Description

A port of freeRTOS to flexibly use Timer0, Timer1 or Timer3 (1284p or 2560) on AVR ATmega devices commonly found in Arduino, but also in Freetronics and Pololu products.

Integrated Timer2 RTC system_time off 32.768kHz crystal for 1284p Goldilocks or other RTC equipped boards. Also works as approximate RTC off other timers using 16MHz and other crystals.

The Goldilocks 1284p is available from Freetronics.
