STM32 contiki porting level 3 (medium): timer Chinese Version

In view of their low level of English, here, I will translate the previous article on contiki timer into Chinese, so that I can learn more conveniently. There are a lot of things in this article that are not very smooth.

 

Timers

The Contiki system provides a clock library for applications and the system itself. The clock Library provides functions such as checking time exceeds, awakening the system from low-power mode to scheduled time, and real-time task scheduling. The clock is also used for applications to allow the system to work with others, or for a period of time before the recovery is executed into the low power consumption mode.
