Newbee What is missing? hpwm still won't compile in pbp syntax errors

16F877 at 4 mhz


Begin:

PVAL = 1000 ' Start with 1kHz
For Duty = 64 to 250
HPWM 1,Duty,PVAL
PAUSE 100
NEXT Duty

Duty = 127 ' 50% Duty-cycle
For PVAL = 1000 to 10000 step 100 ' Increments of 100. Change as needed
HPWM 1,Duty,PVAL
PAUSE 100
Next PVAL

GOTO Begin

END

You have to define your oscillator:

DEFINE OSC 4

Then you have to define PVAL and DUTY:

PVAL VAR WORD
DUTY VAR BYTE

Add these to the top of your program and try it.
