Controlling a PIC Microcontroller from a PC Graphical User Interface (GUI)

image-2345
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.

Digital Thermometer using Arduino and LM35 Temperature Sensor

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 Arduino Uno. 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

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.

Automatic Temperature Control System using PIC Microcontroller – XC8

image-114
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

image-1385
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 and the DS1307 Real Time Clock – MikroC

image-128
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. In this article we are going to design a digital clock using the DS1307 RTC with MikroC Pro for PIC compiler
