digitalmars.D.announce - [Hackathon] ARM Cortex-M LCD Demo

A simple demonstration using D to bare-metal program and ARM 
Cortex-M microcontroller.  Full description with pictures and 
even a video can be found here:  
https://github.com/JinShil/stm32f42_discovery_demo/blob/master/README.md

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.

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?

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.
