【Let's split】qmkの書き込み
レツプリ基板が全然届かなくて暇なのでArduino pro microにファームを焼いた
qmkとはQuantum Mechanical Keyboard Firmwareのことらしい
https://github.com/qmk/qmk_firmware/blob/master/readme.md##customizing-your-keymap
・環境
Ubuntu 16.04 LTS
avrdude (sudo apt-get install avrdude でインストールできるがいつのまにかインストールされていた)
git
・基本的なやりかた
1 gitディレクトリを作る
2 qmk_firmwareを取得する
参考 https://github.com/qmk/qmk_firmware/tree/master/keyboards/lets_split
git clone https://github.com/qmk/qmk_firmware.git
3 qmkのディレクトリに移動する
~/git/qmk_firmware$
4 makeする
make lets_split/rev2:default
このようなログが出る

5 qmk_firmwareディレクトリにhexファイルができていることを確認する
lets_split_rev2_default.hex
6 Arduino pro microをUSBで接続して次のコマンドを実行する
USB端子壊してしまう前にこういう3個セットなど購入して予備を用意しておくべき
git/qmk_firmware$ make lets_split:default:avrdude
これは公式の説明と異なるので注意※
数日後に公式が修正されていた
するとこのようになる

と出てリセットの待機状態になる
7 この状態でArduino pro microの左上の並んだ2つの穴のGNDとRSTをショートさせる
スイッチを使うならリセットは1回押すだけで良い

・自分のキーマップをつくる
1 新しいキーマップのファイルを作る
/git/qmk_firmware/keyboards/lets_split/keymaps
にあるdefaultディレクトリーをコピーして適当な名前をつける
例:mykeymap
2 keymap.cのキーマップを好きなように編集する
3 buildする
$ make lets_split/rev2:mykeymap
4 git/qmk_firmwareディレクトリにhexファイルができていることを確認する
lets_split_rev2_original1.hex
5 Arduino pro microをUSBで接続して次のコマンドを実行する
git/qmk_firmware$ make lets_split:mykeymap:avrdude
6 リセット待ちになったらリセットする
リセットはGNDとRSTをショートする
7 処理が進み、「avrdude done. Thank you.」と出たら完了
・失敗した時
自分は机の上にあったクリップを使ってショートさせたら、ショートする時間が長すぎてエラーavrdude: ser_open(): can't open deviceが出た。
Detecting USB port, reset your controller now................................. Detected controller on USB port at /dev/ttyACM0 avrdude: ser_open(): can't open device "/dev/ttyACM0": No such file or directory avrdude done. Thank you. tmk_core/avr.mk:172: recipe for target 'avrdude' failed make[1]: *** [avrdude] Error 1 Makefile:528: recipe for target 'lets_split:default:avrdude' failed Make finished with errors make: *** [lets_split:default:avrdude] Error 1
はじめはショートさせる時間が長すぎることが問題だとわからず、調べていたら権限追加(https://stackoverflow.com/questions/40951728/avrdude-ser-open-cant-open-device-dev-ttyacm0-device-or-resource-busy)が足りないと思いやってしまったが、まだ同じエラーが出てショートさせる時間だと気づいた。
$ sudo adduser <username> dialout $ sudo chmod a+rw /dev/ttyACM0
※注意
公式のFlashのページ(https://github.com/nicinabox/lets-split-guide/blob/master/flashing.md)を見ていると
make lets_split-rev2-YOUR_KEYMAP_NAME-avrdude
とあり、-avrdudeなんてファイルできてないしなんでこうなるのかわからないまま実行したら、当然エラーになった。
make: *** No rule to make target 'rev2-default'. Stop.
全然わからず調べていたらこのブログ(http://hanocha.hateblo.jp/entry/2017/11/23/154320)に
3. 以下のコマンドを実行 # make lets_split:default:avrdude
とあり、ようやくわかった。
