Charles_Gibbs:
The code I put in to do the switch with, made the the Arduino read ONLY the bmv's data in the serial monitor when the switched state was low, when I switched it high the mppt's data was not read in the serial monitor, the data stopped the rx/tx leds stopped responding as well.When I made the switched state low again it would see the data again from the bmv, the only thing I changed was the switch state NOTHING else.
I did not reset the Arduino or stop the serial monitor. So, from low to high, stopped the serial monitor from reading any data until it was put back to the low state and the rx/tx leds also stopped when the state was high.
First, am I correct to think that all of the text I have quoted is referring to displaying the data on the Serial Monitor and has NOTHING to do with the Victron program?
If I am correct please post the program that these paragraphs refer to.
