Hello Bruce,
Thanks for the info, I was really getting frustrated with the pot command and finding a proper value of a photo resistor to use.I found that the adc works great with just about any photo resistor value.
Also thanks TonyA and your right that the adc does work best for this type of application and it is very fast too, I'm pleased to see. I'm also using an 18f452 (great micro) but not with the ADCin command and it works great.
Once again thanks everyone for getting me kick started on this.Code:Check_The_Light_Level: adcon1=%00001110 ' AN0 analog, all other pins digital ADCON0 = $41 ' Set A/D to Fosc/8, Channel 0, On Pauseus 50 ' Wait for channel to setup ADCON0.2 = 1 ' Start conversion Pauseus 50 ' Wait for conversion Lite_Level = ADRESH ADCON1 = 7 ' shut off (Disable) ADC RETURN
Thanks
jessey
