Microprocessor
The block in figure 3, labeled Micro Processor, includes a lot of
things, including the memory where the program and sound
files are stored and the clock that keeps time for everybody. I
lumped them together, as many times the microprocessor chip
will have built in memory and the clock is typically not con-
nected elsewhere.
Here is some of what the microprocessor is doing almost
simultaneously:
Interpreting DCC commands
Calculating motor speed and direction
Creating motor drive pulses
6: Transition Detection – looking at the change in the
DCC signal – DCC data = 111111000011.
