1  Using Arduino / Programming Questions / Reading a byte from the digital pins on: May 28, 2011, 12:12:56 am
Hello everybody,
I am new user of Arduino and I am learning the difference between the old microprocessor 8080 I have used many years ago and this new PIC. In my brain I remember a simple instruction which loads in the ALU (or in the RAM) one byte from the input port and then you can assign this byte as variable. In Arduino I have not found similar instruction, instead it uses a string, sent by serial line. Where is the trick by loading a parallel byte from input digital pins in the ALU?
Thanks in advance, Godifredo
