For the basis of this part, since I’m working on the L6470 chip, I am gonna use some of the material in there and explain what parts of the diagram mean. For example, here is the timing diagram for the SPI coming from the datasheet of the L6470. So here are the 4 wires that are… Continue reading Timing SPI

So in my studies, I came across these cool stepper motor drivers (L6470) which handled a lot of the complex stuff. Now I am one for a challenge, but these drivers were just too good to pass on, as they do just one thing, and they do it really well! So Sparkfun make these boards with… Continue reading Learning to talk SPI
