HI_MIPI_CONFIG_SENSOR_CLOCK

Applicable Products

Function

Configures the input clock frequency of the sensor.

Definition

#define HI_MIPI_CONFIG_SENSOR_CLOCK _IOW(HI_MIPI_IOC_MAGIC, 0x17, sns_clk_cfg_t)

Parameters

• HI_MIPI_IOC_MAGIC: indicates the magic number of MIPI RX ioctl commands.

  #define HI_MIPI_IOC_MAGIC 'm'

• 0x17: indicates the command identifier function and configures the clock frequency input to the sensor.
• sns_clk_cfg_t: indicates the clock configuration input to the sensor in slave mode.

  When the sensor works in slave mode or requires the AI processor to provide a clock, this command needs to be called in the process to configure the clock configuration information input to the sensor.

Returns

• 0: success
• -1: failure

Precautions

Before configuring the sensor clock, use the HI_MIPI_DISABLE_SENSOR_CLOCK command identifier to disable the sensor clock.
