Hi to all
In a working program i can not change the calculation anymore. It's empty.
Before i have rename the variable from themp_16 to temp_16.
Maybe a problem?

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 t...

Re: ESP32 and i2c multiplexer TCA9548A
Hi Martin
The other component also works well, but only in software mode I2c bus.
Do you have any idea why the three components only work in software mode?

Re: ESP32 and i2c multiplexer TCA9548A
Hi Martin Now I have understood. With the multiplexer TCA9548A I can select 1 of the 8 “qwii i2c connectors”. But I can also use 8 different multiplexers TCA9548A with these A2, A1, A0. Address selector. With the other component I simply select the address in hex if I use several TCA9548A. I will te...

ESP32 and i2c multiplexer TCA9548A
Hi to all I use the i2c multiplexer and it works great. Very convenient to connect 8 different temperature sensors boards. with Flowcode just one loop and read all sensors in an array. But this i2c multiplexer module only works in i2c software mode. Then I have a question about the address bit prope...

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 negat...

Re: ESP32 and LSM9DS1 not compiling
Hi Ben There is still a small problem on the component with the temperature reading. The temperature is displayed from -20000 to -5000 but I suspect this has something to do with the the output of the sensor is 0 (typ) at 25 degrees Celsius. Do you have any idea how this works? maybe I can simply co...

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 m...

Re: ESP32 and LSM9DS1 not compiling
Hi Ben Perfect! it's working nice! The data is from the Accelerometer und Gyro is now ok, and the program can now dedect, if one or both sensor are connected and save one or both sensor data in a CSV File. I will still try to read and write the registers but that will take a little more time. I have...
