Hi, The BMA456 datasheet notes that a temperature measure of 0x80 corresponds to an invalid data. I believe this happens in the case the temperature is read twice during the 1.28s update period. The library does not handle this case as an error but instead returns a temperature of -105 deg C (if degree celsius range was asked). I suggest to return a specific error for this case so that the user of the lib can try reading the temperature a bit later. Thanks, ... View more

Hi, I configured the bma456 using the github library and sets the anymotion feature. When mapping the feature using BMA456_ANY_MOT_INT on BMA4_INTR2_MAP I get an interrupt triggered even if the board is still. After clearing the interrupt by reading the interrupt status register further interrupts are correctly triggered only when moving the board. By the way when checking the code I found the code of bma4_map_interrupt to be inconsistent because it clears only the bits when disabling a mapping but override the configuration when enabling a mapping. I believe : data[int_line] = (uint8_t)(int_map & (0x00FF)); data[2] = (uint8_t)((int_map & (0xFF00)) >> 8); should use |= instead of =. ... View more
