K230 Sensor API Reference#

Overview#

The Sensor API is used to complete image sensor device operations including opening, powering on, initializing, mode switching, register read/write, and runtime parameter adjustment. This set of interfaces primarily corresponds to the sensor driver control surface and is typically used together with VICAP and ISP.

The current API header file is located at src/rtsmart/mpp/userapps/api/mpi_sensor_api.h, and the related data type definitions are located in k_sensor_comm.h and k_vicap_comm.h.

// 8. 关闭设备
kd_mpi_sensor_close(fd);

Notes#

fd Management: All operations depend on the fd returned by kd_mpi_sensor_open(). You must call kd_mpi_sensor_close() to close it after use.
Call Sequence: It is recommended to follow the order: Power on → Initialize → Configure → Enable stream.
Parameter Range: Before setting parameters such as gain and exposure, it is recommended to call the corresponding get_*_range() interface to obtain the valid range.
Sensor Differences: Different sensors may support different functions and parameter ranges, with specific capabilities determined by the driver.
Concurrent Access: Avoid multiple threads operating on the same sensor fd simultaneously.
Error Handling: All interfaces returning a non-zero value indicates failure. You should check the return value and handle it accordingly.
