Message “Error trying to activate programmer …” ??

Hello people,

I am facing a problem while programming my PIC.

When i start the programming of my PIC i get a warning message shown below:

Warning

Error trying to activate programmer,
Can't drop PIC power supply voltage to enter into program mode.
 
                                       OK

It is constantly creating a problem for me. I tried to revert it back to its original state but of no use. It still keeps on giving me this message again and again. The program itself is running perfectly fine on the PIC in the beginning, and the blue LED light is also on but suddenly this warning appears again. I am using the USB device view tool, and it confirms my connection to the board.

The configuration is as follows:

EasyPIC6, mikroC PRO for PIC V5.40, PIC 16F887

Can anybody tell me what's the reason behind this problem? why i cant activate the programmer?

Waiting for your views…..

Regards,

Judi

For your situation try to remove the GLCD while programming although this is not convenient when developing GLCD application. You need also to engage the pull down on port B by using the SW2. GLDC used RBO to RB5. Engaging the pull down is good but it is also enough if you will do it only for RB3 or RB4. Try also to switch off all Sw9. In some situation you will need to order some different chips or 40 pin device that you may try and see if it will work. Just try all my suggestions above; also one thing that you can try is to disable vpp first mode entry see also if it will work for you.
