This is a great library. I was able to use it with VGA as well as NTSC. There is one issue. If I try to use this in conjunction with USB host library on Arduino Due it works in VGA mode but not in NTSC mode. If I start VGA.beginNTSC() both libraries are going to stop working..
...Just checked the code and I saw this notice:
// Doesn't work well with Native USB
Hm, this seems to be a known fact. Anyway any idea why? Can anybody help?
