库函数说明在lbdp.h中
#define LBDP_FUNC_ENTRY 0x8002B80
typedef void (*p_lbdp_remap)(void);
typedef void (*p_lbdp_writeFlash)(uint16_t addr,uint16_t writeFlashData);
typedef void (*p_lbdp_eraseFlash)(uint8_t page);
应用程序需要在main.c中声明如下:
#include "lbdp.h"
p_lbdp_eraseFlash ex_lbdp_eraseFlash;
p_lbdp_writeFlash ex_lbdp_writeFlash;
//p_lbdp_remap ex_lbdp_remap;
ex_lbdp_eraseFlash = (p_lbdp_eraseFlash)lbdp_map(2);
ex_lbdp_writeFlash = (p_lbdp_writeFlash)lbdp_map(3);
lbdp_map(int index)实现很简单:
uint32_t lbdp_map(int index)
{
return *(uint32_t*)(LBDP_FUNC_ENTRY +index*4); //本例中,库函数入口在LBDP_FUNC_ENTRY定义的flash中。
}
