Read Modify Write Problem with Mid-Range PIC Microcontrollers

Ligo George — Mon, 16 Jun 2014 09:56:16 +0000

RMW Problem with PIC 16F Family Microchip’s mid-range PIC Microcontrollers use a sequence of operations : Read, Modify and Write to change output state of a pin. In certain circumstances RMW operations might cause unexpected behavior of outputs. You might have already experienced this issue and struggled with it as you can’t find exact reason […]

Generating PWM with PIC Microcontroller using Hi-Tech C

Ligo George — Wed, 23 Oct 2013 02:18:31 +0000

PWM (Pulse Width Modulation) is a powerful technique used to generate analog voltage using digital signals. It has a wide variety of applications such as controlling average power delivered to a load, generating analog voltage level, sine wave generation and DC Motor speed control. PWM signals are ON-OFF signals (hence the name Pulse) whose ON duration […]

Using UART of PIC Microcontroller – Hi Tech C

Ligo George — Wed, 07 Aug 2013 18:30:25 +0000

UART stands for Universal Asynchronous Receiver / Transmitter. It is a serial communication interface which uses two lines for sending (TX) and receiving (RX) data. As its name indicates it is an asynchronous communication interface, which means it doesn’t need to send clock along with it as in synchronous communications. UART is the communication standard […]

Interfacing LCD with PIC Microcontroller – Hi Tech C

Ligo George — Mon, 22 Jul 2013 17:05:56 +0000

16×2 Character LCD is a very basic LCD module which is commonly used in electronics projects and products. It contains 2 rows that can display 16 characters. Each character is displayed using 5×8 or 5×10 dot matrix. It can be easily interfaced with a microcontroller. In this tutorial we will see how to write data […]

Using ADC Module of PIC Microcontroller – Hi Tech C

Ligo George — Wed, 10 Jul 2013 02:54:06 +0000

Analog to Digital Converter (ADC) is a device that converts an analog quantity (continuous voltage) to discrete digital values. This is very useful when we want to do some processing on physical quantities, which are normally analog in nature. Most of the PIC Microcontrollers have built in ADC Module. Here we are using PIC 16F877A […]

Using Push Button Switch with PIC Microcontroller

Ligo George — Sun, 30 Jun 2013 15:58:03 +0000

I hope that you have already read the first tutorial of Hi Tech C, LED Blinking using PIC Microcontroller. In that tutorial we blink LEDs connected to PORTB by writing to entire PORT and TRIS registers. In some cases we may want to set or reset individual bits of these registers. For that we can […]

Blinking LED using PIC Microcontroller with Hi-Tech C

Debarati — Tue, 11 Jun 2013 04:08:46 +0000

A lot of you may heard about microcontrollers and its applications. Well it is a bit difficult to start learning microcontrollers. And the guides and tutorials also do not start from zero level which makes learning far more difficult than anticipated. I have tried to start from zero level in here also. All you need […]
