Overview
The Sequencer is a utility that helps schedule tasks in systems
without an OS.
Description and Usage
Description:
The Sequencer utility has been designed as a simple alternative to
using a real-time operating system for less complex application cases.
However, it does not cover all the services provided by an operating
system.
The main features of Sequencer are:
- Task creation: Register a task so the Sequencer can call it.
- Task enable: Mark a task runnable from another task or an
interrupt.
- Task pause/resume: Temporarily stop or resume a task from the
scheduler’s viewpoint.
- Idle task: Optional hook called when no task is runnable.
Usage:
The start-up sequence can be split into five steps:
Step 1: Sequencer
initialization
Initialize the Sequencer once with SEQ_Init() after
basic hardware setup and before scheduling any tasks
Step 2: Task Definitions
Define tasks as short non-preemptive functions that return quickly,
using either single-action tasks (one-shot actions) or state-machine
tasks (advance one step per call with internal state).
Step 3: Registering Tasks
Register each task with a task ID bit and its callback function using
SEQ_RegTask().
Step 4: Enabling Task
Execution
To schedule work, set the task bit with a priority index (0 =
highest) using SEQ_SetTask().
Step 5: Launching the
Sequencer
Call SEQ_Run() inside the infinite loop to let the
Sequencer process all pending tasks.
