=====
On the STM32F429I-DISCO board, because of pin mappings to support the
onboard SDRAM and LCD, the only UARTs that has both RX and TX pins
avilalbe are USART1 and UART5. Other USARTS could be used for RX or TX
onboard SDRAM and LCD, the only UARTs that have both RX and TX pins
available are USART1 and UART5. Other USARTS could be used for RX or TX
only, or they could be used for full-duplex if the other pin functions
aren't being used (i.e. LCD or SDRAM).
