Perfect situation to learn/use MPLAB stop watch. That will teach you, at least, how PAUSEUS is acurate for a specific Xtal. You should have a look to that. Probing with a scope is also an option... for that, i'll prefer MPLAB stopwatch.

Ive been looking around the internet for info on the MPLAB stopwatch and I really have no idea what it is and how to use it. The most helpful thing I found was this code segment (posted by you, mister_e):

' Fine tuned with MPLAB StopWatch to get MainLoop = 1 sec
'
for delay=1 to 307
@ nop
next

Bruce give me a short explanation of it before i wrote those lovely lines

There's a few explanation in the MPLAB help-file too.

Ah Ive almost got it now. I downloaded MPLAB IDE v7.22 and loaded up the .asm file that picbasic pro compiled. I started the stopwatch and ran the program with MPLAB SIM as the tool but it just ends up saying "Time (mSec) 3.276800". How can I use it to measure the time between two points in my program?

My TV is NTSC.

The link below is about PAL and the main power frequency is 50 Hz.

I based my code on the ASM example given in that link. Since both PAL and NTSC use the same signal structure it should work on my TV. I dont have a vertical synch inserted so it just repeats the same thing (synch, pause, gray, white, gray) over and over again.

What is the video standard of your TV-set? (PAL or NTSC)
