STM32 USB OTG FS (On-The-Go Full Speed) is a USB interface that is available on many STM32 microcontrollers. It allows the microcontroller to act as both a USB host and a USB device. This means that it can communicate with USB peripherals such as keyboards, mice, and flash drives as a host, or it can act as a USB device when connected to a computer.
The USB OTG FS interface includes a USB transceiver, a USB controller, and a DMA controller. It supports USB 2.0 full speed (12 Mbit/s) and is compatible with the USB 1.1 specification.
To use the USB OTG FS interface on an STM32 microcontroller, you need to configure the USB hardware and implement the USB protocol stack in software. This can be done using the STM32CubeMX software tool and the STM32 HAL (Hardware Abstraction Layer) libraries provided by STMicroelectronics.
Once configured, you can use the USB OTG FS interface to exchange data between the microcontroller and USB peripherals, or between the microcontroller and a host computer. This makes it a useful feature for a wide range of applications, including embedded systems, industrial control, and consumer electronics.
