How do you implement USB communication on STM32?
USB Communication Implementation on STM32 (Step-by-Step Guide) 1. Hardware Setup Required Components: STM32 with USB peripheral (e.g., STM32F4xx , STM32H7xx ) USB connector ( Type-C/Micro-B ) + pull-up resistors (1.5kΩ on DP for Full Speed) VBUS detection circuit (optional but recommended) Pin Connections: STM32 Pin USB Signal Description PA11 DM (D-) Data Minus PA12 DP (D+) Data Plus VBUS 5V Input Power Sensing (if used) 2. Software Configuration (Using STM32CubeIDE) Step 1: Enable USB in CubeMX Open STM32CubeMX → Select your MCU Enable USB (OTG_FS or OTG_HS) under "Connectivity" Set mode: Device Mode (for USB CDC/HID/Mass Storage) Host Mode (for connecting to peripherals) Configure Clock Settings : Ensure 48MHz clock to USB peripheral (PLL must generate this) Step 2: Select Middleware (USB Classes) CDC (Virtual COM Port) : For serial commu...
