ADC=16 or ADC=10
PostPosted: Tue Sep 12, 2006 12:25 pm     Reply with quote
I am using a 18f458, that has a 10 bit adc
The questions is :
What i have to use ....ADC=16 ????
or adc=10?
I dont understand why the compiler allow me to put a 16 bit adc if i have only 10 bit in the hardware....
Thanks!

If you have a 10-bit ADC and you use ADC=16, the result will be
left-justified, as shown in the chart in the read_adc() section of the
manual. Link to CCS manual:

The chart is also shown in this post:
