RS485 on TAB5
-
I am trying to use RS485 on the TAB5 main board, whilst there is a connector and SIT3088 I can't find UIFlow support for it, there is for the UART and CAN, but not RS485, have I missed something?

Thanks Robski, this is close, but not really the same thing, The Commu module allows native, and simpler RS485, but I will use Modbus.

Hello @scroggyg
I created a Modbus example for M5Tab5 controlling an ACSSR relay. You can find it in the UIFlow Project Zone: M5Tab5_Modbus_ACSSR_Test_UIFlow2.3.1
Thanks

@scroggyg Hi, the SIT3088 is a "converter" from UART to RS-485. To write/read the RS-485, use the UART1 (TX:20, RX:21).
The setup below works, although I have to store the arrays first somehow, before setting them into my text box (top_box), as the text appears briefly and then disappears ...but I can see I am receiving OK.
I got the tab5 yesterday ...and RS-485 was the first thing I wanted to test it.
