USB 多個油門的描述符
[英]USB Descriptor for multiple Throttle
問題描述
我想要一個連接到 PIC 微控制器的 USB 操縱桿。 它只需一個油門和幾個按鈕和兩個軸就可以正常工作。
如何添加另一個油門描述符？

這是我為 ARDUINO Leonardo 編寫的多油門描述符，它在 Windows 10 上顯示了多個油門。請注意，盡管 Windows X8 按鈕和操縱桿設備僅接受 10 Y、方向舵、左制動器、右制動器和最多 3 個油門（我通常使用 2 個）我已將所有 USB HID 值收集到#define值中，以使其更具可讀性。 （我不包括這里的那些）。 您可以在https://github.com/Raptyr/FlightControl找到完整的庫
