Mikroe Easypic PRO V7 development board issues

[leftek]

Hello,
i have one Mikroe Easypic PRO V7 development board and i have some issues with it.
I have observe some problems that make me to lose my trust and continue on it.
- some led's that not work
- some buttons that don't contact smooth
- sometimes after restart don't have stable running and i re-programming it

The question is if someone has general problems with these boards. Problems that make yourself to doubt about stable of it.

I have many MikroE development boards, and have NEVER had a single LED fail on any board.

Run the "LED curtain" example program with the supplied PIC18F87K22 PIM. All but 3 LEDs will flash (and 3 more LEDs that are not fitted)

LEDs for RG6, RG7, RF0 will not light - this is normal.

I have had buttons that are intermittent on older v6 boards, but not EasyPIC pro v7, which I have owned for many years and still works perfectly.

Test switches (and the 3 remaining LEDs) by setting all button press levels to Vcc, turning on all LEDs, hold down reset with one finger, press each button in turn with finger from other hand.

Should you find an intermittent button, press it hard many times and it may come back to life.

.... Unless you are talking about button bounce, which is normal and requires software debounce techniques.

Yes you are right. The mistake was mine. I have adding in code delay 500ms after the pressing of button and it's ok now.

Thank you.

I have this board too and have had no problems with it whatsoever. It’s been very stable and solid.

With regards to LEDs not lighting, are you sure the ports you’re driving them with aren’t in analog mode? That’s the default for some GPIO ports and you have to clear bits in the ANSELx register to make those ports digital outputs.

I have not seen the instability issues after a reset that you have. Are you using one of the MikroE tools or MPLABX? Are you using the built-in debug hardware or a PICkit or ICD3/4?

I had use that with MikroE and built-in programmer.
I don't know where is the problem.

Hi, have you contacted microelectronika regarding the problem?

Hello, no i have't yet, but i must to record it and send to him.
