ESP32 ESP-IDF component for inclinometer (via optical rotary encoder)

Tested on

1. ESP32 ESP-IDF v6.0.0

SAST Tools

PVS-Studio - static analyzer for C, C++, C#, and Java code.

Features

1. Support up to 8 inclinometers on one device.

Attention

1. For correct operation, please enable the following settings in the menuconfig:

PCNT_CTRL_FUNC_IN_IRAM
PCNT_ISR_IRAM_SAF

Using

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

cd ../your_project/components
git clone https://github.com/aZholtikov/zh_inclinometer

In the application, add the component:

#include "zh_inclinometer.h"

Examples

#include "zh_inclinometer.h"

zh_inclinometer_handle_t inclinometer_handle = {0};

void app_main(void)
{
    esp_log_level_set("zh_inclinometer", ESP_LOG_ERROR);
    zh_inclinometer_init_config_t config = ZH_INCLINOMETER_INIT_CONFIG_DEFAULT();
    config.a_gpio_number = GPIO_NUM_26;
    config.b_gpio_number = GPIO_NUM_27;
    config.encoder_pulses = 3600;
    zh_inclinometer_init(&config, &inclinometer_handle);
    for (;;)
    {
        float angle = 0;
        zh_inclinometer_get(&inclinometer_handle, &angle);
        printf("Inclinometer position is %0.2f degrees.\n", angle);
        vTaskDelay(100 / portTICK_PERIOD_MS);
    }
}
