A Simple I2C Thermocouple Measurement Solution

Post by Jon Chandler » Sat Jan 22, 2011 11:30 pm

I have published an article at Digital-DIY with an I2C circuit and modules for reading a thermocouple. The circuit uses a TI TMP513 Power Supply Monitor to read the thermocouple and reference junction temperature.

Two Swordfish modules are provided. The first is a Type-K thermocouple table, and the second is the module to control the TMP513 and make the temperature calculations. Using the module involves a single function call to read the temperature in degrees C.

The picture below shows the thermocouple circuit, which is built on an SOIC adapter board, connected to a TAP-28 PIC Application board.
