USB OTG Core ID

The USB OTG Core ID is a unique identifier that is used by USB On-The-Go (OTG) devices to determine which device is the host and which is the peripheral. The Core ID is a 5-bit value that is transmitted on the USB bus during the initial handshake between the two devices. The device with the lower Core ID value becomes the host, and the device with the higher Core ID value becomes the peripheral. This allows for two-way communication between devices, even when neither is specifically designed to act as a host.

STM32 USB FS Core and USB OTG Core
STM32 USB FS Core and USB OTG Core are two different USB cores available in STM32 microcontrollers.
The USB FS (Full-Speed) core is a simpler version of the USB OTG (On-The-Go) core and is designed for devices that only need to operate as a USB device, such as a USB flash drive or a USB keyboard. The USB FS core supports USB 1.1 and USB 2.0 Full-Speed (12 Mbps) communication.
On the other hand, the USB OTG core is a more advanced USB core and is designed for devices that need to operate in both USB host and device modes, such as a smartphone or a tablet. The USB OTG core supports USB 1.1, USB 2.0 Full-Speed (12 Mbps), and USB 2.0 High-Speed (480 Mbps) communication.
Both cores are available in STM32 microcontrollers and can be used depending on the requirements of the USB device application.
usb otg 驱动
USB OTG(On-The-Go)驱动是一种用于支持USB OTG功能的驱动程序。USB OTG是一种标准,允许设备在主机模式和设备模式之间切换,以便设备可以充当USB主机或USB设备。
要使用USB OTG功能,您的设备需要支持OTG硬件,并且需要正确的驱动程序来启用和管理OTG功能。这些驱动程序通常由设备制造商提供,并且通常与设备的操作系统集成在一起。
对于Android设备,大多数设备已经内置了OTG驱动程序,并且自动启用了OTG功能。只需连接OTG适配器到设备的Micro-USB或USB-C端口,然后连接外部USB设备,如鼠标、键盘、闪存驱动器等,即可使用。
对于其他操作系统或特定设备,您可能需要在设备制造商的支持网站上查找和下载相应的OTG驱动程序。
总之,要使用USB OTG功能,您需要确保设备支持OTG硬件,并安装正确的驱动程序。请注意,不同的设备和操作系统可能有不同的配置和要求。
