EASYPIC4 Board Giveaway

[Demon]

I just saw this contest now.


<---- darn tag under my name...

That is a very nice experiment board. I've been using the Lab X1 lately.

I thought the GLCD was misplaced but I found it so the development board is like in the 1st. post. It comes with a PIC18F4620 - you can use any PIC16F or PIC18F in 40, 28, 20, 18, 14 and 8 pin DIP packages. I installed a ZIF socket in the 40-pin position.

If anyone is interested, I have a PDF of the manual (it is too large at 2.5MB to upload).

Oh! The prize gets even better. Is anyone working on this contest? I hate to see a great prize and contest not even attempted!

Looks like nobody else, besides yourself, has any interest in this. So post your solution and lets see if you are the winner.

[cncmachineguy]

you have shamed me into it. LOL!

I am putting it together now, likely I will slide in just under the april 30 deadline.

Heres my code so far. It appears to work as needed, but thus far I have only tested it with a sim. I will try and put the hardware together tonight and test it in real time.

All comments welcome. I did this all software (no hardware PWM) as I thought it would be more fun.

Thanks for the contest RMTEO! Sorry I seem to be the only one entering.

[rmteo]

Yes, it will be interesting to see how it works!
