This is a Getting Started with MPLAB X IDE and XC8 compiler tutorial. MPLAB® X IDE is the new Microchip IDE and it runs on a PC with Windows®, Mac OS® or Linux® to develop applications for PIC microcontrollers and replaces all MPLAB® C and HI-TECH compilers. XC8 is the new C compiler for PIC10, PIC12, PIC14, PIC16 and PIC18 microcontrollers. Learn how to start a new project with MPLAB X IDE, configure your PIC fuses and oscillator, write a simple Blink LED code and simulate the code with Proteus.
The 7-segment display is the earliest type of an electronic display that uses 7 LEDs bars arranged in a way that can be used show the numbers 0 - 9. (actually 8 segments if you count the decimal point, but the generic name adopted is 7-segment display.) These devices are commonly used in digital clocks, electronic meters, counters, signalling, and other equipment for displaying numeric only data. It is not different from an LED in terms of interfacing, by turning the appropriate segments ON and OFF we can display easily the numbers 0 to 9 and optionally the decimal point (DP). The segments of the displays are normally referred to by letters ‘a’ to ‘g’. In this article we are going to learn how to multiplex two or more 7-Segment displays to be able to display numbers higher than 9. MPLAB XC8 compiler is used in this tutorial.
Many computers especially portable ones do not have a serial port (COM Port) anymore. When a connection to a Personal Computer (PC) is required, a USB is the choice. The Universal Serial Bus (USB) is the widely used interface in electronic consumer products today. Most of electronic devices have at least one USB port on them, this include PCs, cameras, GPS devices, printers and so on. Some PIC18 microcontrollers support USB interface directly. 16bits (PIC24) and 32-bits (PIC32) pic microcontrollers have also an embedded USB interface. In this article we will learn how a communication between a host PC and a microcontroller can be achieved with a USB bus.
Ethernet is the leading wired standard for networking as it enables to connect a very large number of computers, microcontrollers and other computer-based equipment to one another. With just a network switch, many different devices can easily communicate with one another with Ethernet, allowing different devices and equipment to be accessed remotely and this also provides a cost-effective and reliable means of remote control and monitoring, home automation, Internet of Things applications and many more. If you are using a microcontroller which does not have an integrated Ethernet peripheral, Microchip offers a serial Ethernet chip that can easily be used by any microcontroller with an SPI interface to provide Ethernet capability to the application. many compilers offer peripheral libraries to get you started in minutes.
Microchip Libraries for Applications (MLA) is a collection of Microchip firmware libraries, drivers, demo projects, documentation and utilities for different type of applications including USB, Graphic displays, File I/O (Memory cards), TCP IP, Smartphone and many more. Not all firmware libraries and demo projects from Microchip are distributed in this package; rather, this package includes a few specific libraries that tend to be used together. By distributing libraries that are used often together, Microchip can provide example projects that integrate the use of multiple libraries.
A memory card (also called a flash memory card) is a solid-state electronic data storage device used for storing digital information. They are commonly used in many electronic devices, including digital cameras, mobile phones, laptop computers, MP3 players and also in many applications where a large amount of data has to be stored either once or continuously like in data loggers. Memory cards are small, re-writable and are able to retain data without power. In this article we will learn how to interface an SD Card with a PIC Microcontroller with SPI bus to write and read to/from an SD card with MPLAB XC8 and MPLAB Code Configurator.
The MPLAB® Code Configurator (MCC) is a user friendly Graphical User Interface (GUI) plug-in tool for MPLAB® X IDE which generates easy to understand C code that is inserted into an MPLAB® X project, based on the settings peripherals configurations and selections made in the Graphical User Interface (GUI). The generated code can be used in any application program. When starting out with a new project using Microchip 8-bit microcontrollers, setup of the configuration and all the peripherals can be time consuming, especially for new projects. The MPLAB® Code Configurator simplifies this down to a series of simple graphical selections from the menus within the MCC.

With just a network switch, many different devices can easily communicate with one another with Ethernet, allowing different devices and equipment to be accessed remotely and this also provides a cost-effective and reliable means of remote control and monitoring. For microcontrollers which don't have an integrated Ethernet peripheral, Microchip offers a serial Ethernet chip that can easily be used by any microcontroller with an SPI interface to provide Ethernet capability to the application. The ENC28J60 is a popular 28-pin serial Ethernet chip, 10BASE-T stand alone Ethernet Controller with SPI interface, on board MAC & PHY, 8 Kbytes of Buffer RAM and an SPI serial interface. In this article we will learn how to use the ENC28J60 Ethernet controller with Microchip TCP/IP Lite Stack and MPLAB Code Configurator.
