INITIATING CALIBRATION IN CODE
When calibrating the ADC using ADCCON1, the ADC should
be set up into the configuration in which it will be used. The
ADCCON3 register can then be used to set up the device up
and calibrate the ADC offset and gain.
MOV ADCCON1,#0ACH
;ADC on; ADCCLK set
;to divide by 16,4
;acquisition clock
To calibrate device offset:
MOV ADCCON2,#0BH
MOV ADCCON3,#25H
;select internal AGND
;select offset calibration,
;31 averages per bit,
;offset calibration
To calibrate device gain:
MOV ADCCON2,#0CH
MOV ADCCON3,#27H
;select internal V
REF
;select offset calibration,
;31 averages per bit,
;offset calibration
To calibrate system offset:
Connect system AGND to an ADC channel input (0).
MOV ADCCON2,#00H
MOV ADCCON3,#25H
;select external AGND
;select offset calibration,
;31 averages per bit
To calibrate system gain:
Connect system V
REF
to an ADC channel input (1).
MOV ADCCON2,#01H
MOV ADCCON3,#27H
;select external V
REF
;select offset calibration,
;31 averages per bit,
;offset calibration
The calibration cycle time T
CAL
is calculated by the
following equation:

In a calibration cycle, the ADC busy flag (Bit 7), instead of
framing an individual ADC conversion as in normal mode, will
go high at the start of calibration and only return to zero at the
end of the calibration cycle. It can therefore be monitored in
code to indicate when the calibration cycle is completed. The
following code can be used to monitor the BUSY signal during
a calibration cycle:
WAIT:
MOV A, ADCCON3 ;move ADCCON3 to A
JB ACC.7, WAIT ;If Bit 7 is set jump to
WAIT else continue
