I've recently started to try and integrate PN532 NFC/RFID module with the STM32F469I-disco. I had tried to use a few libraries from git but no luck in making them work. As a fresh coder and embedded engineer, any leads or advice on how I can do this? Thx!

"As a fresh coder and embedded engineer, any leads or advice"

In that case, this may be a rather ambitious project?

Before this, have you covered the basics:

Using libraries does require that you spend some time understanding how to use them.

What, exactly, did you try? And what problems did you encounter?

What debugging did you do to try to find the problems?

I have been mostly working with Touchgfx now for almost 5 months and the goal now is to read different NFC/RFID cards using the PN523 and display them in a list on the touchscreen.

"What, exactly, did you try? And what problems did you encounter?"

I used the pn532-lib-master (https://github.com/soonuse/pn532-lib) and after changing pins and implementing it to the STM32F469I-DISCO, upon running the code the screen goes black, which I'm guessing is an RTOS issue but I don't know how to solve.

@Amaresh​ "I'm guessing is an RTOS issue"

Don't just guess!

You have a hypothesis - that it's an RTOS issue - so investigate that to see whether or not it is the case..

From the previous link: http://www.8052mcu.com/faqs/120313

Have you tried getting the NFC to work alone - without the added complications of an RTOS?
