                                        # ESP SIMPLEFOC开环速度控制应用示例

本示例演示了如何在 ESP32 系列芯片上使用 `esp_simplefoc` 组件开发电机开环速度控制程序。具体演示的功能如下：

- 电机速度开环控制

## 如何使用该示例

### 硬件需求

1. 硬件连接:
    * 对于ESP32-S3芯片，串口连接至默认RXD0与TXD0，若需使用其他串口，需要在串口初始化部分修改对应的uart_num以及RXD与TXD。
    * 示例电机极对数为14,额定电压为12V。
    * 示例MOS预驱采用EG2133，并将LIN与HIN连接，采用3PWM驱动方式。
    * 示例硬件图纸: [单电机硬件](https://dl.espressif.com/AE/esp-iot-solution/docs/foc_hardware_single_bldc.pdf)
    > 不同类型电机与硬件需修改调试参数，**请确保在正确的参数下调试，谨防异常。**

### 编译和烧写

1. 进入 `foc_openloop_control` 目录：

    ```linux
    cd ./esp-iot-solution/examples/motor/foc_openloop_control
    ```

2. 使用 `idf.py` 工具设置编译芯片，随后编译下载，指令分别为：

    ```linux
    # 设置编译芯片
    idf.py idf.py set-target esp32s3

    # 编译并下载
    idf.py -p PORT build flash
    ```

    请将 `PORT` 替换为当前使用的端口号

### 示例输出结果

以下为开环控制log:

    > 不同类型电机与硬件需修改调试参数，**请确保在正确的参数下调试，谨防异常。**

### 编译和烧写

1. 进入 `foc_velocity_control` 目录：
