Getting Started with C Programming for the ATMEL AVR Microcontrollers
This tutorial provides information on the tool and the basic steps for programming the Atmel AVR microcontrollers using C. It is aimed at people who are new to this family of microcontrollers. The Atmel STK500 development board and the ATmega16 chip are used in this tutorial; however, it is easy to adopt the information given here for other AVR chips.
Summary
This tutorial introduces C programming for Atmel AVR microcontrollers using the STK500 development board and the ATmega16. It walks readers through toolchain setup, basic peripheral programming (GPIO, timers, ADC), compiling and flashing firmware, and adapting examples to other AVR chips.
Key Takeaways
- Set up the AVR-GCC toolchain and STK500 hardware to build and flash C firmware.
- Write and structure C code for AVR microcontrollers to control GPIO, timers, and ADC.
- Configure and use interrupts and simple peripheral drivers for responsive embedded behavior.
- Compile and upload firmware using Makefiles and AVRDUDE, and perform basic on-target testing.
- Adapt ATmega16 examples and register-level code patterns to other AVR devices.
Who Should Read This
Early-career embedded engineers, students, and hobbyists with basic C knowledge who want a practical, hands-on introduction to programming Atmel AVR microcontrollers (STK500/ATmega16).
