White background on LCD

[bsom]

Any idea why on my freshly built r_e_c_u_r using the 2.1.0 image the background of the LCD is white instead of black?

Same here + the displayed output is upside down relative to the HDMI and composite outputs.

This might be a Waveshare firmware issue. My version of the LCD is a Waveshare 3.5inch RPi (B), which is giving me inverted colors. I'm still trying to figure out how to fix it, but I'm hopeful that this discussion will point me in the right direction: https://raspberrypi.stackexchange.com/questions/113522/3-5-inch-rpi-lcd-with-colors-problem

I was able to rotate the display in config.txt by changing this line:

dtoverlay=waveshare35a:rotate=270

to this:

dtoverlay=waveshare35a:rotate=90

thanks for this info !

i have heard a few reports from people about this inverted display

easiest thing to do i think would be to add an option in the settings that lets you invert the display in the python code.. shouldnt be hard to do and also as bonus maybe some people prefer the white background version in some context...

im not really releasing new versions of this project any more - but can try find time to figure out how to do this inverting since its a request i get every so often.

also while here could add a flip display settings option too - which would do it the same way you describe here with the dtoverlay

Still ppl out here that would love to see rpi4, or 5 builds, thinking/assuming that the video and camera delay times could be greatly reduced…. But completely understand why one would want to avoid  going down the rabbit hole again with an old abandoned project, Cheers!!Mrfugu Sent from my iPhoneOn Oct 28, 2023, at 17:17, cyberboy666 ***@***.***> wrote: thanks for this info ! i have heard a few reports from people about this inverted display easiest thing to do i think would be to add an option in the settings that lets you invert the display in the python code.. shouldnt be hard to do and also as bonus maybe some people prefer the white background version in some context... im not really releasing new versions of this project any more - but can try find time to figure out how to do this inverting since its a request i get every so often. also while here could add a flip display settings option too - which would do it the same way you describe here with the dtoverlay —Reply to this email directly, view it on GitHub, or unsubscribe.You are receiving this because you are subscribed to this thread.Message ID: ***@***.***>
