float anaInVolts(unsigned int channel);
Reads the state of an A/D converter input channel and uses the previously set calibration constants to
convert it to volts.
PARAMETER
channel is the A/D converter input channel (0–10).
RETURN VALUE
A voltage value corresponding to the voltage on the analog input channel.
SEE ALSO
anaIn, anaInCalib, brdInit
int anaInEERd(unsigned int channel);
Reads the calibration constants, gain, and offset from the simulated EEPROM in flash memory (located
in reserved user block memory area 0x1C00–0x1FFF).
PARAMETER
channel is the A/D converter input channel (0–10).
RETURN VALUE
0 if successful.
-1 if address or range is invalid.

anaInEEWr, brdInit
int anaInEEWr(unsigned int channel);
Writes the calibration constants, gain, and offset to the simulated EEPROM in flash memory (located in
reserved user block memory area 0x1C00–0x1FFF).
PARAMETER
channel is the A/D converter input channel (0–10).
RETURN VALUE
0 if successful.
-1 if address or range is invalid.
