Timers, periodic or not, can now be restarted thanks to esp_timer_restart function.
This is done atomically, which can be used to feed a periodic timer, or simply change the period.
ESP32-C2 has a single group timer, thus it will use it for the interrupt watchdog,
which is more critical than the task watchdog. The latter is implement in
software thanks to the `esp_timer`component.
- For ESP32 | SPIRAM_MALLOC_ALWAYSINTERNAL=0
- Forced `esp_timer_create` to allocate resource from the internal memory
- WiFi/BT coexistence will sometimes arm/disarm timers from an ISR
where flash may be disabled. This can lead to a cache-based
exception as the timer instance will be located in the PSRAM.
This commit updates the visibility of various header files and cleans up
some unnecessary inclusions. Also, this commit removes certain header
include paths which were maintained for backward compatibility.
esp_timer:
Control flow issues (DEADCODE)
Execution cannot reach this statement: "break;".
protocomm_httpd:
(UNUSED_VALUE)
Assigning value from "cookie_session_id" to "cur_cookie_session_id" here, but that stored value is overwritten before it can be used.
esp_flash_api:
Null pointer dereferences (REVERSE_INULL)
Null-checking "chip" suggests that it may be null, but it has already been dereferenced on all paths leading to the check.
Added the following new APIs to the esp_timer module:
- esp_timer_get_period(): Returns the period of a timer in microseconds.
- esp_timer_get_expiry_time(): Returns the timeout value of a one-shot timer in microseconds.

- Added an option to skip unhandled events for periodic timers. Useful for light sleep.
- Added doc about this case
- Added Test a latency between a call of callback and real event (14-16us). and UT to check skip_unhandled_events.
- Fixed for esp_timer_dump() if name of timer is NULL
- Refactored timer_process_alarm()
- Added the delete function after using in UTs
* Target components pull in xtensa component directly
* Use CPU HAL where applicable
* Remove unnecessary xtensa headers
* Compilation changes necessary to support non-xtensa gcc types (ie int32_t/uint32_t is no
longer signed/unsigned int).
Changes come from internal branch commit a6723fc
- Introduce system time function and concept of system time provider.
esp_timer is system time provider when present.
- Set the reference point for system time, g_startup_time.
- Use the system time functions in newlib instead of calling esp_timer
functions directly
