I am working in a project where ATMega32A Microcontroller(without any external crystal) is used with RFID RC522 and 1602A LCD Display. Programmer used USBasp.
using Atmel Studio 7.0 for compilation and avrdude in DOS prompt for transferring the hex file to ATMega32A.
From Internet I got MIFARE-RFID-with-AVR-master and utilised the same with required modifications.
What I find is that mfrc522_init(); is not giving the desired output, it is giving 0x00 and unable to detect the Reader.
If I bypass mfrc522_init(); then it is detecting the version of the RFID.
Any guidance / help will be highly appreciated.
