I'm an owner of an arduino DUE and found it cool, much pins and fast clock. But I was nerver develop, nether with taijuino Due to use the EMAC inside the SAM3X... This is sad because it never use the fast capability of the chip.
I follow another topic the Palliser try to ma a PHY and ethernet library working, but still waiting.
But yesterday, losing my time on internet, I found the data for PIC32MZ 144 pins ! 200MHz, lot of RAM and memory!!! and a seems better developed ethernet lib on MPLAb. and a dev board to test it:
Afer some search, it look like some work have already been done on other pic32mx to match the arduino style like Pinguino
I wonder I it is possible to do some MEGA/DUE compatible board with embebded SD and ethernet, and if people interested for devellopement...
