I am using m8c with great success. Thank you!

I have installed it on a norns and it functions with a forwarded X display, however it is very laggy and the keyboard controls are often doubled. I'm not asking for a fix.

I wondered if a Text mode could be done - possibly with ncurses. I can try myself, but I can't figure out how to interpret the display stream to convert over to a text display. I may be completely mistaken in taking this approach, but I wondered if you thought it may be possible and point me in the right direction.

SDL seems to forget what was on the screen when window is resized in Windows

hello,

After a while using m8c I've found it was easier to deal with this alternative keymap:

key_select_alt=29
key_start_alt=27
key_opt_alt=4
key_edit_alt=22

Similarly, with a controller like those cheap USB SNES like:

gamepad_select=0
gamepad_start=1
gamepad_opt=2
gamepad_edit=3

why?

because the original DirtyWave M8 is using this key setting:

This way, with this keymap, you'll get a closer experience. On the original PC keymap the row with option+edit and the row with shitf+play are inverted, which is a bit confusing when reading the documentation with the shortcuts for example...

just my 2 cents

btw many thanks for m8c, it's an awesome frontend to my teensy!

Hiya

I'm getting the spinning cube on a Anbernic RG351V

What device is disconnected and how might I fix it?

I am trying to run m8c on a GamePi43 device https://www.waveshare.com/wiki/GamePi43 using the RetroPie mkarcadejoystick driver https://github.com/recalbox/mk_arcade_joystick_rpi. The joystick works fine with any other app and I would greatly appreciate some help in making it work with m8c.

I'm building m8c for Android downstream, with a hope of upstreaming it at some point if there is interest. Unrooted Androids do not seem to have direct access to serial ports, instead you get the USB device you want to use in Java side (dealing with permissions etc.),open a connection, claim the CDC/ACM interfaces and pass the file descriptor to the native code where you can communicate with the device.
Since libserialport doesn't deal with file descriptors, something like libusb needs to be used instead.

So my proposal is to:

• Move dependencies to libserialport.h to one file
• Create more abstract functions to deal with serial init, read and write. Something that doesn't have dependencies on libserialport.h
• Use something like #ifdef LIBSERIALPORT in the .c files to turn libserialport dependency on and off.

I'm not a C developer in any capacity so ideas are welcome.

This is something I'm going to do anyway so it's not a request for somebody else to do it, more like a check to see if I should attempt to upstream it as well.

Line
brew update && brew install -y git gcc make libsdl2 libserialport
should be
brew update && brew install -y git gcc make sdl2 libserialport

Is there a way to add alt mappings, to allow for a function to be mapped to two buttons?

Using snprintf instead of sprintf could help to avoid zero-termination / buffer overflow problems.

please delete, problem solved

Setting fullscreen = true in /home/<username>/.local/share/m8c/config.ini doesn't trigger the program to start in fullscreen mode and disables the alt + enter control.

OS: Debian GNU/Linux 11 (bullseye)

Thank you for this client!!. I have a problem when using the FM synths. As soon as I set complex waveforms, the gui disappears but the sound stays on. This happens particularly quickly when using noise. I can start the m8c again from the terminal, but after a few seconds it crashes again. Could it be because I am using an RPi4 instead of an RPi3b+?

Hi! I'm just getting started with my Raspberry Pi headless setup with an 8BitDo NS30 pro controller. In qjoypad, I can see my buttons are reflected exactly as they should be, and I can press shift and option at the same time and see them both light up.

However, in m8c, this combo does not seem to do anything. Pressing and holding both at the same time, my arrows move between screens as if only shift was held. No magenta highlight as I get with the keyboard. I notice [SHIFT]+[EDIT] does paste as expected, so not all combos seem to have this issue.

Have I missed something? Any guess what might be happening? m8c seems awesome, otherwise. I really appreciate the work going into it!!

I have Jackd routing the audio, I added the commands from the readme in a script and it works when I run the script manually. However when I try to add this script to be executed at boot by rc.local it just doesn't want to run. Is there some trick to this? It's pretty annoying to have to initiate the script manually in order to get some sound after every restart. Any tips?

There shouldn't be much platform-specific code in the program except for reading/writing serial, using https://sigrok.org/wiki/Libserialport might work to make the program cross-platform?

I've seen a couple people have this issue with Pop_OS, which must be doing something a bit differently than Debian in its serial setup.

I can confirm that the device is readable and writeable by the user, since screen and minicom work fine.

I'll investigate and look towards implementing a fix.

Per https://discord.com/channels/709264126240620591/879940212690669578/982689334090158120
(@aquarat on discord) discovered that using the dirtyflag in https://github.com/laamaa/m8c/blob/main/render.c#L221 seems to cause very low framerate on Odroid Go (Advance,Super) devices running Ubuntu 18.04 distro from the vendor (Hardkernel).

I'm not sure why this would be the case, but for the time being, @laamaa would you be open to having a config flag to allow disabling the use of that if, maybe even a C preprocessor macro for now? defaulted to off but so anyone building for these devices could set it rather than maintaining a fork.

Hello!
Try m8c on WSL2 - got CRITICAL: Cannot find a M8.
In WSL m8 serial /dev/ttyS*
https://www.scivision.dev/usb-tty-windows-subsystem-for-linux/
Is it possible to run m8c on Windows?

Hi! Thanks a lot for that software :)
Using a gamepad, it would be great to be able to use the right stick to navigate through menu (therefore acting like a SELECT+DPAD). Would that be difficult to implement?

Not sure if this can be done in any useful way, but it's worth looking into

I quite often get the following error and m8c disconnects. I've managed to reproduce this when using samples, it'll happen after about 20 seconds of playback. Other times it appears out of nowhere with only using the FM synth.

Is there any way to get more information on what caused the error? I thought it might be the SD card isn't up to scratch but I'm using a Sandisk Ultra 32GB and used the SD card formatter to format it in Fat32 format.

CRITICAL: Error -2 reading serial

EDIT:

I'm using MacOS Monteray on a decent spec recent i7 with far too much ram. I'm not sure the machine is the issue though.

I'm running M8_V2_5_3B_HEADLESS

Hey there! I'm trying to get this working on the Steam Deck but my linux-fu isn't strong enough. What would I need to do to get it to work on Arch Linux?

Thanks!

The application should keep correct aspect ratio when using full screen on widescreen displays

Now that there's audio support, it would be nice to be able to record video clips directly with the software. Libffmpeg might be a good candidate?

Try adding a little delay so that the screen isn't reset on every pixel..

I've mapped gamepad_quit to one of the buttons on my gamepad (GPI Case 2 which appears as an xbox controller), but it doesn't do anything. If I pair a different control, like edit, to the same button, that works, so the button is correct.

so as a Side effect of trying to get m8c to run on the pocketchip, I gave it a go on my laptop and it compiles fine and everything it finds the m8 then I get

ERROR: Error: Failed: Inappropriate ioctl for device

not really sure what causes this. This doesn't happen on debian 11. I may try my other machine running lubuntu

Thanks for creating m8c! It's an amazing experience to try it out together with a Teensy 4.1 on Linux, and a great way to check out the Dirtywave M8 and "try before you buy".

I tried packaging m8c for Termux, but apparently packaging libserialport was not straightforward: termux/termux-packages#9315

I also tried packaging m8c as an SDL2 application, for Android (as an .apk file), but including SDL2 in the various available Android build systems was more of a hassle than I had anticipated.

This is a feature request for somehow, either through Termux or as an Android application, support m8c on Android.

Hi !

First of all, thank you to the creators of this great software.

On my Zorin 16 OS, it works very well but crashes every time I go to the screen where you select which parameter will be parameter-locked (the screen with the names of all available parameters). I hope I'm clear... I know it's M8c crashing and not the M8, because the music continues to play, and when I relaunch m8c I'm still on the same page (and it crashes again after a few seconds if I don't leave this screen very fast).

Thank you !

Win32, Win64, Linux and OSX would be nice to have automated!

I'm getting my headless M8 up and running on a raspberry pi, with the intent of having a fully standalone unit. In pursuit of this, I have set up the m8c application to run at startup, and I'm trying to find a way to get it to start automatically in fullscreen mode, as the display I'm using is a Hyper Pixel 4 inch display that hangs off the GPIO on the host Pi, and screen real estate is limited. I have tried changing the fullscreen flag to true in m8c's config.ini, which didn't work. Also tried changing the c.init_fullscreen variable in config.c to "1", with no luck, either. Additionally, I have tried executing m8c with flags from the command line (-fs, -maximize, -fullscreen; all with both one and two dashes preceeding), which had no effect.

Any thoughts on how I can get m8c to start up in fullscreen when starting the application from a linux autostart .desktop entry? Thanks so much for making this project available! Loving my headless m8, so far :-D

maybe I'm doing something wrong?

• "m8c-20220830-macos.zip" download from https://github.com/laamaa/m8c/releases/tag/v1.3.0

Hey! I wanted to mention I had heard this wasn't working great on anything older than a RPI4. I had a spare RP2 that I wanted to attempt to run this on because I just didn't think it should be particularly resource intensive and found that it was maxing the CPU and barely functional. It looks like the Accelerated SDL2 render is the cause.
I switched the SDL renderer const in renderer.c to SDL_RENDERER_SOFTWARE and now it runs perfect on a PI2 using only like 10% CPU.
Thanks!
Kasey

Probably some junk in the textures, make sure that they're emptied on screen init

If a config.ini isn't found, the program should be able to create one with the default values.

Currently config.ini and gamecontrollerdb.txt reside in the same directory as the application. It would be better to store them in standard directories for support files, this can be done with SDL2's SDL_GetPrefPath function.

attempting to compile on a arm device running debian Stretch this is use KainXKitsune on the discord. I get errors of undefined reference to and a lot of them are egl_window "wl_egl_window_get_attached_sized" for example.

Hi.

I like your project and wanted to create an AUR (Arch Linux user repository) package for it. But that requires me to put the package license in the metadata but I could not find information on which license this project uses.

Something like Schism Tracker has, https://github.com/schismtracker/schismtracker/tree/master/sys/macosx/Schism_Tracker.app/Contents

I have no idea how this should be constructed though since I have 0 experience on OS X dev tools :/

I have an 8bitdo controller, with the following mappings

Controller,a:b0,b:b1,back:b6,dpdown:h0.4,dpleft:h0.8,dpright:h0.2,dpup:h0.1,guide:b10,leftshoulder:b4,leftstick:b8,lefttrigger:a2,leftx:a0,lefty:a1,rightshoulder:b5,rightstick:b9,righttrigger:a5,rightx:a3,righty:a4,start:b7,x:b2,y:b3,platform:Mac OS X,"

How do I map the h0.8 etc ones? It doesn't seem to support them in the ini. If I map the directions to a regular button it seems to work as intended.

Some users have reported problems with starting m8c:

INFO: Looking for USB serial devices.
INFO: Found M8 in /dev/ttyACM1.
INFO: Opening port.
INFO: Enabling and resetting M8 display
INFO: Reset display

and after that, the program returns into terminal.

Sometimes the error might look something like:

INFO: Reading config /home/jonne/.local/share/m8c/config.ini
INFO: Writing config file to /home/jonne/.local/share/m8c/config.ini
INFO: Looking for USB serial devices.
INFO: Found M8 in /dev/ttyACM1.

ERROR: Error: Failed: Inappropriate ioctl for device

This seems to be a conflict with some Linux kernel versions and libserialport (sigrokproject/libserialport@6f9b03e) and the error can be mitigated by building libserialport from sources:

1. Remove existing libserialport packages
   for example, on Debian based systems apt-get remove libserialport0 libserialport-dev
2. Build libserialport from source code according to instructions in https://github.com/sigrokproject/libserialport
3. Rebuild m8c

I know it probably won't and I doubt it has been tested yet but does anyone have and Idea if it will work on the Steam Deck from Valve? I should have mine in the coming months and I feel like it would be the perfect device to run the M8 headless.

The configuration could be initially done through a config file, at some point possibly from the application.

Is it possible to compile M8C to run on Windows 32 bit systems? If so, how would I go about that?

Thanks!
