The minimal-net target, as currently written, wakes up the CPU every millisecond to check for packets, and will only react in real-time to input from stdin. If you are running this on a laptop battery, your battery will quickly drain. This change allows the CPU to idle when there is literally nothing to do while still being responsive to input from stein and/or incoming packets. This fix should significantly improve performance while significantly improving power usage. Win-win. Also added `_xassert()` implementation so that the contiki- provided `assert()` macro will work properly when used on this platform.
The Contiki Operating System Contiki is an open source operating system that runs on tiny low-power microcontrollers and makes it possible to develop applications that make efficient use of the hardware while providing standardized low-power wireless communication for a range of hardware platforms. Contiki is used in numerous commercial and non-commercial systems, such as city sound monitoring, street lights, networked electrical power meters, industrial monitoring, radiation monitoring, construction site monitoring, alarm systems, remote house monitoring, and so on.
