Alright, thanks, so it's not a current problem. I should have known that.

As for the NOLVP, I have that fuse set.

I'm not sure of the problem, I'll have to try some other stuff out.

I have a PIC16F877A that I have working code for, but when I expand the code to use more inputs (nothing is really different as far as the computation goes), the PIC does nothing. I have 20 inputs go ...

Ok, I got it working. I just pulled everything out of my protoboard and re-attached it with my same code. Musta been some sort of messed up connection.

Thanks for all the help.

Still not getting any luck... maybe it has to do with my external oscillator? It's peak to peak voltage is only 2V...

Thanks for the reply. I am using a protoboard with a 5V DC power supply (one of the big hulking bench supplies that I have at my university). I have two 0.1uF capacitors connected from Vdd to ground ...

To me, it seems like the program isnt even starting for some reason. I have the command port_d=0 right at the beginning of main, and the outputs are 5V always, not matter what I do.

Ok, point taken about the switches, but will my method of switching work consistently too?

What do you mean? The input is just wired to a normal switch that chooses between a 5V source and ground.

Oh, and I am ctempel2. I forgot to log in when I posted.

I am doing a project which requires timed pulses that output to four motors, each corresponding to a different color of paint (the pulses will make a linear motor move back and forth to cover and unco ...
