◆ IMU_ACCEL_X_SENS

#define IMU_ACCEL_X_SENS 37.91

default accel sensitivy from the ADXL345 datasheet sensitivity of x & y axes depends on supply voltage:

256 LSB/g @ 2.5V
265 LSB/g @ 3.3V z sensitivity stays at 256 LSB/g fixed point sens: 9.81 [m/s^2] / 256 [LSB/g] * 2^INT32_ACCEL_FRAC x/y sens = 9.81 / 265 * 1024 = 37.91 z sens = 9.81 / 256 * 1024 = 39.24

what about the offset at 3.3V?
