Digital electronics 2

The repository contains AVR lab exercises for bachelor course Digital Electronics 2 at Brno University of Technology, Czechia. Arduino Uno and some shields are used as the main programming platform.

Exercises

1. Git version-control system, AVR tools
2. Control of GPIO, LED, push button
3. User library for GPIO control
4. Interrupts, timers
5. Display devices, 7-segment display
6. Display devices, LCD display
7. ADC and UART serial communication
8. I2C/TWI serial communication
9. C project: General instructions
10. (Self-study) Combining C and assembly language

List of examples

• Basic C template, blink a LED
• Project documentation with Doxygen
• C libraries
