ADC_CAL_DIFF.C
channel using two measured voltages to generate two coefficients, gain and offset,
which are rewritten into the user block. The voltage that is being monitored is displayed
continuously.
Once you compile and run this sample program, connect the power supply across a
differential channel pair, then follow the instructions in the Dynamic C
ADC_CAL_MA.C
using two measured currents to generate two coefficients, gain and offset, which are
rewritten into the reserved user block. The current that is being monitored is displayed
continuously.
Before you compile and run this sample program, jumper pins 1–2 and 5–6 on headers
J10 and J11. Then connect a current meter in series with the power supply connected to
one of pins AIN0–AIN3 and AGND, then compile and run the sample program, and
follow the instructions in the Dynamic C
ADC_CAL_SE_UNIPOLAR.C
A/D converter channel using two measured voltages to generate two coefficients, gain
and offset, which are rewritten into the reserved user block. The voltage that is being
monitored is displayed continuously.
Before you compile and run this sample program, connect the power supply (which
should be OFF) between the pin (AIN0–AIN7) of the channel you are calibrating and
AGND, then compile and run the sample program, and follow the instructions in the
Dynamic C
ADC_AVERAGING_SE_UNIPOLAR.C
age voltage of each of the single-ended analog input channels using a sliding window.
The voltage is calculated from coefficients read from the display—the two calibration
coefficients, gain and offset, in the Dynamic C
mode of operation.
Before you compile and run this sample program, connect the power supply (which
should be OFF) between the pin (AIN0–AIN7) of an analog input channel and AGND,
then compile and run the sample program, and follow the instructions in the Dynamic C
