How do you read an entire port (8 bits) and store that value? For example, I want to read port A since I am using a Mega and I think I am using port A in parallel so pins 22-29, 22 being the LSB. I cannot find anything on google! Has google actually failed me? Or have I failed myself :frowning:

How to read a port?!

I looked on their port manipulation page and from what I understand, you have to make the port an input:

DDRA = 0;

and then read the port

value = PORTA

Am I right?
