16f688 Adc

[Darrel Taylor]

Setting up the 10-bit ADC I expected a 0 – 1023 range, what I got was 0 to 65472 !!?

That's from the ADFM bit. For 10-bit A/D, use ADCON0.7 = 1 ; right justify

The math depends on what you're reading, but this might help ..

Thanks Darrel!

I changed the; ADCON0 = %00000001 to ADCON0 = %10000001, and it works!
And yes, the link helped me do some math too, only; how can I get two decimals?

Thanks again!

For 2 decimals, multiply by 500 instead of 50.

Then this will display the value with 2 decimal places ...

   LCDout $FE,2,"V= ",DEC Volts/100,".",DEC2 Volts//100," Vdc"
