[size=13.3333px]如题,本来想用STM32F4的UID做个加密,读取UID,结果全FF,难道我买了假货?不应该啊,我在立创商城上买的,不能是假的吧。程序如下:
[size=13.3333px]static uint32_t id_code[3];
[size=13.3333px]void Read_UID(void)
[size=13.3333px]{
[size=13.3333px] id_code[0] = *( uint32_t *)(0x1ffff7e8);
[size=13.3333px] id_code[1] = *( uint32_t *)(0x1ffff7ec);
[size=13.3333px] id_code[2] = *( uint32_t *)(0x1ffff7f0);
[size=13.3333px]}
