16f876a Pwm

Here's some code. Thanks for the help!!

@ device PIC16F876A, hs_osc, wdt_off, pwrt_off, bod_off, lvp_on, cpd_off

TRISA=%00000000
TRISB=%00000000
ADCON0=7
ADCON1=7

W VAR BYTE

TheLoop:

FOR W=1 TO 255
PWM PORTB.0,W,1
NEXT W

HIGH PORTB.0

PAUSE 1000

' As soon as I start this PWM on PORTB.1, PORTB.0 goes LOW...this is what I need to fix.

FOR W=1 TO 255
PWM PORTB.1,W,1
NEXT W

HIGH PORTB.1

PAUSE 1000

GOTO TheLoop

You don't seem to have the RBPU enabled in your code (OPTION_REG) and also you may not be having external pull ups on the PWM output pins. So, when the PWM code executes, it does the RMW routine and PortB.0 goes low. You could check on this.

That did the trick! Thank you so much!
