sensor_service

Overview

sensor service is a system service, which will using fastrpc to get the sensor data ‘s fd in dsp side and create a local socket to send this fd to client side.

Note

When we want to change the sensor ‘s frame rate, we need modify the configuration file in /etc/sensors_info.conf and restart sensor service.

restart sensor service cmd

(ssh) systemctl restart sensor-service

Parameter List

Parameter Name	Comment
sensor_type	Currently, we only support IMU sensor in sensor service, which need write the gyro & accel sensor type. Note: If different sensors are configured with the same hardware, the frequency of hardware sampling will be the final set.
frame_rate	Because sensors support specific frame rates on different platforms, if a frame rate that does not match the specific frequency is set, it will automatically adapt to a frame rate one level higher than this
