A Graphical User Interface is a man-machine interface device, in which objects to handle are drawn as icons on the screen, so the user can send controls by by a pointing device, usually a mouse or a keyboard. It is always easy and require less skills to operate a device from a visual representations of the workspace (GUI) by simply clicking a mouse or using a keyboard rather than a command line. In this article we are going to design a Graphical User Interface using Microsoft Visual C#. This software could be installed in any computer running windows operating systems. The computer will connect to the microcontroller using an RS232 serial cable. The PIC microcontroller will receive commands from the computer to control devices connected to it such as motors, LEDs etc.

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.

An automatic temperature control system has the ability to monitor and control the temperature of a specified space without human intervention. This project uses a PIC microcontroller to automatically control the temperature of an area. This area could be a small plant, a house or any place or device that require a controlled temperature like an incubator (egg) for example. The desired temperature setting is entered using a keypad. The temperature of the area is measured using an analog temperature sensor. The microcontroller reads the temperature every 10 s and compares it with the desired value. If the desired value is higher than the measured value, then the heater is turned ON, if on the other hand the measured value is higher than the desired value, then the fan is switched ON. An LCD display shows the measured temperature continuously. The project is designed using MPLAB XC8 Compiler

Microchip Libraries for Applications

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.

Digital Clock using PIC Microcontroller Interrupt – XC8

Real Time Clock and Calendar functions are very important in many projects especially in data logging devices where a real time stamp is required in each record. This clock uses Timer 1 to implement software real time and clock functions. A Real Time clock (Digital Clock) can be made easily by using Timer 1 of a PIC Microcontroller. The Timer1 module exists in most of the series of PIC, this module can be used to easily implement a real-time clock. Instead of an external real-time clock device like a DS1307, an inexpensive 32.768 kHz watch crystal and two 33 pF capacitors are used to complete the circuit. In this application, Timer 1 is clocked by an external crystal (32.768 kHz) connected across RC0 (T1OSO) and RC1 (T1OSI).

Real Time Clock and Calendar functions are very important in many projects especially in data logging devices where a real time stamp is required in each record. This clock uses the DS1307 which is a low power serial real time clock/calender with full binary coded decimal (BCD) clock/calendar plus 56 bytes of Non Volatile Static RAM. This chip provides year, month, date, hour, minute and second information. The end date of months is automatically adjusted for months fewer than 31 days including leap year compensation up to year 2100.

Digital Barometer using PIC Microcontroller and MPX4115A Pressure Sensor – XC8

The MPX4115A is an atmospheric pressure sensor powered by 5V and delivers and output from ~0.25V to ~4.75V based on the pressure detected at room temperature (25°C). The device provides a linear output based on pressure. It can measure pressures between 15kPa and 115kPa. Note that 1 atmosphere of pressure at sea level is equal to 101,325 Pa or 101 kPa. This sensor is ideal for microcontroller based barometer, altimeter, data logger or weather station applications. In this article, we're gonna create a simple Digital Barometer using MPLAB XC8 compiler.

Digital Thermometer using PIC Microcontroller and LM35 Temperature Sensor – XC8

Temperature sensors are very important in many projects especially in temperature logging devices and alarms. In this article we are going to design a digital thermometer using MPLAB XC8 compiler. This digital thermometer is built around the LM35 which is a precision integrated-circuit temperature sensor whose output voltage is linearly proportional to the Celsius (Centigrade) temperature. Its output changes by 10 mV per °C so there is no need for calibration. It can measure a wide range of temperature from −55 to +150°C

For many hobbyists and students interested in programming PIC Microcontrollers, the high cost of a programmer can really be a huge obstacle. The programmer described in this article is very easy and cheap to build. It can cost you less than R 100 ($10) to build it and all the software used to program the PIC luckily are also free. You can use MPLAB X IDE with XC8, XC16 or XC32 compilers from Microchip Technology Inc that can be used to write and debug code for a PIC Microcontroller. You can download a free copy of MPLAB® X IDE and XC8 Compiler from Microchip website. They are also other compilers that you can use depending on your preference, like Mikroelekronika compilers where you can download a free 2Kb limited demo compiler on their website.
