I do have the pic I am attempting to use present.

I am attempting to build a project and am getting the error "Registration File error" "PCM: compiler not found"

When I change my

#include <16f18857.H>

from the corr ...

I needed to add in the NOEXTOSC fuse, that seems to have fixed the issue. Thanks to those of you that mentioned fuses you were totally on the right track.

I don't think its as simple as a pinout issue. I have tried changing the pinout between 6, 7, and 9 ( 7 being the logical one and 6 and 9 coming from the data sheet).

It's entirely possible that ...

changed that... still no luck. It has changed however, now it is hovering at zero as its readout.

So, I was working on some code and needed to get an analog input signal. I have done this several times, with no issues.... however this time it seems to be a bit different. What am I missing? I am ...

Everyone,

I finally got a working code. A bit strange as, so far as I can tell the ext_int_edge command is not working properly on this chip. So, I decided to change the bits manually and with a ...

Okay fixed that. Still no change but certainly good to get it right.

1. its primary job is really to do this interrupt. Everything else is secondary and not all that time sensitive (it only needs to go as fast as a human for display and stuff). So how fa ...

Okay so an update on what I have been doing. I was thinking about it last night and realized exactly what you pointed out with the edge... duh I need those. Anyway, I took your suggestion and stripp ...

So an update.... I was going back to the basics and found an interesting issue. When I run this external interrupt module where "inputsignal" is my 0-5v waveform it will never get into the ...

I have the delays in there to use as break points for trouble shooting. The waveform and speed are to control when it executes full wave run format. I don't want it to trigger when speed is 0 (its o ...

I removed the global interrupt stuff (except the stop button to shut it off). No change with that.

I am aware that setting the edge doesn't enable it.

I did not use the zcd that is built in due to not wanting to tie in ac power into the pic. I have an external zcd chip that feeds in a very nice isolated 0-5v square wave that matches up well with th ...

The Voltage on the input is 0 to 5VDC
The Frequency is 60 Hz
