Hi,
can someone tell me, if it is possible to connect to the esp32 A1S using the SPI bus the card reader module RC522. The schematic can be found here: http://wiki.ai-thinker.com/_media/esp32 ... .2_sch.pdf
So far, I was not able to get the github code from https://github.com/abobija/esp-idf-rc522 running. I use following pins start_args{.miso_io = 18,.mosi_io = 23,.sck_io = 19,.sda_io = 22,}, which are specified according to the schematic sheet as IO. However, I am wondering that those pins overlap with the ones used for the KEYs mounted on the board.
Thanks for all your help!
