MSP430FR6043: MCU050 frequency

Part Number: MSP430FR6043
Hello. At the webminar, they told me that the minimum pulse generation frequency on the MCU050 board is 133 kHz. When trying to generate pulses of this frequency (or any other frequency up to 157 kHz) in single tone mode, the USS application reports an error: "Pulse generation parametrs are invalid". How can I fix it? How soon will a software version be released that will allow working with lower frequencies (from 100-120kHz)?

Current software versions:
Gas Demo Application UltrasonicGasFR6043_02_20_00_12
USSSWLib USS-02_20_00_19
  • Hey Evgeny,

    I am reaching out to one of our USS experts who will provide more information soon.

    Thanks,

    Mitch

  • Hi Evgeny,

    The minimum excitation frequency possible with this device is 133kHz. In order to get to these lower excitation frequencies, the project must be recompiled with a PLL setting of 68MHz(instead of 80).  The GUI doesn't support request updates with configurations at these lower excitation frequencies so you can only view captures and waveform data after recompiling an image with this lower frequency excitation.
