Hello Everyone,
I’m working on a project where I’m interfacing a DWIN LCD with my STM32 microcontroller using UART. The UART TX and RX lines from the STM32 are connected to the RX and TX lines of the DWIN LCD, respectively. I’ve ensured that the baud rate, parity, stop bits, and other UART parameters are correctly configured on both devices. However, I’ve run into an issue: when both the TX and RX lines are connected, the LCD seems to receive dummy or incorrect values. Interestingly, if I disconnect the TX line and only leave the RX line connected, the LCD receives the correct data without any problems.
Any insights or suggestions on what might be causing this problem and how I can resolve it would be greatly appreciated. Thank you in advance for your help!
Let me know if you need further adjustments!
