2. Automatic frequency detection.

Using

In an existing project, run the following command to install the components:

cd ../your_project/components
git clone http://git.zh.com.ru/esp_components/zh_ac_dimmer

In the application, add the component:

#include "zh_ac_dimmer.h"

Examples

#include "zh_ac_dimmer.h"

void app_main(void)
{
    esp_log_level_set("zh_ac_dimmer", ESP_LOG_ERROR);
    zh_ac_dimmer_init_config_t config = ZH_AC_DIMMER_INIT_CONFIG_DEFAULT();
    config.zero_cross_gpio = GPIO_NUM_16;
    config.triac_gpio = GPIO_NUM_17;
    zh_ac_dimmer_init(&config);
    zh_ac_dimmer_start();
    for (;;)
    {
        for (uint8_t i = 0; i <= 100; ++i)
        {
            zh_ac_dimmer_set(i);
            vTaskDelay(100 / portTICK_PERIOD_MS);
        }
        for (uint8_t i = 100; i > 0; --i)
        {
            zh_ac_dimmer_set(i);
            vTaskDelay(100 / portTICK_PERIOD_MS);
        }
    }
