Group,
? I recently upgraded to a V5 board and a Nextion. 2.4" display.? I want to make the signal and the spectrum screen work but I am confused on how to exactly to do this. I looked on this page?
But there are 2 ways to do this and it is not clear what the difference is between them and there is no reference to what software to put on the second Arduino do I load the same software as the the Raduino?
Thanks
