A very Hacky Holidays

A very Hacky Holidays

[R Tyler Croy]

For me Ada is relegated to being used in my free time, a lot of which I will be
having to hack on things over the upcoming vacation.

I wanted to ask you all what you may/may not be hacking on over the break,
perhaps we could cheer each other on ;)

A little positive reenforcement from your peers can never hurt :)

Ada users don't hack. They engineer.

Let's not jump to any conclusions just yet, you've not seen my code :D

I plan on working on my AWS/GNATcoll "framework".

Progress is slow, but it is moving. :o)

I might also write a short article for the ada-dk.org wiki. It's
probably going to be about how to use a generic to read/parse one
or more configuration files.

extensions project. As requested back in August..

I've started work on GCC 4.5.1 in Debian.  My plan is to add support for
multilib (e.g. the ability to compile both 32- and 64-bit code on amd64
machines).  Then, if all goes well, I'll jump to packaging GCC 4.6 in
preparation for Debian 7 "Wheezy", the successor to "Squeeze".

I intend to do what I aways do: code at the http://framework.kow.com.br
:D Including our own AWS framework - which is about to get a new
release.

Please let us know when you get it working Ludovic. I'll install a
debian inside some virtual machine just for using it. :)

(but I won't switch my Sabayon to debian anytime soon though)

I've been working on an analog synthesizer. My MIDI module 
uses an ATmega168 using code written in Ada (thanks to Rolf's 
AVR-Ada project). My MIDI module seems to be exhibiting key 
rollover problems, which won't be hard to fix. I just need to 
add a nested "Note On" counter, so that I don't prematurely 
execute a physical "Note Off".

The code is written in two tasks (actually threads under AVR-
Ada). The main task processes MIDI events and queues some 
events for the 2nd task. The 2nd task takes care of waking up 
at the right time (via timeouts) and performing ADSR voltage 
changes (DAC # 2) and creation of trigger and gate signals 
(digital outputs). Pitch is also established by sending a 
value to the first DAC, using an SPI interface.

My original code was all C-ish Arduino stuff, which I was not 
very happy with. When I discovered AVR-Ada, I jumped at the 
opportunity and rewrote it all in Ada. It is so much nicer to 
work with and Ada actually pointed out a couple of previously 
hidden bugs (in the C code).

My latest adventures with the recently built VCA synth module, 
can be found below (there is at least one picture of the MIDI 
module in there somewhere):

Wow, sweet project! I was wondering when an AVR-Ada user was going to pipe up
with a neat project.


Does Ada have a theme song you'll be able to pipe through the device?

Talking about peers... I will finish polishing the code for an
implementation of a peer-to-peer transport protocol.  We want to
release the code as open source and this will be the first official
release.  Stay tuned... (and have patience ;-)

Embedded work is so much more fun when using Ada, so I 
couldn't resist.

> Does Ada have a theme song you'll be able to pipe through
> the device? 

I have a bunch of work yet to do before it will be playing any 
tunes. At a minimum I still need to build a VCO (oscillator 
for pitch), VCF (filter) and LFO (low freq oscillator). 
However, it is all great homebrewed electronic fun.

An analog synth (like this one) is normally only capable of 
one note at a time (monophonic). So it will take some multi-
tracked recording to do anything interesting with it.  But 
that is not a problem. All in due time....

My project isn't as cool as Warren's, but here it is anyway:
http://www.flickr.com/photos/66708330@N00/5268293146/

A bunch of leds, which try to be in a tree shape, with a yellow led on
top. Everything is powered by Attiny2313 and AVR-Ada. Code is available
at http://hg.stronglytyped.org/attiny2313-leds/

Currently the processor always runs at full speed (1MHz, delays are
done by busy looping!), but to increase the battery life, I plan to
study how AVR's power saving features work.

Have you seen those addressable LED Christmas light strings? 
You could cause a whole string of lights change according to 
patterns by using some little protocol.

I am trying to finish off my work on my CD/DVD/Blu-Ray-writing
application called "CDVDBurn" which - unfortunately, for all of
you ;-) - only runs on a seldomly-used operating system called
RISC OS.

At the moment, I am adding low-level code for direct USB device
access on the BeagleBoard.

Unfortunately, progress is always slow because most of the time
I am fighting the compiler (an ancient port of GNAT 3.03) to
give me valid ARMv7 binaries...

Is the code available to look at? I'm kind of curious what it looks like to be
honest (never looked at code written for other non-traditional OSes).

The software is not open source. And believe me, the part
that interfaces with the OS is quite ugly - it is a very
thin binding to low-level system calls with register-level
arguments full of addresses and other stuff...

An early (and even uglier) version of the OS interfacing
part is however available in source:
http://www.huber-net.de/adalib.zip

The plan was always to develop a full OOish binding to
RISC OS, but it never happened due to commercial realities,
amount of free time and compiler quality.
