Hi,
I am failry new to this game and would appreciate some help if anyone can.
I am currently making an magnetometer which uses a 16F877-20 with 2 external eeprom chips. I have successfully made one but the second has caused me problems. For some reason on startup the PIC cannot see the EEPROM. Can anyone please tell me how the PIC communicates with the EEPROM and is there anyway I can check that it is functioning properly.
Any ideas would be appreciated.
Many thanks
