    unexpected terminal output for AN BMF055 example project-data stream

    unexpected terminal output for AN BMF055 example project-data stream

    Hello, there

    I am learning the application notebmf055 example project-data streamand following the instructions step by step. But the terminal output is not shown as the note says. The sensor data is not displayed. Instead, regular messy codes appears on the terminal window.

     

    The connection between the computer and MCU is linked by UART module instead of USART module.

     

    Could you tell me why the messy terminal output appears and how to solve the problem?

     

    Thanks a lot!

    Can you please define, "regular messy codes" and "messy terminal output" 😉

    A screenshot would help a lot here !

    Is the baudrate set correctly?

    Thanks Dhank!

    Indeed it does look like a mismatch in baud rate. It could be that the BMF055 or your USB to UART clock are out of sync. To confirm which one, you would need an oscilloscope.

    Try to adjust the baud rate in your app in 1% increment, your should find a setting that matches pretty quickly.
