connecting ttgo t-display to Rc522 #508

Closed itbetters closed 4 years ago

itbetters commented 4 years ago

Hello I'm trying to connect the ttgo module to a MFRC522 rfid module . first I decided to use the miguelbalboa library but noticed that there is no hardware SPI pins on the TTgo module (since there are connected to the LCD as I think) then I found another which I think that would work since we can define software SPI pins there . but when compiling it displays an error for the "application.h" which is "error compiling for ttgo " . could you please guide me how I can use rc522 with ttgo board? regards

I think SPI bus is used by display and no way to connect a second device. I'm working on it for days but unfortunately seems impossible.
