Chapter

Application Programming Examples

This chapter provides two application examples to help you use the

module.

• Basic example

• Supplementary example

The basic example lets you display a temperature.

The supplementary example lets you manually select the display of

temperature in °C or °F.

Basic Example

(to display a temperature)

This example lets you display the temperature of a bath °F on an LED

indicator display device. The display device requires BCD data, so the

program must convert the temperature reading to BCD.

Channel Configuration

Configure the thermocouple channel with the following setup:

• Type J thermocouple (bits 3…0)

• °F displayed in whole degrees with EU = x10 (bits 8, 5, 4)

• Set the data word to zero in the event of an open-circuit

(bits 7, 6)
