Members

Member	Description
update	Whether the data configures the sensor register. HI_TRUE: The sensor register is configured. HI_FALSE: The sensor register is not configured.
delay_frm_num	Number of delayed frames for the sensor register. This variable is used to ensure that the exposure time and gain take effect at the same time.
int_pos	Position where the configuration of the sensor register takes effect. When the register is set to 0x0, the configuration of the sensor register takes effect at the short frame start interrupt. When the register is set to 0x1, the configuration of the sensor register takes effect at the short frame end interrupt. When the register is set to 0x10, the configuration of the sensor register takes effect at the short frame start interrupt. When the register is set to 0x11, the configuration of the sensor register takes effect at the short frame end interrupt. When the register is set to 0x20, the configuration of the register takes effect at the medium frame start interrupt. When the register is set to 0x21, the configuration of the register takes effect at the medium frame end interrupt. When the register is set to 0x30, the configuration of the sensor register takes effect at the long frame start interrupt. When the register is set to 0x31, the configuration of the sensor register takes effect at the long frame end interrupt.
dev_addr	Sensor device address.
reg_addr	Sensor register address.
addr_byte_num	Bit width of the sensor register address.
data	Sensor register data.
data_byte_num	Data bit width of the sensor register.
