Pocket Beagle
Output Text to TFT
This assumes you have the game boy tft shield. Although others that are supported and detected will likely work similarly.
echo "hello" > /dev/tty0
to output to your ssh session, try
echo "hello> > /dev/tty
Output Video to TFT
Download video from somewhere. Resize/scale to small enough resolution (NOTE: this resolution is 128x96, from book Ffmpeg Basics by Korbel)
ffmpeg -i video.mp4 -s sqcif outputsmall.mp4 mplayer -loop 0 -vo fbdev2 outputsmall.mp4
Video should output direct on /dev/tty0
Framebuffer settings:
cd /sys find . -print | grep fb0
There should be an fb0 (graphics) and fbcon (text console) e.g.
root@beaglebone:/sys/class/graphics# ls fb0 fbcon
