Hello all
If this is of any interest to anyone, would be very glad of help.
Sitation presented here - page on own website.

"Try 1st - Arduino + MCP9600 + thermocouple"
So that's
Arduino + MCP9600 thermocouple amplifier + thermocouple
The "breakout board" can be seen here

So yes, for sure, guidance would be appreciated.
Best wishes,

Each I2C string begins with the address of the target, which you have to know to communicate with it. Around 2000 I wrote a program that controlled a Texas Instruments Power Over Ethernet applications board using the printer port of a computer to generate the I2C address and SDA + SCL signals, so the board and cable could plug into a customer's unmodified lab PC. A 2 channel digital storage scope with a decent amount of waveform memory should let you capture, view and analyze the command sequences. Don't ALTernate the SCL and SDA channels, their phasing is critical. You can experiment with how triggering and sweep mode work by turning a power supply on and off.
My thermocouple amplifiers have analog outputs that a PC-connected DVM can read, some can read Type K directly. I haven't played with I2C since then and don't remember the details. I understand structured programming but I'm not all that familiar with the subtleties of C.
Like the lathe and mill, you won't get far in electronics without an oscilloscope. My small portable one is a used Tenma that I took a chance on at a flea market. It's somewhat noisy but good enough for hobby use. At least one metered current-limited power supply is very useful, partly for its fault detection and protection ability. I prefer 4-1/2 digit precision on one multimeter for working on measurement circuits, otherwise 3-1/2 should be fine.
