00004     Some tips and tricks:
00005     -   To use the built-in LED:
00006             DigitalOut led1(LED1);
00007             ...
00008             led1 = 1;
00009     -   To delay the call of a function:
00010             Timeout someTimeout;
00011             ...
00012             someTimeout.attach(callback(&someFunction), 0.5) with 0.5 as 500 milliseconds
00013     -   The variables that are used in interrupt callbacks have to be volatile, 
00014         because these variables can change at any time. Therefore, the compiler is not 
00015         going to make optimisations.
