has anyone used this evaluation board for use with 300KHz transducers?

I am having difficulty setting it up and keep getting unknown errors.

Hi, can you describe the errors you are getting? Also, take a look at this e2e thread and the links within it for setting up the transducers with the board: https://e2e.ti.com/support/microcontrollers/msp-low-power-microcontrollers-group/msp430/f/msp-low-power-microcontroller-forum/990081/evm430-fr6043-how-can-i-connect-transducer-to-the-evaluation-board

hello,

the errors i keep getting ate 'DTOF-shift value was greater than maxsampleshift' + 'Time between measuremtns is greater than UPS0 to UPS1 gap'

I am trying to measure the air flow within a 21mm pipe so my transducers are separated by roughly 30mm of air and they are in the wetted areas so there is no change in medium between the transducers.

also keep getting the 'no signal in up and downstream' but the transducers are definitely connected.

Hi,

For your first error, 'DTOF-shift value was greater than maxsampleshift', take a look at this e2e thread regarding the same problem: https://e2e.ti.com/support/microcontrollers/msp-low-power-microcontrollers-group/msp430/f/msp-low-power-microcontroller-forum/809445/ccs-evm430-fr6047-dtof-errors.

For your second error, 'Time between measuremtns is greater than UPS0 to UPS1 gap', take a look at this e2e thread: https://e2e.ti.com/support/microcontrollers/msp-low-power-microcontrollers-group/msp430/f/msp-low-power-microcontroller-forum/728740/evm430-fr6047-increase-ups0-to-ups1-sampling-delay.

For your final error, 'no signal in up and downstream', take a look at this similar thread: https://e2e.ti.com/support/microcontrollers/msp-low-power-microcontrollers-group/msp430/f/msp-low-power-microcontroller-forum/660861/msp430fr6047-getting-no-signal-detected-in-up-and-downstream-channel-error.

This should help you troubleshoot your error but let me know if you have any follow up questions.

Thank you, I will look through those and get back to you if I still have any issues.
