Mechmini V1

A 40% ortholinear/staggered keyboard, that was originally bootmapper and can be ported to QMK following this readme. This version is no longer in production More info on MECHKEYS.

Keyboard Maintainer: QMK Community Hardware Supported: Mechmini 1 PCB
Hardware Availability: Version 1 (Bootmapper) no longer in production MECHKEYS

Make example for this keyboard (after setting up your build environment):

make mechmini/v1:default

See build environment setup then the make instructions for more information.

Mechmini Notes

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.

Installing

First, install the requirements. These commands are for OSX, but all you need is 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

Then, with the keyboard plugged in, simply run this command from the qmk_firmware directory:

$ make mechmini:program

If you prefer, you can just build it and flash the firmware directly with bootloadHID if you boot the board while holding down L_Ctrl to keep it in the bootloader:

$ make mechmini
$ bootloadHID -r mechmini_default.hex

Troubleshooting

From my experience, it's really hard to brick these boards. But these tricks have been useful when it got stuck in a weird scenario.

  1. Try plugging the board in while pressing L_Ctrl. 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 errors happen with ./tmk_core/common/avr/suspend.c it is likely you implemented a RGB underglow sleep setting previously. Simply comment out the following code found under void suspend_wakeup_init(void):
ifdef RGBLIGHT_ANIMATIONS
    rgblight_timer_enable();
    _delay_ms(50);
    rgblight_set();
#endif

So that the resulting code should know reflect:

/*#ifdef RGBLIGHT_ANIMATIONS
    rgblight_timer_enable();
    _delay_ms(50);
    rgblight_set();
#endif*/
