Part Number: TIDM-LC-WATERMTR

Dear Sir,

I just bought the EVM430-FR6989 Evaluation Kit, and trying to start with playing with the demo,

my question is the LCD display two numbers it seems that the second one (down one) is showing the number of turns in direction while clockwise add anticlockwise minus ,

may i ask what is the second number represent?

thanks

Jeff

  • Hi Jeff
    Which demo you are running?We have four demos for LCD(Three is register level and one is driver lib level )
  • Hi Jeff

    Have you fixed the problem?

    HI Gary, i am running the LC sensor one ~

    thanks

    Hi Jeff
    The two numbers represent to numbers of turns. The upper one is detected by the infrared sensor result and the lower one is the LC sensor result.The infrared sensor is used to judge whether the LC sensor get the write number of rotation.

    HI Gary,

    a)
    thanks , but in my board when the motor turns, only 1 number(the lower LC one) will appear and change. How the board can detect the infrared sensor from the motor board?

    b) The other question , how cam i adopt my EVM430-FR6989 demo board to 3LC program>?
    As i run the 3 LC program it won't work. Thanks

    Hi Jeff
    Refer to: www.ti.com/.../slau611.pdf Page14
    This demo don't support 3LC sensor. It is necessary to use 3LC sensor. This device have two AFE which you can use to do the calibration and don't affect the measurement.But the device support 3LC sensor solution the code you should write by your self.
    You can refer to this document for detail: www.ti.com/.../slaa639.pdf
    By the way we have give the ESI GUI for the device you can refer to www.ti.com/.../flowesi-gui

    HI Gary,

    1)

    in slau611 P14 .  i cannot find any keywords saying that it does support 3LC

    2) the program i download for 3LC is from

    Water Meter Reference Design for Three LC Sensors, Using ESI Software

    and this is the one for 2 lc

    as in the picture in the top right hand side it seems that the DEMO BAORD MAY also support the 3LC , please help to take a look and thanks~

    Hi Jeff
    (1) The slau611 P14 table12 is to show you how the board can detect the infrared sensor from the motor board.
    (2)The 3LC and 2LC solutions use the same main board and motor board. The main difference is the number of LC sensors and the software. If you want to use the 3lc sensor you should down load the 3lc sensor demo to the board. The demo is in the link:
    www.ti.com/.../doclitexportcontrol.tsp
    You should install it and the source code is in the install path.
    Best regards

    HI Gary,

    Thanks for your reply, i have already implemented and download the 3LC however the program was loop at certain point, so what i do to resolve it?
  • In reply to Jeff Yu:

    Hi Jeff
    Have you setup the LC sensor correctly? You can try decrease the clearance between the LC sensor and the disk. For the more you should make disk rotate to finish the configuration.
    Best regards
