pn532 rfid module via i2c is not working

Postby danny@cs.huji.ac.il » 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
