How to connect an input shift register to a microcontroller
In order to simplify the main program, a macro can be used for the input shift register. Macro
HC597 has two arguments:
HC597 macro Var, Var1
Var variable where data from shift register input pins is transferred
Var1 loop counter
Example: HC597 data, counter
Data from the input pins of the shift register is stored in data variable. Timer/counter variable is
used as a loop counter.
