Text Upside Down and Backwards. #58

Closed TeStevens315 closed 2 years ago

TeStevens315 commented 2 years ago

Not sure what I did wrong but I have my screen working but the text is upside down and backward/mirrored. The encoder seems to scroll and click fine. It showed up right after the screen firmware upload before it was connected to Fluidd/klipper, although the interface text didn't show up till connected.

I have a tft35-e3 v3 connected to a skr 2 rev b.
I used the precompiled firmware.

My Klipper config for the display

[display] lcd_type: st7920 cs_pin: EXP1_4 sclk_pin: EXP1_5 sid_pin: EXP1_3 encoder_pins: ^EXP2_3, ^EXP2_5 click_pin: ^!EXP1_2

Thanks for any help. Troy

Thats not an actual issue. Some printer manufacturers flip the screen to mount it 180° rotated (See https://github.com/teeminus/NoTouchScreenFirmware/issues/8). You can manuall recompile the firmware with the following line commented in: https://github.com/teeminus/NoTouchScreenFirmware/blob/63a382f294762900353005e41adb902b55045938/src/User/features.h#L11
