Hi,
I have an RFID reader (PN5180) and LCD (16x2) connected. I can print tag (iso 15693) on serial monitor like the UID. Result on screen: E0 04 01 50 D4 7E A0 CC. However I want to capture this data so I can use comparing it and displaying it on the LCD. The error I get on line: lcd1.print(uid[7 - i], HEX); is:
no matching function for call to 'LCDIC2::print(uint8_t&, int)'. Something to do with the HEX. Please advice. Thank you!!!!
