TIDA-010050: TIDA-010050

Daniel Husztik
Prodigy 10 points
Part Number: TIDA-010050

Tool/software:

We are using TIDA-010050 to create a water meter monitoring device. We incorporated TIDA-010050 design into our own design, and created a monitoring device. We are testing the TIDA part now. 

Test setup: 

Texas chip from the reference design TIDA-010050 with Sensor Controller Studio software. Water meter is equipped with custom enclosure to hold our device on the flag.

My questions are the following: 

  • How can we fine tune the system for our needs? Is REFDAC_OFFSET what we need to increase or decrease to find the optimal point for the detection? 
  • Does time affect the detection? It seems, that if we start the water meter before starting the software, it is fine, but if the software runs for 20-30sec, the calibration is different, and so are the measured values and the sensitivity. 
  • How can we add a third coil to the system? We designed our panel with three coils, but we want to include the third one. Can we do it by changing a #define or should we rewrite the code?

    Hi Daniel,

    please, see answers below: 

    • How can we fine tune the system for our needs? Is REFDAC_OFFSET what we need to increase or decrease to find the optimal point for the detection? 

    TI: Yes, you can adjust REFDAC_OFFSET to find the optimal point for the detection.

    • Does time affect the detection? It seems, that if we start the water meter before starting the software, it is fine, but if the software runs for 20-30sec, the calibration is different, and so are the measured values and the sensitivity. 

    TI: Yes, calibration is a process that should be done in manufacturing, so you need to have the water meter start before the Software. The Calibration procedure assumes water flow is running as it is in the Initialization portion, which means it only runs once, while Event Handler A code runs periodically depending on the Event Trigger.

    So if you start the SW first, the calibration code will run on 0 or Non-flow condition and would fail.

    • How can we add a third coil to the system? We designed our panel with three coils, but we want to include the third one. Can we do it by changing a #define or should we rewrite the code? 

    TI: What is the function that the 3rd coil should have? Please, advise so we can make a proposal.
