This ESP32 espressif IoT development framework (esp-idf) i2c peripheral driver was developed for the Austria Microsystems AS3935 franklin lightning sensor.  Information on features and functionality are documented and can be found in the `as3935.h` header file and in the `documentation` folder.

## Repository

The component is hosted on github and is located here: <https://github.com/K0I05/ESP32-S3_ESP-IDF_COMPONENTS/tree/main/components/peripherals/i2c/esp_as3935>

## General Usage

To get started, simply copy the component to your project's `components` folder and reference the `as3935.h` header file as an include.  The component includes documentation for the peripheral such as the datasheet, application notes, and/or user manual where applicable.

## Basic Example

Once a driver instance is instantiated the sensor is ready for usage as shown in the below example.   This basic implementation of the driver utilizes default configuration settings and monitors the interrupt on the AS3935.  When an event is detected the AS3935 interrupt pin is asserted and event is printed to the serial terminal.

```c
#include <as3935.h>

static void as3935_event_handler(void *event_handler_arg, esp_event_base_t event_base, int32_t event_id, void *event_data) {
    as3935_monitor_context_t *as3935_monitor_context = (as3935_monitor_context_t *)event_data;

    switch (event_id) {
        case AS3935_INT_NOISE:
            ESP_LOGW(APP_TAG, "as3935 device interrupt was noise related");
            break;
        case AS3935_INT_DISTURBER:
            ESP_LOGW(APP_TAG, "as3935 device interrupt was disturber related");
            break;
        case AS3935_INT_LIGHTNING:
            ESP_LOGW(APP_TAG, "as3935 device interrupt was lightning related");
            ESP_LOGW(APP_TAG, "Lightning distance: %d", as3935_monitor_context->base.lightning_distance);
            break;
        case AS3935_INT_NONE:
            ESP_LOGW(APP_TAG, "as3935 device interrupt was related to nothing");
            break;
        default:
            ESP_LOGW(APP_TAG, "as3935 device interrupt is unknown %li", event_id);
            break;
    }
}


void i2c0_as3935_task( void *pvParameters ) {
    // initialize the xLastWakeTime variable with the current time.
    TickType_t         last_wake_time   = xTaskGetTickCount ();
    //
    // initialize i2c device configuration
    as3935_monitor_handle_t monitor_hdl;
    as3935_config_t dev_cfg          = I2C_AS3935_CONFIG_DEFAULT;

    //as3935_init(i2c0_bus_hdl, &dev_cfg, &dev_hdl);
    as3935_monitor_init(i2c0_bus_hdl, &dev_cfg, &monitor_hdl);
    if (monitor_hdl == NULL) {
        ESP_LOGE(APP_TAG, "as3935_monitor_init handle init failed");
        assert(as3935_monitor_init);
    }
    //
    esp_err_t err = as3935_monitor_add_handler(monitor_hdl, as3935_event_handler, (void *)dev_cfg.irq_io_num);
    if (err != ESP_OK) {
        ESP_LOGE(APP_TAG, "as3935_monitor_add_handler failed");
    }
    //
    // task loop entry point
    for ( ;; ) {
        ESP_LOGI(APP_TAG, "######################## AS3935 - START #########################");
        //
        // handle sensor
        //
        ESP_LOGI(APP_TAG, "######################## AS3935 - END ###########################");
        //
        //
        // pause the task per defined wait period
        vTaskDelaySecUntil( &last_wake_time, I2C0_TASK_SAMPLING_RATE );
    }
    //
    // free resources
    //as3935_delete( dev_hdl );
    vTaskDelete( NULL );
}
