野火stm32f4讀寫內(nèi)部flash程序按字，按半字，按字節(jié)

參考野火給的程序移植而成，需要的可以下載來使用，代碼已經(jīng)調(diào)試好，打開串口助手查看結果

單片機源程序如下:

#include "stm32f4xx.h"
#include "./usart/bsp_debug_usart.h"
#include "./led/bsp_led.h"
#include "./internalFlash/bsp_internalFlash.h"
void delay(unsigned int x)
{
while(x--);
}
/**
* @brief 主函數(shù)
* @param 無
* @retval 無
*/
int main(void)
{
unsigned int m;
uint32_t aa[2] = {0x12345678,0x11111111};
uint32_t bb[2] = {0};
uint16_t aa1[5] = {400,500,600,700,800};
uint16_t bb1[5] = {0};
uint8_t aa2[10] = {0,1,2,3,4,5,6,7,8,9};
uint8_t bb2[10] = {0};
/*初始化USART，配置模式為 115200 8-N-1*/
Debug_USART_Config();
LED_GPIO_Config();
LED_BLUE;
/*調(diào)用printf函數(shù)，因為重定向了fputc，printf的內(nèi)容會輸出到串口*/
