| read 10 bit ADC on PIC16f876 |

Dear all,
Does anyone have an example of how to use the 10 bit adc on PIC16f876? Previously, I am using the ADC, but instead of 10 bit, I only read 8 bit. May I know how does the program look like, if I want to read all the 10 bits? Thanks.

For devices that do have the 10-bit resolution in the A/D, you simply type the following statement at the top of your .c file:
| Code: |
#include <18F2620.h>
#device ADC=10
#fuses MCLR,HS,WDT4096,NOPROTECT,NOLVP,NOXINST,PUT
...

Above, my statement ADC=10 means i want to use 10-bit A/D. If you wanted to use 8-bit A/D, then type ADC=8

If you want to make an A/D reading, you would store it in an "unsigned long" or int16:
| Code: |
unsigned long this_reading; // assumes ADC=10
this_reading = read_adc();
~~~~~~~~~
unsigned int this_reading; // assumes ADC=8
this_reading = read_adc();
