Memory and Stack usage may differ from system to system, depending on the used compiler
and its setup.
The following formula shows the way to calculate the common requirements of the driver and devices.
<total requirement> = <driver requirement> + (<number of devices> * <device requirement>)
The maximum usage of some resources is limited by adjustable parameters. If the application
and driver exceed these limits, increase the according values in your project.
