Update: I have stopped working on this version, and recommend m8c. It's definitely more mature, and has more cool stuff implemented. They now have support for similar (hacky) audio-routing in SDL, which was the original purpose of this, for me (easier config of auto-routing.)
Remote display for the Dirtywave M8
I first tried M8WebDisplay then discovered m8c and decided to use it as a starting point for my own version in rust..
You can get device-specific tips in DEVICES.
Alt + Enter will toggle fullscreen.
Alt + R key will reset the display
Alt + Shift + R key will do a full reset of the display (disconnect + enable and reset display)
Alt + C will enter config mode. THink of this as "extreme dev secret everything-broke menu". Many options will crash rm8.
Escape will either quit the application or fullscreen mode or config mode or key remapping mode.
UP = UP # M8's `UP` key
DOWN = DOWN # M8's `DOWN` key
LEFT = LEFT # M8's `LEFT` key
RIGHT = RIGHT # M8's `RIGHT` key
SHIFT = LSHIFT # M8's `SHIFT` key
PLAY = SPACE # M8's `PLAY` key
EDIT = Z # M8's `EDIT` key
OPTION = X # M8's `OPTION` key
KEYJAZZ = RETURN # Enter keyjazz mode
OCTAVE+ = RIGHTBRACKET # Increment octave
OCTAVE- = LEFTBRACKET # Decrement octave
VELOCITY+ = MINUS # Increment velocity (use the keyboard's `Shift` key to go faster)
VELOCITY- = EQUALS # Decrement velocity (use the keyboard's `Shift` key to go faster)The following keys are used in keyjazz mode to send notes to the M8:
If you are using an azerty or dvorak keyboard layout, you may want to change the keys.
For that, open or generate the config file and look for the "keyjazz" section.
The numbers on the right are the index of the note.
NOTE: If the keys do not overlap with keyjazz keys, then keyjazz can be left ON.
Run rm8 -help to display the help screen.
Run rm8 -list to list available M8 devices.
Run rm8 -dev DEVICE to connect to the specified M8 device.
Run rm8 -cap "M8 Analog Stereo (2)" to connect the given capture device to the default playback device.
Run rm8 -wc to print the default config to the standard output.
Run rm8 -wc <FILE> to write the config to the given file.
Run rm8 -rc <FILE> to load the config from FILE.
NOTE: The default config file name is rm8.json.
rm8 can now directly output the audio from your M8 !
You can either run rm8 and let it open the first M8 capture device it found or you can use the -cap command line argument to specify which M8 you want to use.
For now there is no support for this feature in the in-app config system.
By pressing Alt + C you will enter config mode.
In this mode, you can redefine most params of the application.
The parameters are split in 8 pages.
Pressing Edit and Option on a control will reset it to its default value.
Navigate using Shift and ARROWs just like on the M8.
Press Escape at any time to exit config mode. (Press twice if your were in remapping mode).
On this page you will be able to configure:
Alt + Enter to toggle fullscreen).Press RESET to restore the application settings to their last saved state.
Press SAVE to save the application settings to the config file.
On this page you will be able to configure the colors of the application:
Press RESET to restore the theme settings to their last saved state.
Press SAVE to save the theme settings to the config file.
On this page you will be able to map the keys to control your M8:
Press REMAP button to enter remap mode and redefine the keys.
Press Escape to exit remapping mode.
Press RESET to restore the M8 key settings to their last saved state.
Press SAVE to save the M8 key settings to the config file.
On this page you will be able to map the keys to control the application:
Press REMAP button to enter remap mode and redefine the keys.
Press Escape to exit remapping mode.
Press RESET to restore the RM8 key settings to their last saved state.
Press SAVE to save the RM8 key settings to the config file.
On the main config page you will be able to select your joystick.
If no joysticks are connected, you will only see this information:
If you have at least one joystick connected, you will see this information:
Press RESET to restore ALL the settings of your joystick to their last saved state.
Press SAVE to save the ALL the settings of your joystic to the config file.
On this page you will be able to configure the axes of your joystick.
Currently, only 6 axes are supported.
For each axis, you will be able to associate 2 commands (for negative and positive).
You will also be able to configure the axis sensibility in order to avoid spurious triggers.
Press RESET to restore the Axes settings to their last saved state.
Press SAVE to save the Axes settings to the config file.
On this page you will be able to configure the buttons of your joystick.
Currently, only 20 buttons are supported. For each button, you will be able to associate 1 command.
Press RESET to restore the Buttons settings to their last saved state.
Press SAVE to save the Buttons settings to the config file.
On this page you will be able to configure the hats of your joystick.
Currently, only one hat is supported.
For each state of the hat, you will be able to associate 1 command.
The states are:
Press RESET to restore the Hat settings to their last saved state.
Press SAVE to save the Hat settings to the config file.
The code for handling joysticks may be a bit buggy as I do not have enough experience in dealing with these devices.
This project uses rust
You need to install rust and then issue: cargo build --release in the project's directory.
The program can then be found in the directory target/release.
You can strip symbols from this binary using strip rm8.
You can also compress the binary to gain some extra bytes using upx --best --lzma rm8.
This project uses:
This project uses a bitmap render of the font stealth57.ttf by Trash80.
Original font available at https://fontstruct.com/fontstructions/show/413734/stealth57
Originally licensed under a Creative Commons Attribution Share Alike license, https://creativecommons.org/licenses/by-sa/3.0/
I modified the bitmap rendered font to support both alternate zeros from the newer firmwares.
However, as I do not yet have a real M8, I don't know if there are differences with the font on newer firmwares.
M8 SLIP Serial Receive command list
'S' - Theme Color command: 4 bytes. First byte is index (0 to 12), following 3 bytes is R, G, and B
'C' - Joypad/Controller command: 1 byte. Represents all 8 keys in hardware pin order: LEFT|UP|DOWN|SELECT|START|RIGHT|OPT|EDIT
'K' - Keyjazz note command: 1 or 2 bytes.
First byte is note, second is velocity, if note is zero stops note and does not expect a second byte.
'D' - Disable command. Send this command when disconnecting from M8. No extra bytes following
'E' - Enable display command: No extra bytes following
'R' - Reset display command: No extra bytes following
M8 SLIP Serial Send command list
251 - Joypad key pressed state (hardware M8 only) - sends the keypress state as a single byte in hardware pin order:
LEFT|UP|DOWN|SELECT|START|RIGHT|OPT|EDIT
252 - Draw oscilloscope waveform command:
zero bytes if off - uint8 r, uint8 g, uint8 b, followed by 320 byte value array containing the waveform
253 - Draw character command: 12 bytes. char c, int16 x position, int16 y position,
uint8 r, uint8 g, uint8 b, uint8 r_background, uint8 g_background, uint8 b_background
254 - Draw rectangle command: 12 bytes. int16 x position, int16 y position,
int16 width, int16 height, uint8 r, uint8 g, uint8 b
so when connecting via serial, first send a E, then a R to get all the data back from M8
its also important to end with a D
