Reads a complete set of calibration constants for the analog input and output channels from the
Smart Star flash memory on the CPU card. These should be set using the
anaInCalib
or
anaInEERd
function, then saved to flash memory using the
anaSaveCalib
function.
Return Value
None.

Used to recalibrate the response of the A/D converter channel as a linear function using the two
conversion points provided. Gain and offset constants are calculated and placed into the global
table
_adcCalib
.
Parameters
channel
is the A/D converter input channel (0–10).
channel
should be passed as
channel = (slotnumber * 128) + (channelnumber)
where
slotnumber
is 0–6, and
channelnumber
is 0–10
or
channel = ChanAddr(slotnumber, channelnumber)
where
slotnumber
is 0–6, and
channelnumber
is 0–10.
value1
is the first A/D converter value.
volt1
is the voltage corresponding to the first A/D converter value.
value2
is the second A/D converter value.
volt2
is the voltage corresponding to the first A/D converter value.
Return Value
0 if successful, -1, if not able to make calibration constants.
