Teensy Keyer - Midi command requirements?

[radi...@mail.com]

Searched on the GitHub in the project notes but I don't see anywhere a basic description of what midi commands would need to be implemented by the receiving software in order to use the keyer?

At the most basic level, what commands need to be implemented simply to key the SDR software in CW mode? Presumably the SDR software needs to receive one midi command to signal key-down? Maybe another to activate PTT prior? Or more complex than that?

As a potential user (not a programmer) I'm just trying to get a handle on how to implement the most basic operation? Maybe it has already been covered in discussions here but there are already many threads about the keyer. The description on GitHub just says "Ctrlr TBD: Basic description, download and use instructions for Ctrlr MIDI control panel."

I don't see any other reference to midi commands. Sorry if it's obvious and I've missed it somewhere?

I built mine on just a T4.0+SGTL5000 and back then each keyer app tested back then (TeensyWinKeyEmultor, Hasak, Prototype, K3NG) each of the keyer versions had slightly different code usages.

Some discussion about this is here:  CWKeyerShield Library · softerhardware/CWKeyer · Discussion #19 (github.com) 

Most of the SDR apps have a MIDI configure and test page.  IF you have a keyer running, you can operate each knob, switch and keyer input and see what code(s) is produced and assign them as you see fit.

This file and other similar header files lists their MIDI note assignments:  CWKeyer/software/cwkeyer/cwkeyer.py at main · softerhardware/CWKeyer (github.com)

There is only one "trick" you have to know when configuring your SDR program:

sometimes the keyers are set up as to send a "PTT ON" command when you start,
and a "PTT OFF" command after a hang time. If the SDR program MIDI assignment
refers to the *latest* MIDI command that arrived, then to assign the
Key down/up signal you have to press+hold the key, such that a sequence of
dashes and dots arrives. When you are finished with this, release the key
such that eventually a PTT command arrives then you can assign that one.

If you are unlucky and the SDR program assigns the *first* MIDI event seen,
you have to deactivate the PTT output in the keyer software before you
can assign the key up/down signal.

Hello,

I use radioberry hardware with RPI4. I build a very simple midi controler in Cpython

https://framagit.org/remis732/pico2040midicontroller

No compilation for adjustement : just chnage online code.py file

As explained in radioberry groups I'm not able to change RX-gain with any midi value. It works for VFO , AF gain... with WHEEL mode

Does somebody know which range value to send to see Rx-gain changes ?
