Macro Techniques using PIC16C711 Microcontroller

Lots of news before getting into this article on Macros and other ways to simplify your application development. The first is, I have finished going through the page proofs of "PC PhD" and it should be ready for going to the printers later this week. This book is about interfacing hardware to the PC along with a focus on MS-DOS software. Windows operation is also presented. The book contains four PICMicro p ...

PIC12F675 Tutorial 3 : PIC Serial Port

The 12F675 does not have a built in USART that you can use for a PIC serial port so you have to use a software USART which you can download from this page. Adding a pic serial port connection to the circuit gives you scope for much more interesting projects as you can collect data from the ADC (inputs) or comparator or external infrared receiver module etc. and transmit it to a PC. This tutorial covers crea ...

How to configure EUSART in PIC18F4550

Both, Parallel and Serial modes of communication have certain advantages and disadvantages over one another. The serial communication is a preferred option due to its ability of long distance communication with error detection capability. The microcontrollers consist of an inbuilt hardware unit known as USART (Universal Synchronous Asynchronous Reception and Transmission) to facilitate serial transfer of da ...

RS232 Communication using PIC18F4520’s USART – PIC Microcontroller Tutorial

RS232 can be used to communicate between a variety of devices. Like your MCU and a GSM module or a PC. In this tutorial we will demonstrate a link between a PIC18F4520 MCU and a standard PC. On PC we will run a terminal program like RealTerm or Hyperterminal. A terminal program is used to send and receive text data. So any text send by the MCU will be visible on Terminal Screen and Any keypress you make on ...

PIC12F675 Tutorial 5 : A Temperature data logger using PIC EEPROM

This PIC microcontroller EEPROM project saves the temperature from an LM35DZ IC to the PIC's internal long term data storage area.  The project follows on from the last project using the virtually the same hardware. It stores temperature readings internally at regular intervals until full and after this it turns on the LED. The LED is really just for showing that something is happening and in a real data lo ...

PIC12F675 Tutorial 4 : Making an LM35 temperature recorder

This page shows you how you can make an LM35 an temperature recorder by using the 12F675 PIC microcontroller as the controller and data store. It generates serial output so that you can view the results on a PC and it also calculates the temperature reading in Fahrenheit sending both to the serial port at half second intervals. The project uses the code from the previous tutorials to report the temperature ...

How to interface GPS with PIC18F4550 Microcontroller

Global Positioning System is based on satellite navigation technology. A GPS Receiver provides the accurate location of an object in terms of latitude and longitude. Accurate time calculation with respect to GMT can also be done by using GPS. For more information on different data obtained through GPS, refer GPS Receivers. Here a PIC microcontroller has been interfaced with a GPS module to extract its posit ...
