Hi ~!
like above title, I want to use dual ping sonar with arduino leonardo .
We are making source codes using Arduino’s two serial ports at the same time and Arduino codes provided by Blue Robotics.
However, as in the code below, the value of serial 1 appears to be only 0.
Since data values appear when you connect to tx and rx alone, I don’t think it’s a problem with board pins, and I think there’s a problem with source code, can you help me?
/**
* This example is targeted toward the arduino platform
*
* This example demonstrates the most simple usage of the Blue Robotics
* Ping1D c++ API in order to obtain distance and confidence reports from
* the device.
*
* This API exposes the full functionality of the Ping1D Echosounder
*
* Communication is performed with a Blue Robotics Ping1D Echosounder
