One more thing,
How i can configure my display to use UART2 for out going commands and UART4 for in ...
UART2 and UART4 are selected according to their own wiring. In general, RX2 and TX2 are UART2; RX4 and TX4 are UART4, subject to the data manual of the LCD screen. UART2 is the default DWIN communication protocol, and UART4 is an extended serial port, which needs to be defined by the OS writing protocol. |
