For some time now I have been doing projects (or should I rather say "been playing around") with AVR microcontrollers. Both in the form of different types of Arduinos but also in stand-alone projects (including the USB KVM and a battery powered ATTINY85 board, which I still haven't written a post about). For the most part I really like these microcontrollers, they are versatile, low powered and the development tools available are excellent (and importantly, available on all major platforms). However, In one of my latest projects I encountered a situation where AVRs just might not be enough. What I wanted to do was to capture images from a digital camera module (OV7670) and process them to determine movement speed and direction. While it might in theory be possible to do so on an ATMEGA microcontroller or similar, the small amount of memory available would make such an operation tricky at best. At that point I started looking for a more powerful microcontroller, and o...
