    How to configure the BMA456

    How to configure the BMA456

    Hi,

    i try to use the BMA456 accelerometer. The communication with the component is correctly done but I don't understand the way to send the configuration file.

    The register 0x5E is mentionned as the register to write this configuration file. This register is an 8 bit register.

    The configure file contain lot of entry, who I can write all the parameter with just one register?

    When I analyze the configuration file function in the design example, the register 0x5B and 0x5C are used but this register does not appear in the datasheet. 

    Could somewhone help me?

    Regards

    Inside BMA456,  we use DMA engine to copy the configure string written into 0x5E to desired internal memory space.

    0x5C and 0x5B is the DMA related register which is not listed in datahsheet. 

    If you don't separte the package into small piece,  you can also ignore it and directly write to 0x5E with whole package.

    In general,  just call our API,  this configure string download activity should be done easily.
