Timer Example

Introduction

This example is a timer driver test program, covering the creation, parameter configuration, interrupt callbacks, and start/stop procedures of hardware timers and software timers.

Source location: src/rtsmart/examples/peripheral/timer/test_timer.c

Example Behavior

• Hardware timer test:

  • Create instance

  • Set mode/frequency/period

  • Register callback and verify trigger count

  • Query running status and ID

  • Stop and destroy

• Software timer test:

  • oneshot and periodic modes

  • Register callback and verify trigger

  • Stop, unregister and destroy
