RT-Thread 学习笔记（三）——读取MCU ID及FLASH大小

突然想读一读MCU的识别ID号和FLASH大小，那就写一写呗！

型号：stm32f103zet6

根据datasheet知道相应的内容存储地址：

 

 然后就贴代码：

void rt_show_mcu_id(void)
{
    unsigned int mcu_id[3];
    unsigned short mcu_flash_size;

    mcu_id[0] = *(unsigned int*)(0x1FFFF7E8);
    mcu_id[1] = *(unsigned int*)(0x1FFFF7EC);
    mcu_id[2] = *(unsigned int*)(0x1FFFF7F0);
    rt_kprintf("MCU ID: %X %X %X\n",mcu_id[0],mcu_id[1],mcu_id[2]);
    mcu_flash_size = *(unsigned short*)(0x1FFFF7E0);
    rt_kprintf("MCU Flash size: %d K\n",mcu_flash_size);
}

调用这个函数就可以了！

 

完工！！！
