float anaInmAmps(unsigned int channel);
Reads the state of an analog input channel and uses the previously set calibration con-
stants to convert it to current.
channel
A current value between 4.00 and 20.00 mA corresponding to the current on the analog
input channel.
ADSPIBUSY (-4094) if the A/D converter is locked out or if the SPI port is in use (if
more than _SPI_MAXTIME milliseconds elapse since the last attempt to grab the port
semaphore by the A/D converter, a fatal runtime error, -ETIME, results).
ADTIMEOUT (-4095) if the conversion is incomplete or busy bit timeout.
ADOVERFLOW (-4096) for overflow or out of range.
anaInCalib, anaIn, anaInVolts
the channel number (0 to 7) corresponding to LN0 to LN7.
