 I agree. This is fantastic work! I am so excited to see this.

Me too! True embedded work should be a sweet spot for D. Too bad we
can't grab 2-3 developers and give them 3-months budget and time to hack
out all the necessary parts for an embedded toolchain,libs,and
methodolgy based entirely on D. Anybody thought of porting relavant
parts of say newlib to D?

I know, random rectangles on a screen is not all that remarkable, but
there's quite a bit of work that needs to be done before one can write
their first pixel.
* Minimal D runtime
* Memory-mapped IO features
* Clock and flash memory configuration
* Software initialization (data and bss segments)
* SPI driver to configure the external LCD controller
* Internal parallel LCD controller configuration
* Hardware random number generator

EVERYTHING is in D. I've had this project on the back burner for a
while, and the Hackathon gave me the excuse I needed to get it done.  I
didn't put a lot of effort into the code because I just wanted to get
something working to prove some ideas I had, and show that D has some
potential in this domain.

I hope you find it interesting.  Ask me anything.

Mike


Awesome work!

Yes, pretty dazz. Mike, if you could hang out a bit on reddit and make an ask 
me anything post, that would help a lot.
