Can you include a link to the URM04 reference page? |
|
please have meaningful PR titles |

Orson and I found this driver that is much cleaner than the arduino code. seems to have less random waits and better defined functions. I think orson wil try and replicate this driver moving forward: https://github.com/vrxfile/ultrasonic_rs485_sensor_api/blob/master/main.cpp |

Sample Code for URM04Sensor This Fourth Commit follows the 'Sample Code for URM04Sensor' the code makes a lot more sense and is easier to understand. |

In this commit I added writing high or low to the trig_pin because apparently this is needed to trigger the reading mode and transmitting mode for the RS485 interface as seen in this documentation here. Just want to make sure that this is correct ? |

@cindyli-13 finished implementing the requested changes. After resolving some git issues. |

There was a problem hiding this comment.
@younesr1 Is it ok if the ultrasonic sensor read is blocking?
The serial was not being flushed properly as it was being called after function returned. Thus, I moved it before function returns.

This is working version for the urm04 driver
