今日も成果が微妙

android

月曜は色々と割り込み (?) が入るので何もできん。晩にも社用にて会食だったりなんかして、調べる時間が全然無いよう。

とりあえず

Ubuntu な端末に BU-353 を差してみて udevadam な出力を確認。

# udevadam monitor --kernel --environment
monitor will print the received events for:
KERNEL - the kernel uevent

ええと、

  • PRODUCT=67b/2303/300
    • これ、udev.rules な以下に合致している模様
SYSFS{idVendor}=="067b", SYSFS{idProduct}=="2303", SYMLINK="gps"
    • このルール的には /dev/gps ができる模様

あと、どこかに stty -F /dev/gps 4800 してみれ、との記述があったのでヤッてみた。

なんか場所がバレそうな気もしますが自宅でないのでスルー。なんとなく実機側で 4800bps な転送速度にしてあげる事ができれば認識可能なのかなぁ。
今日はもうタイムアップだったりするので、明日以降でがっつり掘らせて下さひ。

ああ

時間が無いよう (とほほほ
