Here’s an overview of what you’re getting in this advanced level course...

Developing bare-metal DMA Drivers

This course completely demystifies the Direct Memory Access (DMA) peripheral. Over 50% of the course is spent on this topic, so that by the end of this course you would have mastered the DMA peripheral.

We shall thoroughly look at developing the following bare-metal DMA drivers.

- Bare-Metal DMA Memory-to-Memory Transfer Driver

- Bare-Metal ADC DMA Regular Conversion Driver

- Bare-Metal ADC DMA Timer Triggered Conversion Driver

- Bare-Metal UART RX/TX DMA Driver

- Bare-Metal SPI RX/TX DMA Driver

- Bare-Metal I2C RX/TX DMA Driver

- Bare-Metal PWM DMA Driver

Developing bare-metal RTC Drivers

The Realtime Clock (RTC) peripheral is another advanced peripheral demystified in this course. We shall study the theory of realtime clocks, take a look at the capabilies of the realtime clock on our microcontroller and then develop the following drivers for the realtime clock.

- Bare-Metal RTC Calendar Driver

- Bare-Metal RTC Alarm Driver

- Bare-Metal RTC Timestamp Driver

- Bare-Metal RTC Tamper Detection Driver

Developing bare-metal Watchdog Timer Drivers

Watchdog Timers are an essential component of any robust embedded device. In my opinion, no embedded device should be released onto the market without the implementation of an Independent Watchdog Timer (IWDG). You will understand why I hold this opinion in the course.

In this course we shall develop the following Watchdog Timer drivers:

- Bare-Metal Independent Watchdog (IWDG) Timer Driver

- Bare-Metal Windowed Watchdog (WWDG) Timer Driver

Working with Standby Mode and Wakeup

Knowing how to put your embedded devics into Low-power mode and coming out of it will greatly improve your ability to developer power efficient embedded solutions. This course will teach you how to put your device into Standby mode and come out of it using different methods.

Specifically, we shall develop the following drivers:

- Bare-Metal Standby Mode and Wakeup Pin Driver

- Bare-Metal Standby Mode and RTC Wakeup Timer Driver

The Art of Debugging

Knowing how to properly debug your firmware will save you lots of time and money, and may even prolong your life because of the level of frustration and stress you will avoid.

In this course you shall grasp the theoretical aspects of debugging, understand the various types of debugging such functional debugging and performance debugging, and learn the various tools and methods used in different scenarios.

Some of the techniques we you will master include:

- Methods of identifying the cause of HardFault

- Catching anomalous results

- Measuring execution time of an algorithm using a Timer

- Measuring execution time of an algorithm using a Logic Analyzer

- Working with arrays dumps

- Debugging techniques for Timers

A little about me : Israel Ninsaw Gbati

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
