Hi, I am new bie in STM32F4 microcontroller. I am studying STM32 with STM32F4 Discovery Board. I want to program communication via 2 UART on chip. I have read Help documents of Keil IDE but I don't understand and how to use API functions of ARM_DRIVER_UART and RTX Keil. Anyone has a template example or help me some good idea? Thank you in advance,
PS. sorry for my bad English.
