我想將PIC32MX795F512L拿來做Android open accessory的傳輸
但是Harmony沒有這種傳輸的驅動,所以是否無解?
我有想過要自己做出驅動,但是一起步就卡在以下問題
//**************************************
目標MCU當作USB host,想利用
USB_HOST_RESULT USB_HOST_DeviceGetFirst(USB_HOST_BUS bus, USB_HOST_DEVICE_INFO * deviceInfo);
來取得已經連接android device的desciptor, 但是取出來的結果是錯誤的
//**************************************
手冊在DeviceGetFirst 這個function的說明如下
縮圖


請問有人用過這個function,有成功的範例可以參考嗎 感謝
