Hi guys!
Although I am spending my whole holiday in my garden in the sun,
sometimes I am looking into the Internet to see what´s happening.
Okay, here is a short discription of the FCU board:
Three MCUs on the board (MCU=Microcontroller Unit:
MCU1 multiplexes the 7-seg-Displays and the pushbuttons
MCU2 is the Bus-Interface
MCU3 scans the ALPS-Incremental switches and debounces the
switches.
Q: Why three MCUs?
A: Speed, reliability, no display flickering during data transfer.
The whole thing is powered with 12 Volt like the whole cockpit
There is a switchmode powersupply on the FCU board which makes
the +5 Volts out of the 12 Volts with low power dissipation/low heat.
Well, that´s it.
Now I go back into my garden to enjoy the sun.
Best regards, have fun!
