Long Description:
Learning Embedded System Programming can be a challenge. Since it's a relatively complex field, there's no actual gold standard yet for how things are practiced, or taught, which can frustrate people who are just trying to learn new things and couldn't connect the dots.
This is the motivation behind creating this course to help engineers and students learn different aspects of embedded systems by providing high-quality advanced lectures at a relatively low price.
Master Behind the Scene working;
created this course because I believe your time is precious, and you shouldn't have to hunt around to get a practical foundation In Embedded System Programming. In this course, you will learn to write your peripheral driver for most commonly used peripherals such as GPIOs, I2C, SPI, USART, etc., and the exciting thing is that you will learn everything from scratch.
No 3rd party libraries!
No blind coding!
Write your driver APIs by dealing with the peripheral registers of the MCU!
Code and Implement APIs from scratch, diving into the datasheet and reference manual of the MCU. I will thoroughly explain how to extract the maximum information from datasheets, Technical Reference manuals to configure and handle peripherals. These techniques you can go and apply to any MCUs you have at your hand.
In this course, I will walk you through step-by-step procedures on configuring various Peripherals like GPIOs, SPI, USART, I2C by taking you into the reference manual and datasheet. We will develop a fully working driver code, interrupt handlers, sample application everything from scratch to understand the big picture.
In each lecture, I assure you that you will learn something new to use in your work or projects. You'll find yourself handling these peripherals with much more clarity. You will be able to speculate and debug the problem quickly. I'll show you tricks and tips to debug the most common issues using debugging tools such as logic analyzers.
This is not the Arduino style of programming:
I believe Arduino is for quick prototyping of projects/products but not for mastering the working of micro-controllers and their peripherals. Unlike Arduino programming, where you develop a quick solution and prototyping of products using third-party libraries, this course is entirely different. In this course, no 3rd party libraries are used. Everything we will code by referring to the technical reference manual of the MCU and will create our own library. The Power of this approach is that you can quickly speculate problems and debug like a pro when things go wrong in your project due to bugs. If one thing me and my students are good at is "debugging,." To achieve good debugging skills, it's essential to code by understanding how things work behind the scene but not by blindly using some third-party libraries, and that's the biggest TAKE away from this course.
The course is designed and explained so that it is generic across any microcontroller. The code we develop can be used as templates to quickly build a peripheral driver for your MCUs on-chip peripherals.
Software/Hardware used:
In this course, the code is developed so that it can be ported to any MCU you have at your hand. If you need any help porting these codes to different MCUs, you can always reach out to me! The course is strictly not bound to any 1 type of MCU. So, if you already have any Development board that runs with an ARM-Cortex M3/M4 processor, I recommend you continue using it. But if you don't have any development boards, then check out the below Development boards.
1. STM32F407xx based Discovery board ( This is the board used in this course)
MCU Vendor: STMicroelectronics
IDE: STM32CUBEIDE (Free)
My promise:
I am confident that this course will save you many hours of studying/experimenting/googling time to learn about MCU programming. I will personally answer your questions about this material, either privately or in a group discussion. If you are not satisfied, for any reason, you can get a full refund from Udemy within 30 days. No questions asked. But I am confident you won't need to. I stand behind this course 100% and am committed to helping you.

It's interesting but relying too much on the IDE functionalities. I would at least include a generic way to do it with like gdb integrations. Other then that, it does give some more insights in how to debug in embedded.

Excellent course for understanding Microcontrollers! I really enjoyed learning through this MCU1 course. The concepts were explained in a clear and practical way, which made it much easier to understand how the microcontroller works internally and how different peripherals interact with it. I especially liked the focus on GPIO, RCC, interrupts, NVIC, vector tables, SPI, debugging, memory architecture, and register-level programming. The practical approach helped me connect the theoretical concepts with actual MCU programming. The course gave me a much better understanding of microcontrollers and increased my interest in embedded systems. I genuinely enjoyed the learning process and would definitely recommend this course to anyone who wants to build a strong foundation in microcontrollers. Thank you for creating such a valuable course!

Very complete course. I'm very happy with the topics covered. Howerver, I must warn this is not for the absolute beginner. Some exposure to software and hardware might be necessary to get the most out of the course.
By Jesus Pacheco on 7/21/2026
I learn a lot with this course. I think bare metal driver development must be the first step when we decide to go for embedded development. This was a foundational course for me. I really enjoyed this course and I gained a lot of experience. I actually bought a nucleo-F411RE board to practice with it. Thanks!
By Mohamed Hassan on 5/16/2026
This course is good course on driver development. It builds really from the basics and gives you a deep understanding on the driver files and how it is used to run the program. It can be slightly overwhelming for beginners but with consistent and further research on your own on some topics can give you more clarity When I started this course I had no prior idea or knowledge about how MCU works or what embedded system is. From the beginning to the mid section when the lecturer writes code you can't see the big picture and feels lost, like I didn't understand what I am coding just blindly following during the ADDRESS initialization of the peripherals. But when started to code and write for different peripherals I started to understand slowly one by one.

Man, this course is going to save a lot of people who are struggling to find a role in embedded systems especially as a firmware/software engineer. Worth every penny spent on this, wish I discovered this course a lot earlier. Also not to mention, the other courses from you as well are equally great! Kudos to you for teaching us almost everything we need to know about embedded systems/firmware engineering. Thanks a ton!
By Sai Visruth on 4/20/2026
I am going through this course, it focuses on explaining the basics of microcontroller. I would reccommend this course to those who wish to learn the basics and have a strong foundation on embedded electronics
By Adam Markovich on 4/18/2026
Good course for getting into STM32 ARM Cortex development. There is quite a bit of important material covered here. I really like how "hands on" this series of lectures is. Get an Arduino UNO , logic analyzer and breadboard along with the mentioned RTC module and LCD screen for maximum benefit.
By Anonymized User on 4/8/2026
This was such an incredible course. I'm really happy with my results and the knowledge I gained thanks to it. Now I'm working with the HAL libraries, and I've quickly become familiar with them thanks to the strong foundation obtained in this course. Highly recommended
By Awdhesh on 1/11/2026
This is best course for deep understanding of microcontroller driver development on udemy. However, this course lacks one area: ADC, DAC, and USB driver development. I'd like to request the instructor to either include this in the course or create a separate course for it.
By Javi Casas on 11/15/2020
Very useful and interesting course. You will program GPIO, SPI, I2C and USART peripherals drivers from scratch and learn how they work.
It doesn't dig in peripheral's advanced modes (that would have been great and is the only reason why it doesn't get 5 stars) but you get the knowledge to study those advanced features by yourself.
If you like microcontrollers and want to understand these peripherals, don't doubt it, you have to attend to this course.
Enjoy it!
By Arthur M on 11/15/2020
This was my 3rd course from Kiran/Fastbit, after the absolute beginners and ARM Cortex course (both of which I recommend, even as an experienced software developer). This instructor is great, and this is another great course . You'll write a lot of code, which is the strength of this series of courses. I'd probably say that if you are an absolute beginner to embedded systems programming, do the embedded C course first. This one assumes a basic level of knowledge beforehand. It's a long one too, I don't think I could go straight to MCU2 after this, personally I'll take something else in between to keep things fresh.
