ST25RU3993 RFID
PostPosted: Tue Jul 12, 2022 12:06 pm     Reply with quote

Looking for sample code to interface a PIC24FG processor to the ST25RU3993 RFID transponder chip. Any help is appreciated.

You'd have to get something like the ANSI reference library for this,
and adapt to your PIC:

I've not seen any PIC libraries for this.

Understand this requires a quite large operating stack, so a PIC with a
reasonable amount of ROM & RAM will be needed.
Glad to see you are talking about 3.3v processors. Makes the interfacing
a lot easier.

Ttelmah thanks for the links. I have those documents and am working through them. Just trying to find code that has already been written on the PIC. I'm more familiar with the PIC than with the ST processor. And that code is written for the ST processor as ST produces the RFID chip.

The main code should work. Obviously with #device ANSI.
The bits that will need work are the actual communication functions,
that will need to be custom for the PIC.
It is intersting that I wasn't able to see for example Arduino or Pi
code for this.
