[NV14] horizontal lines #4669

Open nightflasher opened 9 months ago

nightflasher commented 9 months ago

Is there an existing issue for this problem?

What part of EdgeTX is the focus of this bug?

Transmitter firmware

Current Behavior

There are three horizontal lines in the bottom of the screen. They only disappear (fade away) in Bootloader mode, but appear as soon the NV14 is started regularly.

Expected Behavior

No horizontal lines when not needed!?

Steps To Reproduce

Turn on NV14 with edgeTX 2.9.x (maybe earlier version had this too?)

Version

2.9.3

Transmitter

Flysky NV14

Operating System (OS)

Linux

OS Version

Ubuntu 22.04 LTS

Anything else?

Find the display code from Bootloader and check against regular display driving code. IMG_20240222_231820_337 IMG_20240222_225558_169

I've tried different firmware versions, but only down to 2.9.0 beta (or alpha?)

It's probably a defect of the screen or the screen tape, I have something like this in tx16s, banggood refunded me some of the money for it. IMG_20240224_144305_EDIT_1

Yours is defective, you can see shifted pixels, mine just have the lines and are not affecting the Bootloader screen. A hardware defect can't be there in one screen/mode and is gone in another.

Is it only present at the main screen, or when you are in the various settings screens also? If it is only at the main screen, it could be the that the background image needs replacing/updating (it was changed a while ago IIRC due to alpha transparency/blending issues).
