|
|
|
|
## Tested on
|
|
|
|
1. [ESP32 ESP-IDF v5.5.2](https://docs.espressif.com/projects/esp-idf/en/v5.5.2/esp32/index.html)
|
|
|
|
## SAST Tools
|
|
|
|
[PVS-Studio](https://pvs-studio.com/pvs-studio/?utm_source=website&utm_medium=github&utm_campaign=open_source) - static analyzer for C, C++, C#, and Java code.

|
|
## Attention
|
|
|
|
1. For correct operation, please enable the following settings in the menuconfig:
|
|
|
|
```text
|
|
PCNT_CTRL_FUNC_IN_IRAM
|
|
PCNT_ISR_IRAM_SAF
|
|
```
|
|
|
|
## Using
|
|
|
|
In an existing project, run the following command to install the components:
|
|
|
|
```text
|
|
cd ../your_project/components
|
|
git clone http://git.zh.com.ru/esp_components/zh_inclinometer
|
|
```
|
|
|
|
In the application, add the component:
|
|
|
|
```c
|
|
#include "zh_inclinometer.h"
|
|
```
|
|
|
|
## Examples
|
|
|
|
```c
|
|
#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);
|
|
}
|
|
}
|
|
```
