It's easy, just insert some line breaks:

-------
I have a spotlight controller made for a DJ booth. We are using it to
control spots for an animated band.

The problem is the controller has a "standby" button which turns the
spot array on and off. The unit defaults to "standby" when powered up.
This setup needs to be stand-alone.

What I need to do is program a PIC (I have a few 12F675's) to monitor
the audio stream and the "standby" LED signal (0-5v square wave, 50%
Duty Cycle. It flashes when in standby mode) and have the PIC toggle
the standby button (on-off momentary) when these conditions are
active:

- If there is no music and the standby LED is off then it should toggle it =
on.

- When there is music and the standby LED is on, it again should toggle it.

- "Do nothing" situations are Music on, LED off and Music off, LED on.

- In between songs if the controller is left out of standby mode then
the lights will take a random pattern.

- After all the songs are done the lights will also stay on in a
random number (it seems to latch on the last ones that are lit and
stays there).

There are 12 spot lights. Hence the need for toggling the button.

I was going to use the ADC of the 12F675 to detect the audio but from
the documentation, it says that won't work. I plan to use the
comparator (CMCON - CM0, CM1) to test for the LED status and the
comparator interrupt flag (CMIF) to indicate when the LED is on. Once
read I can reset the bit in the program. I could use some help in the
audio detection area. The audio signal is coming from the audio output
of a standard home DVD player. I haven't scoped it but I assume it's
in the area of a volt or so.

Also, one of our robots has eyes that can move side to side and the
small board that works the RC solenoid has a PIC chip on it, but it
doesn't work. The company that made these automatons, The Robot
Factory, has no idea what the program is for this PIC. It's just
supposed to move the eyes randomly side to side within a 90 degree
arc. Anybody know of a quick program that will accomplish this using
the '675??
