I use
IC prog
JDM (COM port DB9)
Win XP
16F628
Mine just doesn't work. I get error messages like "Verify failed at 0000h" or if I tried to blank check, I get "the device NOT blank at 0000h"
I did some research, and can voltage (MCLR and Vdd) be a problem?
I heard that MCLR should be over 13v, but what about Vdd?
Also, if the voltage is the problem, what should I do? I really don't have the money/time to buy or build another programmer.
Thanks.
PS. If I use Internal Osc., I don't have to have an external crystal, right?
