# pga460

Source: drivers/distance_sensor/pga460 (opens new window)

# 使用

Ultrasonic range finder driver that handles the communication with the device and publishes the distance via uORB.

# 参数描述

This driver is implented as a NuttX task. This Implementation was chosen due to the need for polling on a message via UART, which is not supported in the work_queue. This driver continuously takes range measurements while it is running. A simple algorithm to detect false readings is implemented at the driver levelin an attemptto improve the quality of data that is being published. The driver will not publish data at all if it deems the sensor data to be invalid or unstable.

# 使用

pga460 <command> [arguments...]
 Commands:
   start
     [device_path] The pga460 sensor device path, (e.g: /dev/ttyS6)
