|
||||
* \par Purpose
|
||||
*
|
||||
* Methods and definitions for Global time tick and wait functions.
|
||||
*
|
||||
* Defines a common and simpliest use of Time Tick, to increase tickCount
|
||||
* every 1ms, the application can get this value through GetTickCount().
|
||||
*
|
||||
* \par Usage
|
||||
*
|
||||
* -# Configure the System Tick with TimeTick_Configure() when MCK changed
|
||||
* \note
|
||||
* Must be done before any invoke of GetTickCount(), Wait() or Sleep().
|
||||
* -# Uses GetTickCount to get current tick value.
|
||||
* -# Uses Wait to wait several ms.
|
||||
* -# Uses Sleep to enter wait for interrupt mode to wait several ms.
