[Andy] stuffed some more RAM onto an Arduino Mega and his three-part walk through on the design, construction, and software is a great read and one of the more ‘hard core’ Arduino builds we’ve seen.
[Andrew] wonders why the SerialUSB() function on the Cortex M3-based Arduino Due is so much faster than Serial() on the Uno or Nano, and shares his observations in this short video. He sets up an ...
