Runs a graphic to show how multiplexing can be used to reduce wiring to just a few cables with signals being passed 'multiplexed' on a single cable to a number of devices
Pressing the Space bar will progress you through this graphic until its end, firstly showing the multiplexed signals travelling down a single cable. Press <Space> to reveal the devices attached to this control cable. Press <Space> again to see only the device that the multiplex signal has a matching address for receiving the data intended for it
Runs a graphic to show fast & slow processing loops, with the 'watchdog' monitor making sure that no one process hogs the processor's time
Pressing the Space bar will progress you through this graphic until its end, firstly showing each sub-process running correctly and so the watchdog is reset correctly, then <Space bar>, if part of the software gets caught in a loop, the watchdog comes into play, and resets the system to the top of the program
