Automatic Toilet Flusher

I'm using a 16F627A

and yes, I've tried changing those numbers and I've tried using the numbers that Bruce posted, but I still get the same result regardless. I've also tried using a different servo (another parallax one)

So, you're running at 4Mhz (INTOSC). The PBP manual tells us that at 4Mhz, pulsout has a granularity of 10us. Your loop runs from 200 to 1200, meaning 2000us (2ms) to 1200 (12ms). A bit out of the range of a normal servo ya think? Unless you've got one of the oddball ones...

Also, try turning off the WDT and Brown-Out reset for grins... You might be killing the battery voltage when the servo tries to move and causing a reset.

Use GOSUB VS GOTO if the routine you're going to uses RETURN to get back.

Disable onboard comparators with CMCON=7 before trying to use a pin that
has the comparator feature.

Give this a shot;

@ __config _INTOSC_OSC_NOCLKOUT &_WDT_ON &_PWRTE_ON &_MCLRE_OFF &_BODEN_ON &_CP_OFF &_DATA_CP_OFF &_MCLRE_OFF


servo1 var Porta.0
x var byte
CMCON=7 ' <-- disable analog comparators

    low servo1
    HIGH PORTB.3
	
loop:	
    pause 500
    low portb.3
    pause 500
    high portb.3
    GOSUB move   ' <-- use GOSUB VS GOTO
    pause 2000
    low portb.3
    GOTO loop

move:
    for x = 200 to 100 STEP -1 ' 2mS to 1mS pulse
      pulsout servo1,x
      pause 18
    next x
    pause 2000
  		
    for x = 100 to 200 ' 1mS to 2mS pulse
      pulsout servo1,x
      pause 18
    next x
    pause 2000
    return
  		
   END

This should cycle your servo from one side to the other. Tested with a
Parallax servo.

Bruce, works beautifully, thank you!
