TFT 2.4 display communication problem.

Dariusz · 4 Apr 2022, 04:12

I would like to use TFT24 V1.1 display with DUET 2 WiFi board. I have PanelDue displays 5 and 7 in other projects. For this one I needed small display and Duet 3D documentation claims, it should work fine. But there is problem with communication, wich is not continuous but only on power up, error messages, and display mode change. I have opened bug issue on BIGTREETECH-TouchScreenFirmware GitHub, https://github.com/bigtreetech/BIGTREETECH-TouchScreenFirmware/issues/2475. However they claim its Duet 3D board related. May someone help me to solve this problem. There is also Video with description to better understand the issue.

@dariusz get an older build of the TFT firmware from around beginning December 2021. The recent ones have been broken

@dariusz what M575 line are you using?

@jay_s_uk M575 P1 S0 B57600

@dariusz it should be S2 or S3 not S1

@jay_s_uk I was trying also other numbers. It works with 2 also, the same way.

@dariusz So I have tried with several TFT25 firmware including first one which has config_rrf.ini from march 2021. No change, still no continuous communication with duet2 wifi board.
