pn532 rfid module via i2c is not working
Posted: Fri Oct 12, 2018 1:57 pm
hi,
I'm trying an NFC pn532 module via i2c and getting ESP_ERR_TIMEOUT
BTW, I also tried Kolban's i2c scanner with the same result.
also, i'm using esp-idf v3.1
using the i2c with an oled display works.
so any help?
thanks,
danny
