We are currently in the midst of developing an electronic system that among other things measures an angle. When researching and commissioning the Gyroscope BMG250, it was noticed that the fast offset compensation depending on the ambient temperature is unfavorable and thus deviates too far from zero. Data sheet BST-BMG250-DS000-02 on page 47 explains a possibility to adjust the resolution of the offset between 0.12 and 0.98 deg/s and the range between 31.25 and 250 deg/s. The exact resolution results from the formula 0. 12 deg/s*2^Val(gyr_range_off). These settings must be made in register 0x70 alias NV_CONF. The description of this register on page 45 and in the register Map on page 25 however, show no possibility to make such a setting. Only a selection between I2C and SPI can be made.
Does somebody have a hint on how to adjust the offset resolution? Thank you very much.
