CONFIG_UART_STM32

STM32 MCU serial driver

Type: bool

Help

This option enables the UART driver for STM32 family of
processors.
Say y if you wish to use serial port on STM32 MCU.

Direct dependencies

(SERIAL && SOC_FAMILY_STM32) || (SERIAL && SOC_FAMILY_STM32) || (SOC_FAMILY_STM32 && SERIAL)

(Includes any dependencies from ifs and menus.)

Defaults

• y

• y

Symbols selected by this symbol

• SERIAL_HAS_DRIVER

• SERIAL_SUPPORT_INTERRUPT

• SERIAL_SUPPORT_ASYNC if n || n || n

• DMA if UART_ASYNC_API
