USB HID between Windows and ARM
USB-HID: A standard USB device class originally designed for keyboards, mouse, and game controllers. Its main advantage is that operating systems like windows include built-in drivers, So no additional driver installation is required This "plug-and-play" feature makesHI0 very convenient and easy to Use.
STM32 USB-HID Firmware Development
Define the firmware as a vendor-de fined HID device instead of a standard keyboard or mouse to prevent Windows from intercepting and parsing the data.
Carefully design the Report Descriptor, as it defines the data structure, report format, and endpoint behavior for all HI0 communication.
Strictly follow the defined report length and use fixed-size packets with padding to ensure stable and predictable data parsing.
Ensure proper USB enumeration by correctly handling VBUs detection and power-on timing, So the MCU can respond immediately when connected to the host.
