Introduction to Microchip XC8 Compiler

image-312
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.

PIC Microcontroller Communication with I²C Bus – XC8

image-287
The I²C or Inter-Integrated Circuit is a serial communication and allows multiple devices to communicate with a micocontroller(s) over only two wires. The devices don't have to be identical as long as they support I²C protocol. In our illustration, the first device with address 1 is a digital temperature sensor, the second one is a real time clock and the third one is a serial LCD display and the bus could carry on even more devices. Communication takes place from the master (PIC) to the individual selected slave only as shown in this illustration. Configuration with PIC18F Peripheral Libraries and MPLAB Code Configurator are discussed in this article

PIC Microcontroller Communication with SPI Bus – XC8

image-283
The SPI or Serial Peripheral Interface is a synchronous serial communication and allows multiple devices to communicate with a micocontroller(s). There are many devices that support the SPI protocol and can easily communicate with a microcontroller via SPI: A/D converters, D/A converters, SD Cards, DS1306 Real Time Clocks, MAX7219 serial display drivers, 25LC256 Serial EEPROM, etc. The devices don't have to be identical as long as they support SPI protocol. In this article we are going to configure the SPI Peripheral with MPLAB Code Configurator and PIC18F Peripheral Library.

PIC Microcontroller Interrupts – XC8

image-244
Interrupts are one of the most powerful features of PIC Microcontrollers, interrupts make it possible to create applications that can respond to external stimulus in real time. An interrupt is basically an event that requires the microcontroller to stop normal program execution and then to jump to execute a program code related to the event causing the interrupt. An interrupt requires immediate attention, only once the microcontroller will finish executing the interrupt code, then it can go back to continue with the main program. The interrupt code is called Interrupt Service Routine (ISR) or Interrupt Handler. In this article we're gonna learn how to implement Interrupts using Interrupt registers and with MPLAB Code Configurator.

Interfacing ENC28J60 Ethernet Controller with PIC Microcontroller – XC8

image-2866
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. 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.
