ESP32-Lyrat SPI connections

Postby cmeineck » Fri Dec 14, 2018 3:15 pm

I am looking for guidance, i am trying out the ESP32-Lyrat development board, i want to connect a RFID reader using SPI bus. Looking at the board there does not seem to be any direct way of doing this. I was wondering if i could use the JTAG connector and/or any other connections , i realise i would not be able to use the JTAG for debugging etc .
Any help would be good.

Yes, you should be able to abuse the JTAG port for that. I recall I did that for an earlier Lyra board and it worked well.

Hi Chris,

I just wondered if you had any luck getting SPI working over JTAG pins ?
Did you have enough for CS pin to ?
