Last time, we experimented with spiritual blind-sending as a way to theoretically speed up SPI on AVR. While there were lots of fancy oscilloscope traces and impressive demo code, there is nothing like an actual, real, practical application to get people excited. Read on to see how much faster we can make the already highly optimized AdaFruit DotStar library with a little blind-sending action… (spoiler alert – the answer is lots more faster!)
Check out all the DotStar products available in the Adafruit shop.
