MSP430FR6047: Help with EVM430-FR6047

Part Number: MSP430FR6047
Other Parts Discussed in Thread: EVM430-FR6047, , MSP-FET

Hello,

I will buy the EVM430-FR6047 board to try the ultrasonic transducers that I am buying from STEMINC. I want to meassure water flow through a pipe so I think the 2mm thick (1 Mhz) and 15mm radius transducer should do it. Should I take into another consideration?

Also, if I want to use the board just with batteries, how should I program it so it will stay in low battery consumption mode?

Last thing, if I want to transfer water flow meassurments from the board to a web server. What boosterPack could you recommend me? (like CC3100BOOST pack for example??)

Thanks a lot,

David.

    Hi David,

    That type of transducer is typically used for level sensing applications. For water flow, I recommend something that can be mounted to the pipe better or even a pipe that is pre-fit with transducers. Have a look at the examples below from Audiowell.

    Transducers: www.audiowell.com/.../product-detail.aspx

    DN20/DN25 Pipe: www.audiowell.com/.../product-detail.aspx

    If you want to run with lowest power, there is a build configuration in the USSLib code example for LPM. You can select this build option in the CCS project by right clicking the project and selecting "Build Configurations", then select "LPM". This will put the MSP430FR6047 in LPM3 when it is not used.

    We do not have any code examples for something like a web server, but if the required pins are available on the booster pack header, you should be able to write some code to interface.

    Hi Eddie,

    Thanks for the answer, I am talking now with the guys from Audiowell. But just to be sure, the transducers from SISTEMICS can not be used for flow water meters, or they just have low performance for that purpose??

    Last question please, I will buy also the microcontroller (MSP430FR6047) alone because I would like to program it for a specific application. You told me that in order to program it, I will require the MSP-FET. Am I right by saying that this MSP - FET is capable of programing every MSP430xx microcontroler? (just wanna be sure I am not spending 115 dollars in one application). And also, I guess I would have to make my own PCB to connect the MSP-FET with the microcontroller (MSP430FR6047) and program it. Should I have anything else into consideration if I would like to program it?

    Thanks,

    David.

    Hi David,

    I have never seen these types of transducers used for flow metering. You could ask Sistemics if they have done any flow testing, but I would not expect good results.

    Yes, the MSP-FET can program all the MSP430 devices.

    When you design your PCB, I recommend basing it on the EVM as this will have the required components. You could leave out the eZFET circuit, USB COMM, and HID bridge portions of the board. You will probably want some type of interface to the outside world, so be sure you provide some interface(UART, I2C, SPI, etc). The EVM talks to a USB HID bridge over I2C. If you would like to use our GUI, you would need to include this in your circuit as well. To lower risk, I really recommend the getting the EVM or copying the MSP430FR6047 circuit exactly.
