STM32 door lock password problem

The answer part of the reference to GPT, GPT_Pro better solution to the problem
STM32 code lock is a kind of security control for a lock, Usually, this kind of lock is controlled by a string of numbers(password) entered by the user. In actual use, if the correct input code is displayed but the correct password is displayed, it is likely that there is something wrong with the password setting, or it is caused by the failure of initialization.

First of all, we can check whether the code is wrong, such as the initialization function is written wrong or the code has a bug, of course, we can also check whether the pin used is properly connected, whether there is a break in the pin or whether there is debris on the pin. If none of these are the cause, try reburning the code and see if you can fix the problem.

Alternatively, you can try to reset the password, for example, to 111111 before initializing the password. It is also possible to reset the password because sometimes the password may change after an initialization failure or after a power-on.

Finally, you can also try using the serial assistant to look at the STM32's real-time data and compare it with the code so that you can find the problem.

// 这里是重新设定密码的代码
// 将密码重新设定为111111
char password[]="111111"; 
// 将密码传递到宣码锁上 
SetPassword(password); 
// 重新进行初始化操作 
Init();
