PGA460-Q1: Measuring Sludge Levels

Part Number: PGA460-Q1

Hello Guys,

Our customer is using similar design to the forum thread below. For now, he just want to measure the distance with the transducer muRata MA58MF14-7N.

https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/840688/pga460-q1-interfaced-to-arduino-uno_source-code

But when he tried to get some data, he receive the weird data on the attached image. What do you think could be the issue?

Thanks and regards,

Art

    Hi Art,

    The issue is most likely from a mismatch in the selected baud rate and the baud rate of the terminal window.  In the screenshot, the customer selected a baud rate of “19200” by pressing “1” from the UART baud rate selection options.  However, if you look at the bottom of the terminal window, you notice that the terminal is configured for a baud rate of 9600. 

    To fix this issue, the customer can configure the baud rate for 9600 by pressing “0” instead of “1” for the UART baud rate selection option. 

    Regards,

    Mekre
