Hi there,
I'm a new user to the EPIC WIN software and previously thought I was successful in uploading a number of different programs from my windows XP computer to a PIC18F458 MCU using the software obtained from melab. However, after repeated use, I now encounter the error message: "code programming error at 0000", which, on checking the readme text information, refers to power supply issues to an actual programmer, or a low voltage pin not grounded. I grounded RB5 via a 100k resistor, unchecked the enable low voltage programming option, and the power supply to the board sits at the required 16VDc, but I notice the voltage on the MCLR pin is down to around 5V. I know this is the programming pin. What do you think could perhaps be causing this? Another thing, do you think modifying epic.ini as you have done, would assist my problem?
