"EEPROM verify fail is usually associated over writing your code in your program or the EEPROM could be damaged. If you could provide any details on your code and circuit, that might help us determine the problem.

I'm trying to get an H-Bridge to work (BEAM's H-Bridge) using 2 x PNP and 4 x NPN I hope the EEPROM isn't dead http://forums.parallax.com/images/smilies/cry.gif

Disconnect your H-Bridge and try again. You may have a circuit error that is causing a programming problem.

Can you post your code as well as a schematic you are using?

I did what Jon said but 'EEPROM verify failure' as I did the test there was only this for code




' {$STAMP BS2}
' {$PBASIC 2.5}


DEBUG "Program Running!", CR

END



and no Schematic but for the H Bridge look at it here (http://www.solarbotics.net/library/circuits/driver_tilden.html)
and look at the one on the right

What was your previous code? Did you build the circuit exactly as shown? I had a tough time finding the link that you posted, I'm not sure if anyone else found it?

My previous code was




A Con 15
B Con 14

DO

HIGH A
PAUSE 1000
LOW A
HIGH B
PAUSE 1000
LOW B

LOOP
