Brief Description

This course explains in accessible, understandable detail the internal working of the AVR Atmega328p Microcontroller and its Peripherals. Most Microcontrollers work similarly so what you learn in this course can easily be used for other Microcontrollers such as Atmega8, 16, 32, 2560, PIC, MSP, NXP etc. After taking this course, you will be able to develop your own projects and products employing the AVR and similar Microcontrollers.
We will be coding and conducting lab experiments for each and every peripheral in an in-depth and step by step manner and will develop software drivers completely from scratch using the hardware registers by employing information from the datasheet and reference manual of the Microcontroller.

In many industries such as consumer appliance, automotive, and aerospace, Microcontrollers are widely used and programs for them are written in Register level using either Embedded C or C++. An understanding of Microcontroller’s internal working and peripheral programming is therefore essential for designing a successful project or product related to these industries. This will be one key takeaway from this course.

  • The average salary for Firmware developer $61,118 PA.
  • Used by top industries across various business verticals. Ex: Amazon, Intel Corporation, Microsoft, Microsemi Corporation, Samsung, LG, Bosch etc.

How is this Course Different From Other Arduino Courses?

In this course, we will be employing Arduino Hardware, which is widely available, inexpensive, and reliable, but we will not be using Arduino IDE or any of its precooked libraries, which are simplistic in design and below professional industry standards. Rather we will be designing our own superior software from scratch using the professional Atmel Studio. In the process, we will learn the use of Serial COM port for debugging the Arduino Hardware, which does not have its own debugger. This will save you the cost of buying an external debugger like the ATMEL ICE. I will cover important topics like Interrupt, which you can use to make your own scheduler including different Industry standard communication protocols.

Pros of using Arduino Hardware Board

  • Arduino Uno / Nano / Mini has 8-bit AVR AtMega328p Microcontroller and Arduino Mega has 8-bit AVR AtMega2560 with all necessary hardware required for up and running.
  • Very cheap hardware.
  • Widely available around the globe.
  • No need for separate expensive programmer hardware, internal bootloader takes care of serial programming.

Cons of using Arduino style Programming

  • Arduino IDE is not professional.
  • 3rd party libraries.
  • No Register level learning.
  • No learning about Microcontroller’s internal and on-chip peripherals like GPIO, SPI, UART, TIMER etc.
  • Not industry standard and never recommended for a product design.

My Promise
