Hello, I recently bought the waveshare 3.5B revision 2 screen to play around with. However, the driver in webconf only shows a black screen. The only one that seems to work is the piscreen v1 but the colors are inverted.
I was able to calibrate it with the tool under the Admin menu and it works pretty well aside from the inverted colors. I seen this was asked before in another topic here but the solution didn’t work for me.
I was curious though and decided to install the driver from the manufacturer to see if the proper colors would show. The machine reboots and I can see the command line with proper colors, but it never gets into the zynthian UI after this. I’m only able to login and get to the terminal.
I also struggled with this display and did the same as you to no avail. I had to start with a fresh card and copied the official overlay to the boot folder:
so, run a
git clone https://github.com/waveshare/LCD-show.git
cd LCD-show/
Select the display in webconfig and you should be good to go.
Oh, forget to mention: although the display works as it should, touchscreen will be off. Calibration tool didn’t work for me, so I had to manually put in the config. But honestly it is no fun running zynthian with a touch display, so I wouldn’t bother! If you use usb for midi in and audio out there are enough pins free to wire encoders directly to the pi (at least I hope so, had only two around and waiting for the other ones)
