EVM430-FR6043: No output pulses with Ultrasonic Sensing Design Center

Part Number: EVM430-FR6043
Other Parts Discussed in Thread: UNIFLASH,


I'm trying to get started with the Ultrasonic Sensing Design Center (Water Mode), but so far, I wasn't able to measure anything with the oscilloscope. The way I understand it, I should at least be able to measure to output pulses at the pins X1 or X2. 

The Design Center also shows the error "No signal detected in up and downstream channel".

What I did:

- Download and install the Design Center and the Ultrasonic water meter

- Flash the image "MSP430FR6043EVM_USS_Water_Demo_LPM_02_40_00_00.txt" with the UniFlash tool

- Connect to the device, use the default configuration parameters

- Try out ADC capture and Frequency sweep and try to measure the outgoing pulses with an oscilloscope

- Increasing the Gain did not help

Did I miss something?

Best regards,
