Detailed Description

Class gathering access to connected hardware.

HWAccess manages every connected hardware and acquires data form master and slaves. It is also responsible for synchronisation between connected devices. It can hold multiple types of hardware objects, derived from HWThread, whereby only ONE master is allowed coincident.

Attention:

Inappropriate downsamlpling used now!

Todo:

Eliminate the master/slave ratio principle!
