uart communication between stm32 and stm32

[이정훈.1]

Hello

I want to use two STM32F407 MCUs to enable bidirectional communication via UART communication with each other.

I would like to have a two-way communication that turns on and off each other by installing a switch and an LED, respectively. Thanks a lot for your advice. thank you.

Aren't there literally hundreds of UART examples you could use as a starting point?

Have a common ground and cross-connect the RX and TX between the two STM32 parts

Hello @�?� 정훈​,

I recommend you referring to the UART examples provided by the STM32CubeF4.

For example you can find them under the "STM32CubeF4/Projects/STM32F401-Discovery/Examples/UART" root.

Please follow the instructions mentioned in the readme file.
