Arduino under the Hood - AVR for Professionals

About Arduino under the Hood - AVR for Professionals

As one of the most

extensive courses available

: we will look at _everything_ and more under the hood of Arduino. At its core, the ATmega328P MCU integrates many features that are not exposed through the Arduino library. While learning how the periphery works, the student writes code, exhibiting

high performance

at

low power consumption

. Embedded systems deployed in the field and powered by small batteries can run and collect data for years. The enormous advantage of the AVR platform is that many concepts introduced in this course also apply to other MCUs. Therefore, an entire portfolio of MCUs, ranging from the small ATtiny to the larger ATmega series, becomes accessible. The ATmega328P used in this course is just an example and the gained knowledge is applicable to many embedded systems not limited to the Arduino platform. This is motivated by

practical sessions

and

exercises

in which real-world problems are to be solved. In case questions during implementation arise, the student can peek at hints and tips and if nothing works, also at the

solutions

with plenty of comments in the source code. This course provides

handmade captions

in English covering the following topics, which focus on the

practical aspects

and what a concept can be used for. In addition, the course does not follow a particular outline and the topics can be taken in any order based on the interest and needs. The covered topics include: 1. GNU Compiler Collection and what happens in every Step and why 2. A brief introduction to C and Pointers 3. Moving from the Arduino library to AVR: Less Luxury, faster Execution, fewer Resources 4. How to compile with Makefiles? Targets, Rules, and Shortcuts 5. Easy Mistakes in C and how to avoid them 1. Attack Vectors 6. Peripheries: 1. Timers, Counters, and Pulse Width Modulation 2. Interrupts 7. Communication Protocols 1. UART/USART 2. I2C/TWI 3. SPI 4. DHT and 1-Wire 5. USI 6.

How to mimic other, formerly incompatible, and unsupported Protocols?

8. Analog-Digital Converter 1. How does it work? 2.

Bonus Chapter: Parallel Task Execution

After completing this course, the successful student will have the experience not only to evaluate existing software but also create implementations that are highly optimized to be deployed on small microcontrollers to squeeze out every quantum of performance and battery life.
