\CM3\DeviceSupport\ST\STM32F10x\stm32f10x.h: ..\User\system_stm32f10x.c: 0 warnings, 1 error compiling stm32f10x_usart.c... ..\Libraries\CMSIS\CM3\DeviceSupport\ST\STM32F10x\stm32f10x.h(96): error: #35: #error directive: "Please select first the target STM32F10x device used in your application (in stm32f10x.h file)" ..\Libraries\CMSIS\CM3\DeviceSupport\ST\STM32F10x\stm32f10x.h: #error "Please select first the target STM32F10x device used in your application (in stm32f10x.h file)" ..\Libraries\CMSIS\CM3\DeviceSupport\ST\STM32F10x\stm32f10x.h: ^ ..\Libraries\CMSIS\CM3\DeviceSupport\ST\STM32F10x\stm32f10x.h: ..\Libraries\STM32F10x_StdPeriph_Driver\src\stm32f10x_usart.c: 0 warnings, 1 error compiling stm32f10x_gpio.c... ..\Libraries\CMSIS\CM3\DeviceSupport\ST\STM32F10x\stm32f10x.h(96): error: #35: #error directive: "Please select first the target STM32F10x device used in your application (in stm32f10x.h file)" ..\Libraries\CMSIS\CM3\DeviceSupport\ST\STM32F10x\stm32f10x.h: #error "Please select first the target STM32F10x device used in your application (in stm32f10x.h file)" ..\Libraries\CMSIS\CM3\DeviceSupport\ST\STM32F10x\stm32f10x.h: ^ ..\Libraries\CMSIS\CM3\DeviceSupport\ST\STM32F10x\stm32f10x.h: ..\Libraries\STM32F10x_StdPeriph_Driver\src\stm32f10x_gpio.c: 0 warnings, 1 error compiling stm32f10x_rcc.c... ..\Libraries\CMSIS\CM3\DeviceSupport\ST\STM32F10x\stm32f10x.h(96): error: #35: #error directive: "Please select first the target STM32F10x device used in your application (in stm32f10x.h file)" ..\Libraries\CMSIS\CM3\DeviceSupport\ST\STM32F10x\stm32f10x.h: #error "Please select first the target STM32F10x device used in your application (in stm32f10x.h file)" ..\Libraries\CMSIS\CM3\DeviceSupport\ST\STM32F10x\stm32f10x.h: ^ ..\Libraries\CMSIS\CM3\DeviceSupport\ST\STM32F10x\stm32f10x.h: ..\Libraries\STM32F10x_StdPeriph_Driver\src\stm32f10x_rcc.c: 0 warnings, 1 error Target not created
2.要注意新建工程包含库文件的路径是 \Libraries\STM32F10x_StdPeriph_Driver\inc 而不是 \Libraries\STM32F10x_StdPeriph_Driver\src
3.Overlapping of Algorithms at Address 08000000H错误 
工程设置里，误多添加了下载算法，删除后即可。 
//============================================================================================ 备注:: 1>今天烧写STM32遇到一个新问题----出现data not matching at address 0x80000000，最后把问题找到是烧写的串口线出了问题 ，导致烧完程序再读回验证出了问题。
