A/D CONVERSION PROCEDURE
This is an example procedure for using the ADC to
perform an Analog-to-Digital conversion:
1.
perform an Analog-to-Digital conversion:
1.
Configure Port:
• Disable pin output driver (Refer to the TRIS
• Disable pin output driver (Refer to the TRIS
register)
• Configure pin as analog (Refer to the ANSEL
register)
2.
Configure the ADC module:
• Select ADC conversion clock
• Select ADC input channel
• Turn on ADC module
• Select ADC conversion clock
• Select ADC input channel
• Turn on ADC module
3.
Configure ADC interrupt (optional):
• Clear ADC interrupt flag
• Enable ADC interrupt
• Enable peripheral interrupt
• Enable global interrupt
• Clear ADC interrupt flag
• Enable ADC interrupt
• Enable peripheral interrupt
• Enable global interrupt
(1)
4.
Wait the required acquisition time

.
5.
Start conversion by setting the GO/DONE bit.
6.
Wait for ADC conversion to complete by one of
the following:
• Polling the GO/DONE bit
• Waiting for the ADC interrupt (interrupts

7.
Read ADC Result.
8.
Clear the ADC interrupt flag (required if interrupt
is enabled).

Note 1:
The global interrupt can be disabled if the
user is attempting to wake-up from Sleep
and resume in-line code execution.
