Porting of RFAL Library to STM32F051

[PSchm]

Hi

I am using the ​NFC5 V1.3.0 for the STM32L053R8-Nucleo as an example to port the RFAL library for using with either a STM32F051 or STM32G071.

I replaced the Systick/NVIC/EXTI/GPIO/SPI Hal and everything seems to work, except that when I want to read out the UID of the used tag NFCV-15693 only 5 Bytes are read from the FIFO. On the Nucleo-Board the detection works fine.

Do you have any idea where my problem is?

Attached is the SPI communication with the not working MCU.

Thanks in advance.

Best regards

Patrick

​I fixed the problem which was related to the SysTick Timer.
