# Project: USB Morse Adapter
|
||||
# Vail Adapter: Morse Code Key/Paddle to USB
|
||||
|
||||
![Vail adapter, assembled and connected](https://lh3.googleusercontent.com/pw/ACtC-3d9xbLxL23QeLm-3gy3-Yt0VHE3IlQ-qyMDqTfdF6Bo7fHkkokACdIs68pmXevu14VzrrCeKj1JmRUiekUNiZe9J9rYIh_pTagvCbKSzpY8Ynp1m6cF4G_jTvtiU5eRtoNCsmU5OLy2SR9kYcCDYSt-AA=s1471-no)
|
||||
|
||||
This translates Morse key inputs into USB events,
|
||||
either MIDI or MIDI+Keyboard,
|
||||
so you can use a computer.
|
||||
|
||||
It is fully compatible with [VBand](https://hamradio.solutions/vband/)
|
||||
and anything else that uses the VBand adapter.
|
||||
|
||||
I use this with an Internet morse code repeater I wrote,
|
||||
available at https://vail.woozle.org/.
|
||||
|
||||
This project requires an Arduino that can send USB.
|
||||
The following should work:
|
||||
|
||||
### Verified Working
|
||||
|
||||
* Seeeduino Xiao **(recommended)**
|
||||
* Arduino Micro
|
||||
* KeeYees Pro Micro
|
||||
|
||||
### Unverified but should work
|
||||
|
||||
Any USB-capable Arduino should be fine, including:
|
||||
|
||||
* Arduino Leonardo
|
||||
* Arduino Zero
|
||||
* Adafruit Trinket M0
|
||||
* Adafruit GEMMA M0
|
||||
* Adafruit Feather M0
|
||||
|
||||
It may also be possible to get this working on a DigiSpark.
|
||||
I'm trying to convince Michele Giugliano to try :)
|
||||
|
||||
=== Similar projects
|
||||
|
||||
* Vail user Michele Giugliano's [MorsePaddle2USB](https://github.com/mgiugliano/MorsePaddle2USB),
|
||||
which runs on a DigiSpark (attiny85). It only sends keystrokes, so you must keep the Vail
|
||||
window focused: you can't switch to other apps and still transimit.
|
||||
* Ham Radio Solutions sells a [USB Paddle Interface](https://hamradio.solutions/vband/)
|
||||
which appears to be very similar to Michele's project. You must keep the Vail window focused.
|
||||
|
||||
## Step 1: Installation
|
||||
|
||||
#### The Easy Way
|
||||
|
||||
1. Get a Seeeduino XIAO
|
||||
2. Download the most recent xiao firmware from
|
||||
[releases](https://github.com/nealey/vail-adapter/releases)
|
||||
3. [Enter bootloader mode](https://wiki.seeedstudio.com/Seeeduino-XIAO/#enter-bootloader-mode)
|
||||
4. Copy the firmware onto the XIAO
|
||||
|
||||
A longer write-up is [on the wiki](https://github.com/nealey/vail-adapter/wiki/Flashing-firmware).
|
||||
|
||||
#### The Other Way
|
||||
|
||||
Install the MidiUSB and Keyboard libraries.
|
||||
These are highly popular libraries,
|
||||
and there is much better documentation elsewhere on the Internet.
|
||||
The code should then build in the Arduino IDE.
|
||||
|
||||
## Step 2: Assmble the circuit
|
||||
|
||||
### For the impatient:
|
||||
|
||||
[Photos of assembled circuit](https://github.com/nealey/vail-adapter/wiki)
|
||||
|
||||
### For the inquisitive:
|
||||
|
||||
Morse code keyers are very simple devices,
|
||||
they just connect two wires together.
|
||||
You could use a button if you wanted to,
|
||||
or even touch wires together.
|
||||
|
||||
The only real complication here is that some browsers
|
||||
need to get keyboard events instead of musical instrument events.
|
||||
|
||||
The Vail adapter boots into a mode that sends both keyboard events
|
||||
and MIDI messages.
|
||||
If it receives a MIDI key release event
|
||||
on channel 0
|
||||
for note C0,
|
||||
it will disable keyboard events.
|
||||
|
||||
Vail sends this "disable keyboard" MIDI event, so as soon as you
|
||||
load up Vail, the keyboard events are disabled, and your adapter
|
||||
will no longer interfere with your typing.
|
||||
If your browser doesn't support MIDI,
|
||||
the disable command can't be sent,
|
||||
and it keeps on sending keystrokes.
|
||||
|
||||
### Wire up your input device
|
||||
|
||||
Hook a straight key into ground on one side,
|
||||
pin 10 on the other.
|
||||
It's okay to leave pin 10 disconnected if you don't have a straight key.
|
||||
|
||||
Hook an iambic paddle in ground in the middle,
|
||||
pins 11 and 12 on the outside posts.
|
||||
It's okay to leave pins 11 and 12 disconnected if you don't have a paddle.
|
||||
|
||||
=== Using a headphone jack
|
||||
|
||||
If you prefer, you can wire a headphone jack up to GND, 11, and 12.
|
||||
GND should be the sleeve, 11 the ring, and 12 the tip.
|
||||
|
||||
o --- 12
|
||||
|_| --- 11
|
||||
| | --- GND
|
||||
| |
|
||||
|
||||
Make sure any straight key you plug in has a TS adapter (mono plug):
|
||||
this will short pin 11 to ground and signal to the Arduino to
|
||||
go into straight key mode.
|
||||
|
||||
If you change from an iambic key to a straight key,
|
||||
you'll have to reset the adapter by unplugging it from the computer.
|
||||

|
||||
|
||||
|
||||
## Step 3: Load the code
|
||||
# Features
|
||||
|
||||
Upload the code contained in this sketch on to your board.
|
||||
* Lets you key even if you move focus to another window
|
||||
* Works with [Vail](https://vail.woozle.org/)
|
||||
* Works with [VBand](https://hamradio.solutions/vband/), but the window has to remain focused
|
||||
* Optional sidetone generator, which helps with latency
|
||||
* Implements all nine keyer modes from Vail, in the adapter, so you lunatics can try to key at 50WPM with no latency issues
|
||||
* Plays received signals in the adapter, so you can turn off your computer speaker
|
||||
* Free firmware updates for life
|
||||
* Can be wired up in about 5 minutes
|
||||
|
||||
## Step 4: Test it out
|
||||
[Vail Adapter benefits video](https://www.youtube.com/watch?v=XQ-mwdyLkOY) (4:46)
|
||||
|
||||
Make sure it's plugged in to your computer's USB port.
|
||||
# Setting Up
|
||||
|
||||
If you connected pin 9 to ground,
|
||||
Open anything where you can type,
|
||||
type in "hello", and hit the straight key.
|
||||
You should see a comma after your hello.
|
||||
|
||||
Now you can open https://vail.woozle.org/,
|
||||
click the "KEY" button once to let the browser know it's okay to make sound,
|
||||
and you should be able to wail away on your new USB keyer.
|
||||
|
||||
## Step 5: Debugging
|
||||
|
||||
If you plug in your straight key and it looks like DAH is being held down,
|
||||
it means you need to switch the connections to pins 11 and 12.
|
||||
|
||||
If you plug in your straight key and it looks like DIT is being held down,
|
||||
it means you need to reset the Arduino to make it detect the key type again.

# Vail MIDI Protocol
|
||||
|
||||
When it boots,
|
||||
the Vail adapter sends left and right Control keyboard key up and down events.
|
||||
It also shows up as a MIDI device.
|
||||
|
||||
The Vail web site sends MIDI control commands to enable MIDI keyer mode,
|
||||
tells the keyer what sideband pitch to generate,
|
||||
and can set the keyer mode.
|
||||
|
||||
|
||||
## Controller 0 - MIDI Mode
|
||||
|
||||
`b0 00 ff` will enable MIDI mode and disable Keyboard mode
|
||||
|
||||
`b0 00 00` will enable Keyboard mode and disable MIDI mode
|
||||
|
||||
|
||||
## Controller 1 - dit length
|
||||
|
||||
`b0 00 xx` will set the dit duration to `xx` times 2 milliseconds
|
||||
|
||||
|
||||
## Controller 2 - sidetone note
|
||||
|
||||
`b0 00 xx` will play note `xx` as the sidetone note
|
||||
|
||||
|
||||
## Program Change
|
||||
|
||||
`c0 xx` will change the keyer mode to `xx`.
|
||||
|
||||
|
||||
### Keyer Modes
|
||||
|
||||
* 0: passthrough (sends C# and D for dit and dah)
|
||||
* 1: cootie / straight key
|
||||
* 2: bug
|
||||
* 3: electric bug
|
||||
* 4: single dot
|
||||
* 5: ultimatic
|
||||
* 6: plain iambic
|
||||
* 7: iambic a
|
||||
* 8: iambic b
|
||||
* 9: keyahead
|
||||
|
||||
Any other mode will set to passthrough.
|
||||
|
||||
|
||||
## Notes (key down / key up)
|
||||
|
||||
`90 00 xx` will begin playing note `xx`
|
||||
`80 00 xx` will end playing note `xx`
|
||||
|
||||
These work just like a regular MIDI synthesizer.

# Advanced Install
|
||||
|
||||
In the Arduino IDE, edit [vail-adapter.ino](../vail-adapter.ino) with the pins
|
||||
you want to use on your device.
|
||||
|
||||
You will need the MidiUSB and Keyboard libraries installed.
|
||||
You can do this through the Library manager.
|
||||
|
||||
Then compile and upload the sketch.
|
||||
|
||||
|
||||
## Works with no source code changes
|
||||
|
||||
* Seeeduino Xiao SAMD21
|
||||
* Adafruit Qt Py SAMD21
|
||||
|
||||
## Known to work with source code changes
|
||||
|
||||
* Arduino Micro
|
||||
* KeeYees Pro Micro
|
||||
* Arduino Leonardo
|
||||
* Arduino Zero
|
||||
* Adafruit Trinket M0
|
||||
* Adafruit GEMMA M0
|
||||
* Adafruit Feather M0
|
||||
|
||||
## Will Not Work!
|
||||
|
||||
The RP2040 chip will not work, because it lacks a USB MCU,
|
||||
needed by the MIDIUSB library.
|
||||
I'm listing specific devices here
|
||||
in the hopes that seeing them crossed out will prevent people from
|
||||
making a purchasing mistake!
|
||||
|
||||
* ~~Seeeduino Xiao RP2040~~ Will not work!
|
||||
* ~~Adafruit Qt Pi RP2040~~ Will not work!
|
||||
* ~~Any RP2040 Device~~ Will not work!

# Advanced Wiring
|
||||
|
||||
![XIAO Pinout](https://files.seeedstudio.com/wiki/Seeeduino-XIAO/img/Seeeduino-XIAO-pinout-1.jpg)
|
||||
|
||||
* GND: Ground
|
||||
* D2: Dit
|
||||
* D1: Dah
|
||||
* D0: Straight Key
|
||||
* D10: Speaker or Passive piezo buzzer
|
||||
* A6: Capacative Dit
|
||||
* A7: Capacative Dah
|
||||
* A8: Capacative Straight Key
|
||||
|
||||
|
||||
## Using a headphone jack
|
||||
|
||||
You can wire a headphone jack up to GND, D1, and D2.
|
||||
GND should be the sleeve, D1 the ring, and D2 the tip.
|
||||
|
||||
o --- D2 (tip, dit)
|
||||
|_| --- D1 (ring, dah)
|
||||
| | --- GND (sleeve)
|
||||
| |
|
||||
|
||||
## Sidetone generator
|
||||
|
||||
If you connect a buzzer or speaker to pin 10 on one leg,
|
||||
and ground on the other,
|
||||
the adapter will beep when you press the straight key.
|
||||
|
||||
This will help a lot if there is a noticeable delay between when you press the key
|
||||
and when your computer starts making a local beeping sound.
|
||||
|
||||
If you feel like no matter what you do,
|
||||
you're always getting DAH with your straight key,
|
||||
you should try this.
|
||||
|
||||
|
||||
## Capacative Touch
|
||||
|
||||
The adapter works as a capacative touch sensor,
|
||||
like a touch lamp.
|
||||
|
||||
You might wire these pins to screws or conductive pads.
|
||||
These can be used instead of, or in additon to, the normal pins D0, D1, and D2.
|
||||
|
||||
You do not need a ground wire with capacative touch!
|
||||
|
||||
* Pin A6: Dit capacative touch
|
||||
* Pin A7: Dah capacative touch
|
||||
* Pin A8: Straight key capacative touch
