Hallo habe folgendes mini prog um pwm zu testen
um die funktion zu prüfen will ich eine LED angeschlossen an PINd.7
synchron zum OC1a steuern
PWM -Ausgang geht ,LED -Port hat 0V
WARUM????
Code:
$regfile = "m168def.dat" ' specify the used micro
$crystal = 16000000 ' used crystal frequency
$baud = 9600 ' use baud rate
$hwstack = 32 ' default use 32 for the hardware stack
$swstack = 32 ' default use 10 for the SW stack
$framesize = 64 ' default use 40 for the frame space
Config Pind.7 = Output
Config Pind.6 = Output
Config Pinb.1 = Output
Config Pinb.2 = Output
Config Timer1 = Pwm , Pwm = 8 , Compare A Pwm = Clear Up , Compare B Pwm = Clear Up , Prescale = 8
Compare1a = 150
Compare1b = 150
Do
Portd.7 = Portb.1
Portd.6 = Portb.2
Loop
