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.

As the 43907 is not yet a broad market device and supported here on the IoT Community, please work with the local/regional Cypress sales team that enabled you with this product to setup the appropriate factory support.
