    (question) Using Hx711_load cell  in BCM board

    hbkim

      my os is windows10 and develope environment is WICED Studio 4.1.1 IDE.

      my board is BCM43907(CYW43907).

      I want to use load cell on BCM43907(CYW43907). board. 

       

      First, I bought the product.

      (Hx711 breakout board : https://www.sparkfun.com/products/13879

      Load senseor Combinator : https://www.sparkfun.com/products/13878

      Load cell : https://www.sparkfun.com/products/10245  )

       

      Second,

      I checked the normal operation of the load cell through the "redbear duo" board (IDE: arduino).

      (refer to "SparkFun_HX711_test.zip (arduino code)" and  "hx711.zip(library)" )

       

      Finally, After properly connecting the pins (GPIO x2, GND, VDD3v3) and writing the library and code(using arduino code,library) , I tested it with the BCM43907 board, but there was a problem with the output of the value.(refer to "load_cell_test.zip ( wiced studio code ) " )

      The weight value is not stable.

       

      Is there a difference between the behavior of arduino code and the behavior of wiced studio code?

      Please help me figure out what's wrong.
