<p><strong>This is chapter is currently work in progress,
|

|
|
it will re-appear once it is more complete</strong></p>
|
||
|
|
<p>This section describes the internals of the RTIC framework at a <em>high level</em>.
|
||
|
|
Low level details like the parsing and code generation done by the procedural
|
||
|
|
macro (<code>#[app]</code>) will not be explained here. The focus will be the analysis of
|
||
|
|
the user specification and the data structures used by the runtime.</p>
|
||
|
|
<p>We highly suggest that you read the embedonomicon section on <a href="https://github.com/rust-embedded/embedonomicon/pull/48">concurrency</a>
|

|

before you dive into this material.</p>
