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 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
;select internal AGND
MOV ADCCON3,#25H
;select offset calibration,
;31 averages per bit,
;offset calibration
To calibrate device gain:
MOV ADCCON2,#0CH
;select internal VREF
MOV ADCCON3,#27H
;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
;select external AGND
MOV ADCCON3,#25H
;select offset calibration,
;31 averages per bit
To calibrate system gain:
Connect system VREF to an ADC channel input (1).
MOV ADCCON2,#01H
;select external VREF
MOV ADCCON3,#27H
;select offset calibration
;31 averages per bit,
;offset calibration
The calibration cycle time, tCAL, is calculated by the following
equation:
tCAL = 14 × ADCCLK × NUMAV × (16 + tACQ)
For an ADCCLK/fCORE divide ratio of 16, with tACQ = 4 ADCCLK,
and NUMAV = 15, the calibration cycle time is:
tCAL = 14 × (1/1,048,576) × 15 × (16 + 4)
tCAL = 4.2 ms
In a calibration cycle, the ADC busy flag (ADCCON3[7]),
instead of framing an individual ADC conversion as in normal
mode, goes high at the start of calibration and only returns to 0
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
