Hi,
I am running Raspbian Jessie on a Pi 2 with openFrameworks generating moving visuals on screen. All works well as long as I use an HDMI screen.
I want to show the visuals on a Tontec® 3.5 Inches Touch Screen for Raspberry Pi TFT LCD 480x320 (the version with the screen screwed on to the case, not the screen that forms a flap (can't get this version to work, but never mind)) which connects via GPIO. (http://www.amazon.co.uk/gp/product/B013 ... ge_o01_s01)
I managed to have the 3.5" screen display the visual user interface (desktop) and this works well. But if I run my openFrameworks programme I can see the code loaded in the console but the visuals it generates are only shown via HDMI. I would be very grateful if someone could tell me what I'm doing wrong.
This is how I have set up the 3.5" screen:
sudo raspi-config
enable SPI and reboot
sudo rpi-update
sudo reboot
sudo nano /boot/config.txt
add:dtoverlay=mz61581
sudo nano /usr/share/X11/xorg.conf.d/99-fbturbo.conf
change from HTMI to small screen: option … fb0 to fb1
sudo nano /boot/cmdline.txt
add: fbcon=map10 at end of line and reboot
Thanks,
Ulla
p.s. It may be connected that the command lines shown when booting the Pi do only show via HDMI too. And if I boot to console I do not get anything on the 3.5" screen.
