Embedded IR Remote Control with NEC Protocol

Control your Embedded Device using IR Remote Controls

9+ hours | Complete Source Code Included

Hello, Welcome to the Embedded IR Remote Control with NEC Protocol course.

This course teaches you how develop bare-metal drivers and libraries to enable you to control your embedded device using IR remote controls. Essentially, you should be able to control your embedded device using any remote control you have lying around at home.

If this is a skill you want to add to your embedded skillset, then take a look at our Embedded IR Remote Control with NEC Protocol course.

So with that understood, let me tell you…

Exactly What You’re Getting

This course can be divided into 4 major sections.

First Section

The first section is theoretical. In this section we learn about IR remote control modulation and encoding theory, and also the structure and features of the NEC protocol. Over here we shall deal l with topics such as

Amplitude Shift Keying (ASK) modulation vs Frequency Shift Keying Modulation (FSK)
Pulse Position Encoding
Pulse Width Encoding
Pulse Distancing Encoding
Frame Format of the NEC protocol

Second Section

In the second section we shall develop all the divers to help us debug and implement some realword applications once we have developed all modules of the system. Over here we shall develop :

A Timebase to help us generate precise delays
An ADC driver to help us sample sensor data when a particular key is pressed on the IR Remote control
A UART driver to help us to print out debug information
A GPIO driver to turn on the light when a particular key is pressed on the IR Remote control

Third Section

In the third section we shall develop the drivers and library required for interfacing the IR receiver to our microcontroller and decoding the received pulses. Over here we shall develop :

An external interrupt driver for detecting edge changes from our IR receiver pin
A timer driver for measuring pulse length

An then we shall develop the library for fully decoding the pulses received by the IR receiver

Last Section

Once all the system drivers and library are fully developed, we then develop some real-world applications.

Sending We shall develop firmware application for turning on the light based on the key pressed on the remote control
We shall develop firmware application for sampling and displaying sensor data based on the key pressed
We shall develop firmware application for displaying the time based on the key pressed.
We shall develop firmware application for displaying the key pressed on any remote control we have at home, the reason this will work is because most remote controls are based on the NEC protocol.

As always, no copy/paste. We write each line code from scratch.

Some of you may have taken some of my embedded systems courses from other online platforms.

This is my private channel.

I have been writing embedded firmware for years, I have built embedded devices like consumer products and robotic arms.

Till date I have

trained over 75,000 students in embedded

firmware development online till date

...including third year undergraduate university students in-person.

If you have taken any of my courses before you will know I start from the absolute basics, I do not assume that the student has any prior knowledge of the topic under discussion. You will also know that by the end of the course you understand the functions of every register used in developing the particular firmware or driver.

This method is the same for all of my published embedded systems courses.

Our courses have been reviewed by 1000+ students
