SKR MINI E3 V2 AND BIGTREE TFT E3 V3

[Talha909]

I have fallowing hard ware

SKR MINI E3V2 BIGTRE TFT 35 V3 RASPBERY PI ZERO

My lcd is not working. There is garbage on the screen. I have done pi zero with spi . There is any solution for that.

And you believe the problem is in the firmware of the TFT because...?

Check the troubleshooting section of the ReadMe.

Please send Maelin configuration, TFT configuration. Send some photos with TFT connection with SKR. As Oldman4U writes, the problem is not in the FW of the display, but in the configuration or connection.

HI. It was working good in marlin. But it does not work in klipper.

[radek8]

You didn't write that it was Klipper. Klipper is probably not fully supported yet ... https://github.com/bigtreetech/BIGTREETECH-TouchScreenFirmware/pull/705

https://www.klipper3d.org/Config_Reference.html#emulated_st7920-display Did you set the klipper here to adapt the simulation ST7920

[Talha909]

Yes
