USB U2 Not programming ?

[Demon]

Maybe voltmeter on Lab X2 transformer jack to make sure it's working?

Are there other chips installed on Lab X2 that might interfere?

My power supply is from a regulated filtered 3A 12v Omron
LAB_x hase a 7805 regulator
chip has 5 v power
Jack is working, led is on !
Are there other chips installed on Lab X2 that might interfere?
No no other chips are installed.


The only reason I switch to the 16F877 was because I have one
and I installed it in the meLab LAB-x2 board

I want to make sure everything is from meLab and hopefully works
together including there program samples.

U2 programer, cable, LAB-X2 board , recommended PIC chip,
and there sample software (blink3x2) .
