MSP430FR6047: Original Code, and adjusting software for other frequencies

Matthew Lynch

Part Number: MSP430FR6047

I received the EVM430-FR6037 board and proceeded to hook it up to 1MHz sensors and found that the device worked wonderfully using the USS Software. However, I have since loaded in some example programs into the device so that I could change the frequency of the pulse. This is due to the software not allowing me to go below the 780kHz. This too was a success. Not with the software but by loading in example code, adjusting, and monitoring with my scope. Not that I am here, I am stuck.

1. Can you send me the source files that come on the IC originally? Now that I see that it works, I want to be able to go back. The website has plenty of example codes, but I cannot tell which one, if any, is the original.

2. Can you assist me in changing your software to allow me to send 250kHz pulses?

Best Regards,

Matt L.

    Hi Matt,

    You can find the original demo code in the USSSW library by going to the following path:

    [USSLIB install path]\msp\UltrasonicWaterFR604x_02_40_00_00\examples\USS_Water_Demo

    If you haven't already downloaded it, you can do so here.

    As for adjusting the software to send 250kHz pulses: This device has a lower limit of 772kHz for water metering, as mention in the USS Design Center User's Guide. I am sure you could edit the code for the MSP430 to get past this, but the GUI is going to give you issues if you attempt to use a lower frequency than that no matter how you change the code.
