答案对人有帮助，有参考价值 0 虽然stm32f10x系列使用的都是M3的内核，但是不同芯片的外设也不一致。所以拿到芯片后需要根据具体的芯片来选择相应的启动文件和建立工程，这里并不是通用的。在新建工程的需要选择相应的芯片型号，只选择对应的型号就可以吗？当然不是啦！在芯片复位后会调用system_stm32f10x.c中的SystemInit等函数时进行初始化。查看这个文件你会发现里面有很多条件补充，比如配置系统，时钟有为 24M 的，所以我们需要进行宏的定义。可以在代码中实现，可以在魔术棒里面配置。这样的话可能会编译和相关的程序也同样启动文件的选择也应该根据芯片存储空间的大小来选择，对于的关系图如下： ;****************** (C) COPYRIGHT 2011 STMicroelectronics ****************** ;* File Name : startup_stm32f10x_md_vl.s ;* Author : MCD Application Team ;* Version : V3.5.0 ;* Date : 11-March-2011 ;* Description : STM32F10x Medium Density Value Line Devices vector table ;* for MDK-ARM toolchain. ;* This module performs: ;* - Set the initial SP ;* - Set the initial PC == Reset_Handler ;* - Set the vector table entries with the exceptions ISR address ;* - Configure the clock system ;* - Branches to __main in the C library (which eventually ;* calls main()). ;* After Reset the CortexM3 processor is in Thread mode, ;* priority is Privileged, and the Stack is set to Main. ;* <<< Use Configuration Wizard in Context Menu >>> ;***************************************************************************** ; THE PRESENT FIRMWARE WHICH IS FOR GUIDANCE ONLY AIMS AT PROVIDING CUSTOMERS ; WITH CODING INFORMATION REGARDING THEIR PRODUCTS IN ORDER FOR THEM TO SAVE TIME. ; AS A RESULT, STMICROELECTRONICS SHALL NOT BE HELD LIABLE FOR ANY DIRECT, ; INDIRECT OR CONSEQUENTIAL DAMAGES WITH RESPECT TO ANY CLAIMS ARISING FROM THE ; CONTENT OF SUCH FIRMWARE AND/OR THE USE MADE BY CUSTOMERS OF THE CODING ; INFORMATION CONTAINED HEREIN IN CONNECTION WITH THEIR PRODUCTS. ;*************************************************************************** ; Amount of memory (in bytes) allocated for Stack ; Tailor this value to your application needs ; Stack Configuration ; Stack Size (in Bytes) <0x0-0xFFFFFFFF:8> ; Stack_Size EQU 0x00000400 AREA STACK, NOINIT, READWRITE, ALIGN=3 Stack_Mem SPACE Stack_Size __initial_sp ; Heap Configuration ; Heap Size (in Bytes) <0x0-0xFFFFFFFF:8> ; Heap_Size EQU 0x00000200 AREA HEAP, NOINIT, READWRITE, ALIGN=3 __heap_base Heap_Mem SPACE Heap_Size __heap_limit PRESERVE8 THUMB ; Vector Table Mapped to Address 0 at Reset AREA RESET, DATA, READONLY EXPORT __Vectors EXPORT __Vectors_End EXPORT __Vectors_Size __Vectors DCD __initial_sp ; Top of Stack DCD Reset_Handler ; Reset Handler DCD NMI_Handler ; NMI Handler DCD HardFault_Handler ; Hard Fault Handler DCD MemManage_Handler ; MPU Fault Handler DCD BusFault_Handler ; Bus Fault Handler DCD UsageFault_Handler ; Usage Fault Handler DCD 0 ; Reserved DCD 0 ; Reserved DCD 0 ; Reserved DCD 0 ; Reserved DCD SVC_Handler ; SVCall Handler DCD DebugMon_Handler ; Debug Monitor Handler DCD 0 ; Reserved DCD PendSV_Handler ; PendSV Handler DCD SysTick_Handler ; SysTick Handler ; External Interrupts DCD WWDG_IRQHandler ; Window Watchdog DCD PVD_IRQHandler ; PVD through EXTI Line detect DCD TAMPER_IRQHandler ; Tamper DCD RTC_IRQHandler ; RTC DCD FLASH_IRQHandler ; Flash DCD RCC_IRQHandler ; RCC DCD EXTI0_IRQHandler ; EXTI Line 0 DCD EXTI1_IRQHandler ; EXTI Line 1 DCD EXTI2_IRQHandler ; EXTI Line 2 DCD EXTI3_IRQHandler ; EXTI Line 3 DCD EXTI4_IRQHandler ; EXTI Line 4 DCD DMA1_Channel1_IRQHandler ; DMA1 Channel 1 DCD DMA1_Channel2_IRQHandler ; DMA1 Channel 2 DCD DMA1_Channel3_IRQHandler ; DMA1 Channel 3 DCD DMA1_Channel4_IRQHandler ; DMA1 Channel 4 DCD DMA1_Channel5_IRQHandler ; DMA1 Channel 5 DCD DMA1_Channel6_IRQHandler ; DMA1 Channel 6 DCD DMA1_Channel7_IRQHandler ; DMA1 Channel 7 DCD ADC1_IRQHandler ; ADC1 DCD 0 ; Reserved DCD 0 ; Reserved DCD 0 ; Reserved DCD 0 ; Reserved DCD EXTI9_5_IRQHandler ; EXTI Line 9..5 DCD TIM1_BRK_TIM15_IRQHandler ; TIM1 Break and TIM15 DCD TIM1_UP_TIM16_IRQHandler ; TIM1 Update and TIM16 DCD TIM1_TRG_COM_TIM17_IRQHandler ; TIM1 Trigger and Commutation and TIM17 DCD TIM1_CC_IRQHandler ; TIM1 Capture Compare DCD TIM2_IRQHandler ; TIM2 DCD TIM3_IRQHandler ; TIM3 DCD TIM4_IRQHandler ; TIM4 DCD I2C1_EV_IRQHandler ; I2C1 Event DCD I2C1_ER_IRQHandler ; I2C1 Error DCD I2C2_EV_IRQHandler ; I2C2 Event DCD I2C2_ER_IRQHandler ; I2C2 Error DCD SPI1_IRQHandler ; SPI1 DCD SPI2_IRQHandler ; SPI2 DCD USART1_IRQHandler ; USART1 DCD USART2_IRQHandler ; USART2 DCD USART3_IRQHandler ; USART3 DCD EXTI15_10_IRQHandler ; EXTI Line 15..10 DCD RTCAlarm_IRQHandler ; RTC Alarm through EXTI Line DCD CEC_IRQHandler ; HDMI-CEC DCD 0 ; Reserved DCD 0 ; Reserved DCD 0 ; Reserved DCD 0 ; Reserved DCD 0 ; Reserved DCD 0 ; Reserved DCD 0 ; Reserved DCD 0 ; Reserved DCD 0 ; Reserved DCD 0 ; Reserved DCD 0 ; Reserved DCD TIM6_DAC_IRQHandler ; TIM6 and DAC underrun DCD TIM7_IRQHandler ; TIM7 __Vectors_End __Vectors_Size EQU __Vectors_End - __Vectors AREA \|.text\|, CODE, READONLY ; Reset handler Reset_Handler PROC EXPORT Reset_Handler [WEAK] IMPORT __main IMPORT SystemInit LDR R0, =SystemInit BLX R0 LDR R0, =__main BX R0 ENDP ; Dummy Exception Handlers (infinite loops which can be modified) NMI_Handler PROC EXPORT NMI_Handler [WEAK] B .
