+
+## Overview
+
+The **FP5510** is a single 10-bit DAC with a 120mA output current voice coil motor, specifically designed for autofocus operations. It is commonly used in cameras, smartphones, and other electronic devices requiring focus adjustments.
+
+## Using FP5510 in MaixPy
+
+MaixPy supports the operation of the `FP5510` through the `FP5510` object.
+
+Example Code:
+
+```python
+from maix.ext_dev import fp5510
+
+fp = fp5510.FP5510()
+
+fp.set_pos(value)
+position = fp.get_pos()
+print(f'set position to {position}')
+
+```
+- Use the `fp5510.FP5510()` method to construct an object for controlling the `fp5510`. Typically, the FP5510 may have slave addresses of `0x0e` or `0x0c`. You can specify the slave address via the `slave_addr` parameter, e.g.:
+
+  > **Note**: If the address of fp5510 is found to change between 0x0e and 0x0c, it may be because the `FP5510` shares a reset pin with the `camera`. When the reset pin is enabled, the FP5510 address is `0x0c`. When the reset pin is disabled, the FP5510 address changes to `0x0e`.
+  
+  ```python
+  fp = fp5510.FP5510(slave_addr = 0x0c)
+  ```
+- Use the `set_pos` method of the `FP5510` class to set the position of the voice coil motor. The range is [0, 1023]. For example:
+
+  ```python
+  fp.set_pos(500)
+  ```
+- Use the `get_pos` method of the `FP5510` class to get the position of the voice coil motor. For example:
+
+  ```python
+  position = fp.get_pos()
+  print(f'set position to {position}')
+  ```

+## FP5510 简介
+
+FP5510是一款单10位DAC,具有120mA输出的电流音圈电机,专为自动对焦操作设计,常用于相机,手机等需要对焦的电子设备.
+
+## MaixPy 中使用 FP5510
+
+MaixPy支持使用`FP5510`对象来操作`fp5510`
+
+示例代码:
+
+```python
+from maix.ext_dev import fp5510
+
+fp = fp5510.FP5510()
+
+fp.set_pos(value)
+position = fp.get_pos()
+print(f'set position to {position}')
+
+```
+- 使用`fp5510.FP5510()`方法构造一个操作`fp5510`的对象.一般情况, fp5510可能有`0x0e`和`0x0c`两种从机地址, 通过`slave_addr`参数指定从机地址, 例如:
+
+  > 注意: 如果发现fp5510的地址在`0x0e`和`0x0c`间变化,可能是因为`fp5510`与`摄像头`共用了reset引脚,当使能reset脚时fp5510地址是`0x0c`, 当失能reset脚时fp5510地址是`0x0e`
+
+  ```python
+  fp = fp5510.FP5510(slave_addr = 0x0c)
+  ```
+- 使用`FP5510`类的`set_pos`方法来设置音圈电机的位置,范围为[0, 1023], 例如:
+
+  ```python
+  fp.set_pos(500)
+  ```
+- 使用`FP5510`类的`get_pos`方法来获取音圈电机的位置, 例如:
+
+  ```python
+  position = fp.get_pos()
+  print(f'set position to {position}')
+  ```
