54 eDisplay (OP7200)

• MASTER.C—This program demonstrates a simple RS-485 transmission of lower case

letters to a slave. The slave will send back converted upper case letters back to the

master OP7200 and display them in the STDIO window. Use SLAVE.C to program the

slave.

• SLAVE.C—This program demonstrates a simple RS-485 transmission of lower case

letters to a master OP7200. The slave will send back converted upper case letters back

to the master OP7200 and display them in the STDIO window. Use MASTER.C to pro-

gram the master OP7200.

4.3.4 A/D Converter Inputs

The following sample programs are found in the ADC subdirectory in SAMPLES\OP7200.

• ADCAL_DIFF_2V.C—Demonstrates how to recalibrate an A/D input channel being

used for a differential input with the input attenuator tied to the 2 V reference voltage.

• ADCAL_DIFF_GND.C—Demonstrates how to recalibrate an A/D input channel being

used for a differential input with the input attenuator tied to analog ground.

• ADCAL_MA_CH.C—Demonstrates how to recalibrate an A/D input channel being used to

convert analog current measurements to generate the calibration constants for that channel.

• ADCAL_SE_ALL.C—Demonstrates how to recalibrate all single-ended A/D input chan-

nels for a given gain.

• ADCAL_SE_CH.C—Demonstrates how to recalibrate one single-ended A/D input chan-

nels to generate the calibration constants for that channel.

NOTE: The above sample programs will overwrite the calibration constants set at the factory.

• ADRD_DIFF_2V.C—Demonstrates how to read an A/D input channel being used for a

differential input with the input attenuator tied to the 2 V reference voltage.

• ADRD_DIFF_GND.C—Demonstrates how to read an A/D input channel being used for

a differential input with the input attenuator tied to analog ground.

• ADRD_MA_CH.C—Demonstrates how to read an A/D input channel being used to con-

vert analog current measurements using previously defined calibration constants for

that channel.

• ADRD_SE_ALL.C—Demonstrates how to read all single-ended A/D input channels

using previously defined calibration constants.

• ADRD_SE_CH.C—Demonstrates how to read one single-ended A/D input channels

using previously defined calibration constants.
