Timer Driver Sample Application

Description

The Timer Driver sample application validates timer APIs and both timer modes introduced in the updated naming model:

  • TIMER_MODE_ONE_SHOT

  • TIMER_MODE_PERIODIC

The app executes functional testcases and prints pass/fail status on the logger console.

Implemented testcases:

  • TMR-FN-01: Validate blocking APIs (timer_wait_us, timer_wait_ticks).

  • TMR-FN-02: Validate one-shot mode (timer_start_us(..., TIMER_MODE_ONE_SHOT)) callback behavior.

  • TMR-FN-03: Validate periodic mode (timer_start_us(..., TIMER_MODE_PERIODIC)) and stop behavior.

  • TMR-FN-04: Validate system counter progression and remaining-time query APIs (timer_get_system_count, timer_get_remaining_ticks, timer_get_remaining_us).

  • TMR-FN-05: Validate cancellation of a running one-shot timer via timer_stop.

  • TMR-FN-06: Optional slowclk mode validation (one-shot + periodic). If slowclk timers are unavailable on the target, this testcase is reported as skipped.

Supported Boards

  • SL2610_RDK

  • SR110_RDK

Defconfigs

  • sl2610_rdk_cm52_timer_sample_app_all_defconfig

  • sr110_rdk_cm55_timer_sample_app_all_defconfig

Build and Flash (CLI)

  1. Build from the application directory:

cd <sdk-root>/examples/driver_examples/timer_sample_app
export SRSDK_DIR=<sdk-root>
make sl2610_rdk_cm52_timer_sample_app_all_defconfig BUILD=SRSDK

SR110 build example:

make sr110_rdk_cm55_timer_sample_app_all_defconfig BUILD=SRSDK

  1. Rebuild only the app (after SDK package is available):

make build

  1. Generate image and flash using the standard SL2610 flow documented here:

Expected Log Summary

On successful run, logs show the configured testcase flow for the selected board. For example:

=== [TMR-FN-01] Blocking Wait API Test ===
...
=== [TMR-FN-01] Blocking Wait API Test PASSED ===

Notes

  • Test timing can be tuned via Kconfig options in kconfig.

  • The sample avoids using blocking timer waits while periodic mode is active, to prevent self-contention in constrained timer-instance configurations.
