A humble request to anyone who can rewrite MFRC522 library to use UART imterface
cyberjupiter opened this issue · comments
Hi. I am not a skilled nor an experienced programmer. Even after looking at the datasheet, changing the current SPI interface to UART is totally beyond my level.
Therefore, I really hope someone will implement the MFRC522 library which uses UARt interface.
Is there any way to contact him? I am new to github and it seems to not have PM function.
Anyway, I will try to figure out what he did from his comments. There is so little information from his comments but I will give it a shot.
As I remember ,Framing in SPI is different with UART in MFRC522,datasheet completely described framing for each connection.Please read datasheet and if your problem does not resolved contact me via

Hi @Dizgah
Yes, I have read the datasheet and I can differentiate how data is sent between SPI and UART. However, I do not know how to implement it. As I have stated in my first post, my knowledge in programming is limited. If you have some examples that I could follow through, that would be helpful.
P/S: The problem is that the MFRC522 library uses SPI entirely. How do I modify which lines to use UART? And as far as I know, UART is a serial communication and in Arduino, there is no library for UART. You just use it. Thats why I am very confused.

@cyberjupiter Any update?
