初期プログラムでは、初期化関数だけ実行されます。Lチカを一度行い無限ループでなんの処理も行われません。 周辺機能を使用する時は、ファイルを確認していただければと思います。 また、モーターの回転方向等については、一意に決定することのできないため各自で書き換えていただければと思います。 該当する関数は、controlMotorです。
使用しているモーターはドローンモーターのφ8.5mm,長さ20mmの8520モーター(7.4V)、ピニオンギアはkkpmoで購入した歯数20、モジュール0.3、穴径1.0mm、 スパーギアはMisumiのメカニカル加工部品の歯数80、モジュール0.3、穴径18.0mmです。

Rokisi: common questions
What microcontroller does the Rokisi use?
The Rokisi is built around the STM32F405RGT, from the STM32 family.
How big is the Rokisi PCB?
The Rokisi measures 79.1 × 82 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Rokisi?
73 components, from 33 distinct parts. The full bill of materials is listed on this page.
Where can I download the Rokisi design files?
From the mdumas2/rokisi repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Rokisi design in my own project?
Yes, under the terms of its BSD-3-Clause license, which mdumas2 chose for the repository.
Can I test firmware for the Rokisi without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
