Hi alpha,
Yes I tried that, the lowest resolution is 720*480 and only appears to change the HDMI output, which says to me that the frame buffer isn’t pushing to the GPIO. I’ve tried all sorts of variations using overscan settings and forcing resolution in the boot config but no joy.
I’ll see if I can get the frame buffer copy working as described in your original post. I’m running a Pi4 with the latest raspbian version.

In reply to Michael. I don't remember having those issues when I used the display. If I remember right the frame buffer copy tool did take care of this. But it looks like this tool doesn't work with the latest Raspbian version. Did you try raspi-config advanced option > resolution to change the resolution yet?

Hi,
I realise that this is an old post, however it’s been invaluable in helping me to get my PiShow 2.8″ Touchscreen working. I’ve successfully compiled the driver and the screen is working and touch overlay calibrated.
The issue that I have is that it appears as if it is still defaulting to the native screen resolution of 720 x 480. Any windows on the desktop are only partially displayed and a browser window is cut off on the right.
I’m loading Chromium with a web page and have forced Chromium to a smaller size (DISPLAY=:0.0 chromium-browser –window-size=240,320).

Any suggestions on how to reduce the scale of the desktop to 240×320 (I’m running portrait mode)?

Thanks in advance.
I’ve tried adding Overscan setting to the /boot/config.txt

In reply to Gideon. There is a tar file download on this page with all the souce files... however, if you want a quick start I would suggest to search for 'arduino hid keyboard' on your favorite search engine.

In reply to George. If I had to copy the device overlay to a new Pi I would probably open a ssh terminal window and start a text editor. I love mc with mcedit. Just do a suso apt install mc on the Pi. Now just copy and past from the web page in the ssh window where mcedit was started and save via F2 and exit via F10. Give mc a try to copy or move files, I like it to make my life easier.

Thank you! This is very useful, but how to do the 1st step? How do you add the overlay that you describe. An extra description on that would make this post perfect 🙂
