Basic STM32 library for STR25R chips (SPI) without RFAL
Project is HAL compatible, but is configured for NUCLEO-H7A3ZI - https://www.st.com/en/evaluation-tools/nucleo-h7a3zi-q.html
You can adapt it for others, but be careful with flash configuration for trace backup.
At this time:
X-NUCLEO-NFC05A1- https://www.st.com/en/ecosystems/x-nucleo-nfc05a1.html (no emulation, max SPI @ 6 MHz)X-NUCLEO-NFC06A1- https://www.st.com/en/ecosystems/x-nucleo-nfc06a1.htmlX-NUCLEO-NFC08A1- https://www.st.com/en/ecosystems/x-nucleo-nfc08a1.htmlX-NUCLEO-NFC12A1- https://www.st.com/en/ecosystems/x-nucleo-nfc12a1.html- ...
After many tests, many wires, many problems, many probes, etc... I created a minimal shield to experiment ST25R relaying with - not expensive - X-NUCLEO-NFC boards.
Schematic is very simple, you can find the project at: https://oshwlab.com/gentilkiwi/kst25r3916
