USART3，USART4 how to use
2020-12-20
DearI use the STM32H7B3I-DK this board,and I read the manual.The instruction says I can use CN11 digital pin name D0 and D1,but D1 is (USART4_TX),D0 is (USART3_RX).Then how do I use the USART3, because do not find USART3_TX

Sorry,I do not understand what you mean.So D0 and D1 are both USART3 or USART4?
