  • MSP430FR50431: Writing to FRAM is not successful

    TI Thinks Resolved
    Part Number: MSP430FR50431 Hi, I'm trying to write a value to a location in FRAM, but the value is not written. The MSP430 DriverLib 2.91.13.01 sample uses the FRAMCtl_A_fillMemory32 API to write a value to a specific FRAM address. Modules used and…

  • MSP430FR50431: MSP low-power Requirements

    Part Number: MSP430FR50431 Other Parts Discussed in Thread: MSP430FR5043 We Have taken FR6043 Template Project and some of the Modifications as to make GPIO Pins output low. P1OUT = 0; P1DIR = 0xFF; P2OUT = 0; P2DIR = 0xFF; P3OUT = 0; P3DIR = 0xFF; P4OUT…

  • MSP430FR50431: possible bug while developing our own frequency sweep function similar to the one in Ultrasonic Sensing Design Center software

    Part Number: MSP430FR50431 Other Parts Discussed in Thread: EVM430-FR6043 Hi Team, Good day. I am posting this inquiry on behalf of our customer. We're developing a water flowmeter using MSP430FR50431 and USS library supplied by you. We have managed to…

  • RE: MSP430FR50431: USS drive of external FETs or bridge driver

    Hi, The ZFD means the zero-flow drift of the dTOF over temperature. You can find more related information about the ZFD through this app note. https://www.ti.com/lit/ug/tiduej6a/tiduej6a.pdf Best regards, Cash Hao

  • RE: MSP430FR50431: Cycle slipping caused presumably by a bug in the AbsTOF lobe tracking algorithm.

    Resolved
    Hello, sorry about the late reply. I have solved the issue, yes. First, make sure that the lobe tracking threshold is set correctly. #define USS_ALG_RATIO_OF_TRACK_LOBE (some number that makes sense) The tracking algorithm can sometimes get stuck tracking…
