Gibbs-Duhem writes "The LeafLabs Maple, an ARM device designed to be pin compatible with the Arduino, and with a strikingly similar and familiar development environment, has reached a new milestone — being carried by SparkFun. By swapping the popular 'avr-gcc' compiler with CodeSourcery's 'arm-non-eabi-gcc,' LeafLabs manages to provide a nearly identical programming experience to Arduino despite targeting a completely different architecture. Also, while some Arduino shields are incompatible due to certain capabilities being allocated to different pins, several of them are currently supported and there are more to come."
The most difficult thing in the world is to know how to do a thing and to
watch someone else doing it wrong, without commenting.
