Further details on Nextion Display and second arduino

Ian KD8CEC, in his third article on using a second arduino with the µBITx, demonstrates the signal scope feature made possible with having a dedicated ardunio nano connected to the main Raduino control processor via i2c lines.

The signal scope shows a section of the band surrounding the currently tuned frequency IN REAL TIME.    The nano and the serial connections to the Nextion doesn’t have the agility to provide a full blown waterfall display, but a real time display of signals around where you are currently tuned is still pretty impressive.

The other feature that is present in the Nextion display version of this arduino add-on, is a CW decode function.

Bring on the release of v1.097 of CEC firmware!
