STM32 microcontrollers are not limited to just acting as USB devices they can also function as USB hosts. ![]() Stm32 usb host: connecting usb peripherals Once the driver is installed, the STM32 device can be connected to the host computer via USB, and the Virtual COM Port will be recognized and available for communication. STMicroelectronics provides driver packages compatible with Windows, Linux, and macOS, ensuring cross-platform support for your projects. Installing the virtual com port driver for stm32īefore using the Virtual COM Port feature on STM32, it’s essential to install the necessary driver on the host computer. This enables the STM32 microcontroller to appear as a standard COM port on the host computer, making it compatible with various terminal applications and programming environments. This feature simplifies the process of establishing a serial communication link between the STM32 device and a computer.ĭevelopers can utilize the USB CDC driver and libraries provided by STMicroelectronics to implement this functionality seamlessly. One of the essential functionalities offered by STM32 microcontrollers is the ability to create a Virtual COM Port using USB CDC. This allows developers to establish a Virtual COM Port connection between the STM32 device and a computer. STM32 microcontrollers are equipped with USB CDC capabilities, making them ideal for creating USB-based communication solutions. ![]() It enables data transfer between the device and the host (computer) seamlessly. USB CDC, or Communication Device Class, is a standard USB class specification that defines how communication devices, such as modems and serial ports, can be connected to a computer. 5.3 Q3: can i connect usb peripherals to my stm32 microcontroller? Understanding usb cdc (communication device class)
