fatfs

api这里有非常详细的介绍

这一部分需要自己实现 具体看代码MYfatfs ffconf,h点进如何配置？api以后也可以看到

int main(void) { 
           FRESULT ref;  LED_GPIO_Config(); // LED_BLUE;    /* 配置为115200 8-N-1 */  USART_Config();  printf("\r\n 这是一个8Mbyte串行flash(W25Q64)实验 \r\n");   //FRESULT f_mount ( //FATFS* fs, /* [IN] Filesystem object文件系统对象模块 */ //const TCHAR* path, /* [IN] Logical drive number */ //BYTE opt /* [IN] Initialization option */ //); //#define SD_CARD 0 //#define SPI_FLASH 1  ref = f_mount (&fsObject, "1:", 1);///挂载文件系统  printf("ref f_mount = %d\r\n",ref);  // 生成文件系统  if(ref == FR_NO_FILESYSTEM)  {
