PIC16F7X

The following steps should be followed for doing an

A/D conversion:

Configure the A/D module:

• Configure analog pins, voltage reference,

and digital I/O (ADCON1)

• Select A/D conversion clock (ADCON0)

• Turn on A/D module (ADCON0)

Configure the A/D interrupt (if desired):

• Clear ADIF bit

• Set ADIE bit

• Set PEIE bit

• Set GIE bit

Select an A/D input channel (ADCON0).

Wait for at least an appropriate acquisition

period.

Start conversion:

• Set GO/DONE bit (ADCON0)

Wait for the A/D conversion to complete, by

either:

• Polling for the GO/DONE bit to be cleared

(interrupts disabled)

• Waiting for the A/D interrupt

Read A/D result register (ADRES), and clear bit

ADIF if required.

For next conversion, go to step 3 or step 4, as

required.
