is there a problem?

CodePudding user response:

1, the first initialization AT89C51 serial
2, looking for a mature AT89C51 on serial communication program
3, according to the communication protocol of MFRC500, communication subroutine to make appropriate changes to above
4, with a serial port debug elf debugging

This is easy
Involving less than what algorithm, only according to the process, step-by-step implementation of the can

The baidu should have information, Posting please others directly program is almost impossible to have other people give! Unless someone else is done like this project, otherwise is a program all have to think about to write, but also is not a general program!
