38Khz IR carrier - best way to turn it on and off

[andywpg]

If you look in the manual under HPWM. You can see that pbp HPWM is only 8bits.
In your code you have the duty set at 254, which is nearly 100%. I think you would want to set
the duty to 50% or 127.

Wow! You are SO right - looks MUCH better now. Thanks!



Still has that slope on it though. I might try DT's Instant Interrupts and use a pin on and off to get it. Here's what the code is now:

HPWM 1, 127, 38000
MAIN:
        pauseus 1000
        trisc.2 = 1
        pauseus 1000
        trisc.2 = 0
	GOTO MAIN
