EUREKA!
Thanks guys! You have been a huge help. I have finally figured it out.
My problem was more like 3 problems...

1. I have never done EEPROM stuff before so I was lost to begin with.

Ok, get this! I just tried using a 16F84A instead of the 16F628A using nearly the exact same code and it works! I just removed the CMCON = 7 and DEFINE OSC 20 and stuck a 4MHz resonator on the...

I already have the "Program/Verify Data" option checked. Also if I Read the chip after Programming it, I do see the EEPROM data present in the Data EEPROM window. So it's definitely writing to the...

I have simplified my program to isolate the issue. I believe it lies with the READ command. This is my simplified code.



CMCON = 7
DEFINE OSC 20

No luck. I replaced the T2400 with 396 and it made no difference. I don't believe that the serial input is the problem because I can debug with a serial LCD and I can get it to print the actual ...

I am trying to make an RFID reader using Parallax's RFID Reader Module and a PIC 16F628A.
I am using PBP and am having troubles figuring out how to convert over the sample code found at Parallax to...
