TMDS243EVM: If want to use RS485 in my app, which demo can I refer to?

Hello Hongkai xiao,

There is no support for RS 485 communication on the EVM.

We need the level shifter to translate the UART levels to RS 485 levels, which are not there on the EVM.

So, this functionality directly does not work out.

You do one thing there is that MCU UART 1 pins are available on the MCU header, and you use these pins.

Use the UART with the MCU UART 1 example from the MCU + SDK.

Externally, you need to connect the RS 485 Transceiver to the MCU UART.

This way you can make it work for the RS - 485 demo.

We need to set the mode selection for RS -485 communication support and for that, you can check for the TRTM chapters below.

Please let me know if you need any help .

Regards,

Anil.
