Thanks for getting back to me. Since my software expertise is limited and I don’t understand how all the code in ModularSensors works I have not been able to get “calculated variable” to compile in my simple_logging.ino code. I have been successful in getting the code to work with external_voltage and the Atlas EZO circuits (EC and pH). I attached a screenshot of what works with the calculated variable code commented out. I suspect my problem has something to do with pointers.
Your help would be appreciated. I probably need step by step instructions of if there simple fix to my code that would be great!
