Body
<p>I have one microcontroller but several projects which get compiled from the same source code. I think my scenario is similar to yours, at least to some extent. My solution was inspired by Linux kernel, as well.</p> <h2><code>config.h</code></h2> <p>All source code which needs to get access to some configuration parameter simply includes an header file called <code>config.h</code>.</p> <p><code>config.h</code> consists of just one line:</p> <pre><code>#include <config/project.h> </code></pre> <h2><code>project.h</code></h2> <p>I have several configuration header files, one per project. A <code>project.h</code> consists of macro definitions with values such as <code>true</code>, <code>false</code>, or constants:</p> <pre><code>#define CONFIG_FOO true #define CONFIG_BAR false #define CONFIG_TIME 100 </code></pre> <h2><code>check.c</code></h2> <p>This file checks configuration parameters for correctness: - all parameters <strong>must</strong> be defined, even if not used or meaningful for that project - unwanted parameter combinations are signalled - parameter values are constrained.</p> <pre><code>#if !defined(CONFIG_FOO) #error CONFIG_FOO not defined #endif #if !defined(CONFIG_BAR) #error CONFIG_BAR not defined #endif #if !defined(CONFIG_TIME) #error CONFIG_TIME not defined #endif #if !(CONFIG_FOO ^ CONFIG_BAR) #error either CONFIG_FOO or CONFIG_BAR should be se #endif #if CONFIG_TIME > 250 #error CONFIG_TIME too big #endif </code></pre> <h2><code>Makefile</code></h2> <p>By instructing the compiler to output the preprocessor macros, it is possible (with a bit of <code>sed</code> expression) to feed the <code>Makefile</code> with the same parameter values gprovided for a given project.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
