    Re: BMA222. Incorrect acceleration values

     I changed my code to the CHIP-ID account, but I still get the value: FA. I will continue to try to establish a connection, thanks.

    Hi Sir:

        BMA253 chip id is 0xfa, maybe you used chip is BMA253.

        If you can read out all register values and 0x00 register value can match BMA2XX chip id, please forward these values to us to re-check.

    Hello.

    The attached file contains the values ​​of all registers of my accelerometer. There is a feeling that only 1 axis works for me. Almost all register values ​​are in standard state.

    Hi Sir:

        Checked your register values, didn't find the error value.

        Actually after softreset, 3 axis sensor data can be outputed without any register configuration.

        Did you mean only 1 axis data is correct and changing? Could you exchange another sensor or another board to have a try?

        Checked 0x02/0x04/0x06, new_data_x/new_data_y/new_data_z were all 1 mean the corresponding sensor data had been update respectively.

        If needed, my example code can be provided as your reference.

        Did you have a softreset during initialization before reading sensor data?
