<p>Hi,</p>
<p>I've been using Assembler, C, C++, C#, Pascal, Delphi, etc. but
never found a language so pleasant to use on larger projects than
Ada - A shame that it's knowledge is not more widespread.
Maintaining a +30 year old code base of +1MSLOC written in Ada
turned out *not* to be a nightmare :-) - On the contrary,
implementing Web Services (SOAP and REST) and Web Clients into
this old code base was actually quite easy. The old saying/joke:
"If it compiles it works" is *almost* right.<br>
</p>
<p>Together with two friends I programmed an autonomous robot in Ada
for a competition - I actually considered RTEMS for the job, but
were too lazy, so we used Linux for this one, perhaps next year
should be with RTEMS?</p>
<p>If you are interested there is a video of its final run (Danish
speaking, sorry):

<p>Anyhow, books, guidance, etc.:<br>

<div>Yes. When you use the RSB to build the RTEMS C and C++
tools, there is an option to enable building Ada support. </div>

</div>
<div>As to learning Ada, GNU Ada (GNAT) was initially
developed to provide a path for folks to learn Ada and make
it more approachable. AdaCore still carries on that mission
and has <a href="https://learn.adacore.com/"
moz-do-not-send="true">https://learn.adacore.com/</a> which
should be a good starting point. Once you are past that, <a
href="https://en.wikibooks.org/wiki/Ada_Programming/Tutorials"
moz-do-not-send="true">https://en.wikibooks.org/wiki/Ada_Programming/Tutorials</a> lists
a number of other tutorials.</div>
<div><br>
</div>
<div>You may be surprised to learn that Ada95 is still very
widely used and introduced some object-oriented support. Ada
2005 added more object-oriented capabilities. Ada 2012 added
the SPARK annotation which allows for formal program
correctness checks. There are obviously other differences
between the editions of the language but those are the
highlights.</div>
<div><br>
</div>
<div>Ada is strongly typed, includes tasking, and was designed
for use in critical systems. A goal is to find errors at
compile or analysis time and not in the field. </div>
<div><br>
</div>
<div>Learn it as a language on a native platform and then try
it on RTEMS once you are comfortable with it.</div>
