That's interesting. Might do some DIY robotics in future.
I would like to create a hardware abstraction layer for the BeagleBone Black (the board I am playing around with in my spare time which is very beginner friendly and flexible w.r.t. to hardware interfaces due to a lot of "capes" https://beagleboard.org/cape which are available for it) comparable with this HAL for embedded boards in Go https://github.com/kidoman/embd. This would allow people with little "low level" programming experience to play around with D on embedded linux as well. In the beginning porting some of the C++ classes from https://github.com/derekmolloy/exploringBB/tree/master/chp06 could be a good starting point. Or does someone know another HAL implementation which could be more suitable as "template" to start with? However as always... motivation is high, time is limited. Feel free to join :)
