Hello everybody and thanks always.
Since this year I am using the Pickit3 and I find it great specially for on board programming and debugging.
However today I found something curious that puzzle me and would like to hear your expert advice and experience.
I am using a PIC182550. The pickit PGD and PGC connects to the ports B7 and B6 (PGM although not used correspond to B5)
I wrote a program where I turn on and off pins B0~B3. No problem with that.
The thing is I am trying to use pins B4 and B5 to light LEDs. B4 works but B5 does not work.
I change my program (thinking maybe that my pin is damaged) to light LEDs through ports B6 and B7. Then none of the pins worked anymore.
(when you debug the program you can see that they work as they should, but once you program it in not-debug mode they dont work anymore)
I stopped using B6 and B7 and pins B0~B4 started working again.
Conclusion: When using PicKit3 you can not program the pins that it uses for PGD PGC and PGM! Ergo it is a waste of three useful pins!
Does anyone have a similar experience??
