TDC1000-TDC7200EVM: I need to update the firmware, a working setup files and an opinion on my experimental setup

Christian Garcia83

Part Number: TDC1000-TDC7200EVM

Hi everybody,

I am trying to make a flowmeter using the TDC1000-TDC7200EVM and I am not getting any results still after more than a month of experimenting. I have read on the forum about this topic but haven't solved my problem yet. The flow chart on the GUI is giving chaotic values for a pretty solid experimental setup. I have a steel pipe with screwed on transducers at a 70 degree angel. The transducers operational frequency is 1MHz and I know that the soundwave gets transmitted through the medium (water for now) and back in to the EVM.
I have read that a stable experimental setup is crucial and I think that this setup really should give a some what ok flow measurement.

.I am attaching a photo of the experimental setup for opinions.

Also, the GUI says that i need revision 2,01 but I cannot find a way to update the firmware.

In conclusion, I need to update the firmware, a working setup file, guidance on why the graph could be giving chaotic values instead of a steady flow graph and an opinion on my experimental setup.

Any help is appreciated and more info about my current setup etc could be presented if needed=)

Hello,

The firmware upgrade procedure is described in the EVM user guide ( www.ti.com/.../sniu021a.pdf ) starting on page 24. If you are not able to update the firmware using the GUI, you can run the update procedure on its own by running the .exe file in this directory: C:\Program Files (x86)\Texas Instruments\TDC1000_7200EVM\MSP430 USB Firmware Upgrade Example

I have attached a config file that is set up to be used with an audiowell test pipe that has 1Mhz transducers separated by 72mm directly in line with the direction of flow. It is also set up for use with an impedance matching circuit that is described in this application note www.ti.com/.../snia020.pdf . You will need to change some of the settings to match your own setup.

Could you please log the data from the GUI and upload it here so I can see what kind of values you are getting?

Hi,

The link to the EVM user guide doesn't work for me, but I think i found the document you are reffering to and managed to update the firmware.

I've attached a file with the data from a measurement using the setup file you proposed. I wasn't able to load all the config parameters. The GUI says 49 out of 50, but it doesnt say which one the 50'th is.

Which settings do I need to change for my own setup and which are static? Me and my team have been trying to understand the setting "Interrupt mask". I am reading about it in this document:

https://www.terraelectronica.ru/%2Fds%2Fpdf%2FT%2Ftdc7200.pdf

on page 13 section §8.3.3.3

But I don't understand how to apply it or what it really does. I interpret it as a setting for a time-window, between the start pulse and the recieved pulse, where I tell the EVM to ignore everything outside of that time-window.

Another question, the TRIGGER UPDATE FREQ seems to be the setting that controls how often a deltaTOF measurement is done. Is it not possible to make more than 10 measurements per second? The lowest that setting can go is 100ms

Some versions of the GUI produce a different number of settings. If you get the error of 49 out of 50 settings, just click "Save config" again and reload it. This will update the config file to include the correct settings.

Please try this link instead http://www.ti.com/lit/an/snia020/snia020.pdf for the water flow app note that will help you select the proper register settings for your application.

The interrupt mask option will mask the output of the INTB pin. You can select which interrupts will actually be output as a digital pulse on the INTB pin. The interrupts will always show up on the interrupt status register within the part. It allows you to control which interrupts your microcontroller will see when it monitors the INTB pin.

It is possible to make measurements more quickly than 10 times per second. This limit is in place because of the speed of the USB communication for the GUI. In a different system that does not rely on communication with the GUI, the update frequency only depends on your clock frequency and the actual time of flight.
