pickit2 clone problem with using PB.6 and PB.7 pins

[sresam89]

dear all
the problem i am facing is that what ever i try to connect with my PB.6 PB.7 pins it is not working.
the program and all other part and files are good working flawlessly, even the same(PB.6 PB.7 pins) is working while using a different programmer.what would be the problem/solution for this?
i know these two two pins are used for programming the IC. i use 16f877a. this was tested using both ICSP and normal IC in socket programming.

thanks in advance

Would you be able to post a schematic of your pickit 2 clone?

hi wills
actually i purchased it from a vendor. so i might not be able to putup a file for it, SORRY!
but right from start i have been having problems with the programming of PB.6,7 pins i recently only noticed it with programming my controller with a different one(TOPWIN2005+).
any other things i could share so u could help me?

Hi,

At least give us the maker / model number of the clone so we can get some idea of the unit.

Also what software does it use, Microchips or its own version ?


Just have to ask, you refer to the programing pins as PB.6 Pics are typically refered to as RB6 and 7 - you are not trying to program Atmel chips are you ?

Is the issue the use of pins RB6 and RB7 after the device has been programmed?


If so, it sounds like you may have Debugging enabled in the Configuration Register settings, which dedicates pins RB6 and RB7 to In Circuit Debugging (ICD).

Ensure you have disabling Debugging and Low Voltage Programming (LVP) in the devices Configuration Register Settings.
