I am working on a little project but ran into some trouble and cant figure out how to fix it. I recently bought a waveshare 3.2" screen from ebay and it works, but not the way I want it to. I am making a portable raspberry pi with the OS retropie. But the problem is, When I start up the raspberry, it shows me the OS's menu on hdmi, but not on the tft screen. On the tft it only shows the desktop of raspbian, the OS retropie is based on. So basicaly what I want is that I can force the HDMI through the TFT, is this possible? Any other suggestions? Pls help
If I understand your problem you want to get to raspi-config. Open a LX-Terminal and type
sudo raspi-config. This will bring you to the configuration menu. Otherwise, see below.
If you are talking about the "asplashscreen" try this. Navigate here:
sudo nano /etc/init.d/asplashscreen and look for the
do_start() function. Then insert as the first line in the function:
Possibly, you could change these to fix your problem in config.txt.
hdmi_force_hotplug=1 hdmi_cvt=320 240 60 1 0 0 0 hdmi_group=2 hdmi_mode=87 dtoverlay=pitft28r,rotate=90,speed=80000000,fps=60
For more configuration that might help and more explanation, see this post by Adafruit about Retropie and touchscreens. Hope that helps!
