Hi ,
We are connecting LCD2004 to SRK-V1.4, but we see LCD is not displaying any data.
On probing we found the Enable and RS pins on LCD section are not proper
RS signal is always high and low and EN signal is low
Can you help on this regard what could be pattern of these two signals so that we can compare to working module

Many 20x4 lcd's have their plugs flipped 180 degrees. They often come with a ramps which isn't a issue as they also supply the lcd interface board to suit. But on a SKR 14 It is just one way so you have to get a lcd that maches.
Check your controller 5v is on the lcd 5v pin
The LCD should light up

Hello,
My BTT TFT35 was working fine with SKR 1.4V Turbo using buildfix 2.0x from May, 2020. However, I just tried to update to the latest buildfix repository, and my LCD just continues to "reboot". I think it has something to do with changes made to the pins_BTT_SKR_V1_4 file, but I can't seem to figure it out.
