I am trying to program a Raspberry Pi Pico with Arduino in order to control the ST25DV NFC chip. I want to use the stm32duino ST25DV library.
I have a question about the pin assignment in the ST25DV_HelloWorld.ino program.
I am using the ST25DV 8-pins package and according to the datasheet there is no LPD pin so I do not understand what pin to assign to the variable LPD_PIN in the program. I tried using the V_EH pin and assigning to LPD_PIN the corresponding pin of the microcontroller but this results in "System Init failed!" in the serial monitor.
I have searched in the stm32duino/ST25DV documentation but have not found anything relevant to this topic.
Can somebody help me with this issue?
