Install Temperature Threshold Callback
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
{IDF_TARGET_NAME} supports automatically triggering to monitor the temperature value continuously. When temperature value reaches a given threshold, an interrupt will happen. Thus users can install their own interrupt callback functions to do what they want. (e.g. alarm, restart, etc.). Following information indicates how to prepare a threshold callback.
|
||||
|
||||
- :cpp:member:`temperature_sensor_event_callbacks_t::on_threshold`. As this function is called within the ISR context, you must ensure that the function does not attempt to block (e.g., by making sure that only FreeRTOS APIs with ``ISR`` suffix are called from within the function, etc.). The function prototype is declared in :cpp:type:`temperature_thres_cb_t`.
|
||||
|
||||
You can save your own context to :cpp:func:`temperature_sensor_register_callbacks` as well, via the parameter ``user_arg``. The user data will be directly passed to the callback function.
|
||||
|
||||
.. code:: c
|
||||
|
||||
IRAM_ATTR static bool temp_sensor_monitor_cbs(temperature_sensor_handle_t tsens, const temperature_sensor_threshold_event_data_t *edata, void *user_data)
|
||||
{
|
||||
ESP_DRAM_LOGI("tsens", "Temperature value is higher or lower than threshold, value is %d\n...\n\n", edata->celsius_value);
|
||||
return false;
|
||||
}
|
||||
|
||||
// Callback configurations
|
||||
temperature_sensor_abs_threshold_config_t threshold_cfg = {
|
||||
.high_threshold = 50,
|
||||
.low_threshold = -10,
|
||||
};
|
||||
// Set absolute value monitor threshold.
|
||||
temperature_sensor_set_absolute_threshold(temp_sensor, &threshold_cfg);
|
||||
// Register interrupt callback
|
||||
temperature_sensor_event_callbacks_t cbs = {
|
||||
.on_threshold = temp_sensor_monitor_cbs,
|
||||
};
|
||||
// Install temperature callback.
|
||||
temperature_sensor_register_callbacks(temp_sensor, &cbs, NULL);
|
||||
|
||||
Power Management
|
||||
^^^^^^^^^^^^^^^^
|
||||
|
||||
When power management is enabled (i.e. ``CONFIG_PM_ENABLE`` is on), temperature sensor will still keep working because it uses XTAL clock (on ESP32-C3) or RTC clock (on ESP32-S2/S3).
|
||||
|
||||
.. only:: SOC_TEMPERATURE_SENSOR_INTR_SUPPORT
|
||||
|
||||
IRAM Safe
|
||||
^^^^^^^^^
|
||||
|
||||
By default, the temperature sensor interrupt will be deferred when the Cache is disabled for reasons like writing/erasing Flash. Thus the event callback functions will not get executed in time, which is not expected in a real-time application.
|
||||
|
||||
There's a Kconfig option :ref:`CONFIG_TEMP_SENSOR_ISR_IRAM_SAFE` that will:
|
||||
|
||||
1. Enable the interrupt being serviced even when cache is disabled.
|
||||
2. Place all functions that used by the ISR into IRAM.
|
||||
|
||||
This will allow the interrupt to run while the cache is disabled but will come at the cost of increased IRAM consumption.
|
||||
|
||||
