• USB QMK keyboard running

  pcadic • 10/19/2021 at 16:44 • 0 comments

  Today , between 2 patients appointments, I was able to flash the ATMEGA32U4 of the pcboard. It worked like a charm at first book. Have a look at QMK QMKTools to understand how to flash the HEX file.  (you have the .hex file in the file area of this article)

  First tests show a working QWERTY KB with my dev laptop.

• QMK Compatible KB ? ATMEGA32u4

  pcadic • 10/13/2021 at 12:55 • 0 comments

  yesterday we rebuit the keyboard (the old one had a circuit short which was hard to fix, due to a bad soldering technique). 

  We were able to flash the ATMEGA32u4 like a charm and run a sketch uploaded via ARDUINO IDE software. Good!

  Now we are preparing the QMK config files .  Installation of QMK was made under linux following this Guide.   

  We created the new kb called BLAKRPI with ./util/new_keyboard.sh bash script and followed this guide.

  Below, the schematic showing how the ATMEGA32U4 is wired

  "Cyberpunk computing"'s forum post was also of great help.   We were able to  setup the firmware.

  # MCU name
  MCU = atmega32u4
  
  # Bootloader selection
  BOOTLOADER = caterina
  
  # Build Options
  #   change yes to no to disable
  #
  BOOTMAGIC_ENABLE = lite     # Enable Bootmagic Lite
  MOUSEKEY_ENABLE = no       # Mouse keys
  EXTRAKEY_ENABLE = no       # Audio control and System control
  CONSOLE_ENABLE = no         # Console for debug
  COMMAND_ENABLE = no         # Commands for debug and configuration
  # Do not enable SLEEP_LED_ENABLE. it uses the same timer as BACKLIGHT_ENABLE
  SLEEP_LED_ENABLE = no       # Breathing sleep LED during USB suspend
  # if this doesn't work, see here: https://github.com/tmk/tmk_keyboard/wiki/FAQ#nkro-doesnt-work
  NKRO_ENABLE = no            # USB Nkey Rollover
  BACKLIGHT_ENABLE = no       # Enable keyboard backlight functionality
  RGBLIGHT_ENABLE = no        # Enable keyboard RGB underglow
  AUDIO_ENABLE = no           # Audio output

   rules.mk 

  Then we design the layout for the 60 keys

  #pragma once
  
  #include "quantum.h"
  
  /* This is a shortcut to help you visually see your layout.
   *
   * The first section contains all of the arguments representing the physical
   * layout of the board and position of the keys.
   *
   * The second converts the arguments into a two-dimensional array which
   * represents the switch matrix.
   */
  #define LAYOUT( \
  K000, K001, K002, K003, K004, K005, K006, K007, K008, K009, K010, K011, \
  K100, K101, K102, K103, K104, K105, K106, K107, K108, K109, K110, K111, \

  ) { \
  { K000,  K001,  K002,  K003,  K004,  K005,  K006,  K007,  K008,  K009,  K010,  K011 }, \
  { K100,  K101,  K102,  K103,  K104,  K105,  K106,  K107,  K108,  K109,  K110,  K111 }, \
  { K200,  K201,  K202,  K203,  K204,  K205,  K206,  K207,  K208,  K209,  K210,  K211 }, \

  hi all.

  I was able to setup the GFX interface. You will need the may2020 raspbian image to be able to get it running, then update/upgrade from it.
