PARAMETERS
RabbitCore RCM3700 User’s Manual
unsigned int anaIn(unsigned int channel,
Reads the value of an analog input channel using the direct method of addressing the ADS7870 A/D
converter. The A/D converter is enabled the first time this function is called—this will take approxi-
mately 1 second to ensure that the A/D converter capacitor is fully charged.
channel is the channel number (0 to 7) corresponding to ADC_IN0 to ADC_IN7
opmode is the mode of operation:
gaincode is the gain code of 0 to 7
int opmode, int gaincode);
SINGLE—single-ended input
DIFF—differential input
mAMP—4–20 mA input
