Since many people have downloaded examples of controlling USB devices through libusb, I would like to provide an example that does not require libusb for everyone to reference.

前陣子在淘寶買了一塊4.3吋的Panel, Driver IC是用SSD1963, 搭配的MCU是使用STM32F446.
讓螢幕依序顯示RED, GREEN, BLUE.
最近在測試一些nRF52840 BLE相關範例的時候, 總是會遇到在nRF52840 DK Board上面都正常, 但改燒錄在非原廠板子上面就會無法正常的情況.
經過確認後, 發現是因為原廠的nRF52840 DK Board上面有安裝external 32768 振盪器, 而非原廠板子因為成本的關係, 都會將32768拿掉, 因此程式都會當掉在ble stack init的時候.
改法如下, 先找到sdk_config.h, 並修改相關的參數.
