Home Questions Tags Users Unanswered. 184f520 section uses an example to describe how to setup and write digital outputs using a PIC18F First include header file with definitions for specific PIC. This is a more explicit way of saying main is a function of nothing.
Both are defined as 8-bit numbers, with count already being assigned a value while temp is left unassigned.
PIC18F Digital Outputs – Northwestern Mechatronics Wiki
Retrieved from ” http: Working with digital inputs and outputs is fundamental to circuit design, and PIC microcontrollers add versatility to design by allowing programming and 18f450 of the logic associated with input and output pins. Digital Outputs From Mech. Ports A-D consist of eight pins each, while Port E has 81f4520 three, although some of these pins are primarily used for communication. Define variables to be used in main program. Sign up using Facebook.
Set Port D to be an output 0. For example, here are the two relevant tables: Notice main is a function of “void”. Ideally it should also be volatile as it’s used in both main and interrupt.

See header file for currently defined pin names. Actually, the code you posted doesn’t use mbut maybe that’s not all of your code, so just be aware.
