32x32 matrix with an arduino due

Post by kirberich »

This topic has been discussed already (for the 16x32 matrix at least) here: http://www.adafruit.com/forums/viewtopi ... 47&t=37314
I replied to that post yesterday, but one answer suggested it's better to start a new thread than to add answers to a resolved thread.

My question is, is there any news on the rgb led matrix library being ported to the due? In the thread mentioned above, user avriot posted a simple version of the library for the 16x32 matrix which works with the due (http://avriot.com/?p=393). I've played around with it to make it work with the 32x32 matrix in addition to the 16x32 one (https://github.com/kirberich/RGBmatrixPanelDue), but it has some timing problems when used in conjunction with SerialUSB.

Looking at the original library's code it's obvious a lot of thought and optimisation went into it, and the linked due library seems to be a lot slower than the original library properly ported should be. (On an arduino nano with the original library I get 9fps, with the ported one on a due I get about 28. With the due being more than 5 times as fast as the nano and being 32 bit I, maybe wrongly, expected it to be at least 5 times faster)

So is there any hope the library might get ported soon? And if not, does anyone have any ideas how I could try to get rid of the flickering that affects avriot's library when using SerialUSB at the same time? In fact, if somebody knows where I can find the SerialUSB code that might already help a bit, I can't find it for the life of me.

I don't know of any plans to port that code to the Due at the moment.
