register, thus data is transformed from serial into parallel data.
An outline of the 74HC595 shift register connections is shown on the diagram below:
Connecting an output shift register to a microcontroller
Macro used in this example is found in hc595.inc file, and is called HC595.
Macro HC595 has two arguments:
HC595 macro Var, Var1
Var variable whose contents is transferred to outputs of shift register.
Var1 loop counter
Example: HC595 Data, counter
The data we want to transfer is stored in data variable, and counter variable is used as a loop
counter.
