microcontroller - Difference between reading PORT and PIN

WebMar 14, 2013 · This circuit works such that if you set a pin to 0, the output will be pulled to ground and can only be read as 0 because externally you can't pull it high. If you want to allow both levels to be input, you have to set the pin to 1. In this case you can: leave output floating if you have internal pullups (reads as 1) pull output to Vcc (reads as 1) WebInput port reading allows you to read file names or data from an optional input port.
