Code programming error at 0000

JDM,

Did you ever replace that cable? M to F 25-pin, straight thru (not null-modem cable).

I would fix that FIRST. Even though the "hillbilly cable rig" works on some/most chips, the longer cable run might be a problem for others. Additional noise, voltage drop, etc.

I've just started getting this error too. I am using the MeLabs serial programmer on a 16F628A in circuit (which has a 0.1uF cap).

Odd, I can program a 18F2550 on the same circuit over and over again without any problem.

I have Erase Before Programming but I keep getting the same 0000 error. I must have tried at least 20 times just now.

I'll try soldering PGC/PGD real close to the PIC and see if the length of the leads (along with trace length) is at fault.

I've soldered PGC/PGD right at the 16F628A in-circuit with the same 0000 error.

I'm also using an external power supply for the circuit, the same supply I used when this was on breadboard.

I don't think this is a configuration problem either 'cause I made sure to breadboard this circuit beforehand. This was the 1st time I upgraded a 16F628 to a 16F628A and I wanted to be sure of the configuration settings.

Frustrating, and I'm sure it's not hard to fix this either...
