kill my Teensy 3.2. I unplugged the Teensy-to-Raduino comm lines in
order to program the Raduino. When I plugged them back in, I didn't
realize that I was off by one pin. So I believe something that
should've only gotten 3.3V, got more. No light on the Teensy.
This development effort, while it has been fruitful, is definitely
complicated. I don't think I have the bandwidth to continue it. I plan
on merging all the branches back to master, collecting the pieces-parts
of uBITX V5D, and calling it "done". I will rebuild my uBITX V5 back
into a relatively stock configuration, and use an external digital
interface (see KK5JY).
Support for full 16-char status line to be sent to the Raduino.
Added rotary encoder support.
Everything above has been tested and works.
Added rudimentary top-level menu. Compiles, but not tested yet.
Biggest thing, discovered that I needed to increase AudioMemory to 16 to
fix some "motorboating" that seemed to startup anytime I transmitted
through USB.
Raduino. It was intended to be more extensive, but I had to roll some
of it back. Mostly just sharing of enums/types currently.
Currently in "factory calibration" mode. Comms (CAT) in normal mode
needs to be re-checked.
Added two tone test mode, with two new modes available via Raduino menu:
TTL and TTU.
Using test mode, I'm thinking that the proper TX output calibration,
assuming a full-scale 700/1900 test tone, is either:
0.061 (which I believe gives a 25 mV RMS output), or
~0.100 (which is just before the audio starts to distort, in terms of
visible harmonics in the spectrum at the 45 MHz IF.
