May I have a reference code on how to communicate with CN0234 gas detector using Arduino.
The internet have little resources regarding on this board, the closest we can get is CN0396 which have slight difference compare with CN0234.
Link to website above: https://github.com/analogdevicesinc/arduino/tree/master/Arduino%20Uno%20R3/examples/CN0396_example
Looking forward the support.
So there is no reference code available for the CN0234, this software was done with LabVIEW.
We do have another design which is very close to the CN0234, called the CN0357. Here is the URL for that board. (https://www.analog.com/en/design-center/evaluation-hardware-and-software/evaluation-boards-kits/EVAL-CN0357-ARDZ.html) There is reference code written for this board using an Arduino Uno Rev 3, which can be found here, just look for the CN0357. (https://github.com/analogdevicesinc/arduino/tree/master/Arduino%20Uno%20R3)
Hope this helps.
