2.1 AVR C

One of the GCC mplementations for Atmel AVR microcontrollers is Savannah NonGNU AVR Libc, which is adopted in this course. The manual can be found at http://www.nongnu.org/avr-libc/user-manual/index.html.

Two language references are suggested as:

• Savannah NonGNU AVR Libc Reference

• Language Reference on Arduino Office Website.

In our course, Language Reference on Arduino Office Website is a must read.
