YMDK sell the board and name it "YMD75", however the PCB has "MT84" printed on both sides. + +Most of the code was taken and amended from YMD96 and my port JJ50, which in itself was taken from ps2avrGB and amended by Andrew Novak. + +Note that this is a complete replacement for the firmware, so you won't be +using Bootmapper Client to change any keyboard settings, since not all the +USB report options are supported. + +Hardware Supported: YMD75/MT84 with the ATmega32a chip. +Hardware Availability: The YMD75/MT84 PCB is available from YMDK on AliExpress and suchlike. + +This version by Wayne K Jones (github.com/WarmCatUK) + +## Installing and Building + +Make example for this keyboard (after setting up your build environment): + +``` +$ make ymd75:default:program +``` +It should detect the keyboard and set it to bootloader mode automatically, prior to flashing firmware. +I've found that I need to remove the previous build/file before making a new one as it doesn't overwrite it; but this might just be my personal experience. + +See [build environment setup](https://docs.qmk.fm/build_environment_setup.html) then the [make instructions](https://docs.qmk.fm/make_instructions.html) for more information. + +Note that this is a complete replacement for the firmware, so you won't be +using Bootmapper Client to change any keyboard settings, since not all the +USB report options are supported. +In addition you may need the AVR toolchain and `bootloadHID` for flashing: + +``` +$ brew cask install crosspack-avr +$ brew install --HEAD https://raw.githubusercontent.com/robertgzr/homebrew-tap/master/bootloadhid.rb +``` + +In order to use the `./program` script, which can reboot the board into +the bootloader, you'll need Python 2 with PyUSB installed: + +``` +$ pip install pyusb +``` + +If you prefer, you can just build it and flash the firmware directly with +`bootloadHID` if you boot the board while holding down `Left Control` to keep it +in the bootloader: + +``` +$ make ymd75 +$ bootloadHID -r ymd75_default.hex +``` +I dont use windows personally, but the following is from ymd96 regarding flashing the atmega32a: + +Since the YMD75/MT84 uses an ATmega32a chip instead of the 32u4, you need to download [HIDBootFlash v.1.0](http://vusb.wikidot.com/project:hidbootflash) for Windows. If anyone knows of a Linux/Mac bootflasher that works, edit this readme! +On Windows, I use [MINGw](http://www.mingw.org/) to compile the keymaps. On Linux or OSX you can simply use the terminal. + +Once you have those two pieces of software: +Build the keyboard with +``` +$ make ymd75:default +``` +If you make your own layout, change the `default` word to whatever your layout is. + +And flash the compiled hex file with `HIDBootFlash`. Simply put the board in flashing mode by plugging it in while holding the key below the top right key, and click `find device`. Then you can specify the .hex file and flash it to the device. + + +## Troubleshooting + +1. Try plugging the board in while pressing `Backspace` (`Key below the top right key`). This will force it to boot only the bootloader without loading the firmware. Once this is done, just reflash the board with the original firmware. +2. Sometimes USB hubs can act weird, so try connecting the board directly to your computer or plugging/unplugging the USB hub. +3. If you get an error such as "Resource Unavailable" when attemting to flash on Linux, you may want to compile and run `tools/usb_detach.c`. See `tools/README.md` for more info. +4. I was occasionally finding that I wasn't flashing changes that I was making to my keymap. If that happens, remove the previous build and simply force rebuild by making with: +``` +$ rm ymd75_default.hex +$ make -B ymd75:default +$ make -B ymd75:default:program +``` + + + |
