Re: New MCP690X Thermocouple Component.
Hi Martin Hi Jorgen
I use the sparkfun MCP9600 screw terminal board and an ESP32.
If I use I2C Softwaremode I can read the temp from the sensor correct.
but the K element gives me also some value but in the wrong direction
when I increase the temperature, the MCP9600 measures less.
In ic2 channel1 mode, it's not working. Always get 1931 as value.
I am still doing something wrong?

Hi Stefan Erni!
Sorry I have not mine connected up at the moment. I will try if I get time during the weekend. Could you please att. your project then I could give it a try.

Re: New MCP690X Thermocouple Component.
Hi Jorgen
I was able to solve one problem.
Until now, I always thought of the colour red as positive voltage and the colour yellow as ground, but not with the K-elements
The incorrect values are due to the different colours of the sensors wire. Red is not always the positive pin and yellow the negative.
So I have turned the sensor wires and the temperature is now measured in the correct direction. An info about Thermocouple; a short description of my project:
My Board with a ESP32 and sd-card 4wire: a few sensors
I have not yet decided whether I will use it for screwing or plugging
screw: plug: i have not decided yet if i will change the board with the addresses or use a multiplexer I can give you parts of my software if you are interested
regards
Stefan

Re: New MCP690X Thermocouple Component.
Hi Martin
in the future i will create a simpler programme only with sensor i hope it will work for me too.
I think I'm on the right track to build a very good temperature logger with flowcode.
I have to build a logger which during 2 minutes
the temperature at 8 positions and record it.
During this time I measure with 10hz and expect a temperature of 20 degrees up to 50 degrees. I want to measure with a resolution of 0.1 degree
it's working at the moment. But there is still a small problem.
I do a simple test and touch the sensor
When I read out the 16 bit integer I get a resolution of 1 degree celsius. This is not useful.
If I read float I get much more accurate values. I use 10Hz samplerate
but even with float there are large jumps and the values remain the same during some measurements.
This MPC9600 has many settings. How can I adjust these or know what they are set to?
Samplerate and resolution: read 16bit: read Float:
