Hi Jorgen,
I have fixed the issue with upper temperature limit.
I have also discovered the ReadThermocouple_Int & ReadReference_Int was not displaying temperatures below 0C correctly
To try the fixed version:
In file explorer address bar, paste this:
Code: Select all
C:\ProgramData\MatrixTSL\FlowcodeV9\Components
Extract the component within the attached zip file and save it into the above hidden folder.
Just select ok to replace the current file.
If you got Flowcode loaded when file was placed in the components directory, you must select the reload icon before compiling again.

I will let you know when the component has been pushed on to the update system.
Then the above steps will not be required.

Hi Martin!
Yes, perfect Martin, now I have seen up to 900 degree and with my freeze spray at least down to -55 degre
Now I can make some control for my stove and other equipment with very high temperatures.
And when I compare the temperature (low temp) with a DS18b20, the are equal. And amazing I can heat this little tip up until it is red and then cool slowly down again and then it go back to same temp from where I started.
Thank you Martin, one more component for FC9, push it to update, aproved.....

That's great!.
Yes the range is far superior when compared with other temperature sensors like DS18b20, LM335 and thermistors etc.
It Looks like there has been an update of the MCP960X now.
Thanks, Ben.

Thank´s to both. I have made some more test and measuring with the K element, working perfect. By the way Martin, very nice examble you have made
For a while ago I try the component MAX31855 in FC9 and it doesn´t work so i am glad for the new.
Have a nice day....
Jorgen.

Hi Martin!
Merry Christmas!
Do you think your MCP690X component will run on ESP32 and an Ili9341 display?

Hi Jorgen.
Thanks, Merry Christmas to you.
When the component was created, it used I2C transaction code.
That means it should work with ESP32.
MCP690x is independent to Ili9341.
Therefore if Ili9341 works on ESP32 already, then it should work with MCP690x

I made a testprogrgam. It work in simulation and no problem to compile to hex. I test in real world tomorrow and you hear. You are welcome to correct if there is room for improvement
