對于需求STM32F0 IAP升級的朋友，這個例程不要錯過，足夠你在研發使用了

單片機源程序如下:

#include "stm32f0xx.h"
#include "main.h"
#include "delay.h"
#include "tim1.h"
#include "usart.h"
#include "iap.h"
#include "gpio.h"
uint32_t TimingDelay;
uint32_t Program_Addr1=0x8002000; //FLASH前8K直接給BootLoad
uint32_t Program_Addr2=0x8002400;
uint32_t Program_Addr3=0x8002800;
uint32_t Program_Addr4=0x8002C00;
uint8_t RX_Value;
int main(void)
{
uint32_t CNT;
// //void IAP_Set(void)
uint32_t i = 0;
/* Relocate by software the vector table to the internal SRAM at 0x20000000 ***/
/* Copy the vector table from the Flash (mapped at the base of the application
load address 0x08003000) to the base address of the SRAM at 0x20000000. */
FLASH_Unlock();
for(i = 0; i < 48; i++)
{
*((uint32_t*)(0x20000000 + (i << 2)))=*(__IO uint32_t*)(APPLICATION_ADDRESS + (i<<2));
}
/* Enable the SYSCFG peripheral clock*/
FLASH_Lock();
RCC_APB2PeriphClockCmd(RCC_APB2Periph_SYSCFG, ENABLE);
/* Remap SRAM at 0x00000000 */
SYSCFG_MemoryRemapConfig(SYSCFG_MemoryRemap_SRAM);
if (SysTick_Config(SystemCoreClock / 1000)) //1ms中斷一次
{
/* Capture error */
while (1);
}
while(1)
{
LED_Init();
STM32_USART_Init();
while(1)
{
GPIOF->ODR|=1<<7;
delay_ms(500);
GPIOF->ODR&=~(1<<7);
delay_ms(300);
if(RX_Value==0x05) GPIOB->ODR^=3;
}
}
}
