excerpt: What if you have a graphic display without an embedded controller, and you
  want to drive it with an ARM microcontroller? Turns out that if a DMA is available,
  the task is not so impossible as it first seems. If you’re interested, read
  the article on my website here.<img alt="" border="0" src="https://stats.wordpress.com/b.gif?host=fedetft.wordpress.com&amp;blog=9307626&amp;post=206&amp;subd=fedetft&amp;ref=&amp;feed=1"
