You still can use the interrupt feature but do NOT map it to physical interrupt pin and enable the pin out.  Then you can use your host MCU to polling the interrupt status register.   You can use step detect and no motion interrupt to achieve your target.  ... View more

We have API regular update plan. When we fix some bugs in API,  we will try to release it on the Github. But according to the configure string,  it is quite stable now,  we don't have plan to update it in near future. The detail content of configure file can not be shared to you but i can tell you it contains sensor configuration and also the inialization code.  Without it,  the sensor can not working properly.  ...

We are using the following compiler option: Compiler: gcc-linaro-arm-linux-gnueabihf-raspbian-x64 Command: -c -march=armv8-a/armv6 -mfloat-abi=hard -mfpu=vfp -mtls-dialect=gnu Can you cross check if it matches your complier option?  if not,  please provide your option to us.    ... View more

I go through the API again.  During initialize of sensor, we will give the following table content to created device structure.   In bmi2_get_config_file_version, we use BMI2_CONFIG_ID to look up the table.  but actually it is not defined in table with coresponding page id.  So the return will be 0.    This means your function call to this will not return correct value.  In case you want to distingruish if you initiliaze as context image or activity image,  you can try to check if the dedicated configure type is existing and able to read out.  For example:  BMI2_NO_MOTION is not included in context image,  if you are not able to find the feature type after initialize,  then you are using context image.  Hope this solution will help you.  const struct bmi2_feature_config bmi270_feat_in[BMI270_MAX_FEAT_IN] = { { .type = BMI2_MAX_BURST_LEN, .page = BMI2_PAGE_1, .start_addr = BMI270_MAX_BURST_LEN_STRT_ADDR }, { .type = BMI2_CRT_GYRO_SELF_TEST, .page = BMI2_PAGE_1, .start_addr = BMI270_CRT_GYRO_SELF_TEST_STRT_ADDR }, { .type = BMI2_ABORT_CRT_GYRO_SELF_TEST, .page = BMI2_PAGE_1, .start_addr = BMI270_ABORT_STRT_ADDR }, { .type = BMI2_AXIS_MAP, .page = BMI2_PAGE_1, .start_addr = BMI270_AXIS_MAP_STRT_ADDR }, { .type = BMI2_GYRO_SELF_OFF, .page = BMI2_PAGE_1, .start_addr = BMI270_GYRO_SELF_OFF_STRT_ADDR }, { .type = BMI2_NVM_PROG_PREP, .page = BMI2_PAGE_1, .start_addr = BMI270_NVM_PROG_PREP_STRT_ADDR }, { .type = BMI2_GYRO_GAIN_UPDATE, .page = BMI2_PAGE_1, .start_addr = BMI270_GYRO_GAIN_UPDATE_STRT_ADDR }, { .type = BMI2_ANY_MOTION, .page = BMI2_PAGE_1, .start_addr = BMI270_ANY_MOT_STRT_ADDR }, { .type = BMI2_NO_MOTION, .page = BMI2_PAGE_2, .start_addr = BMI270_NO_MOT_STRT_ADDR }, { .type = BMI2_SIG_MOTION, .page = BMI2_PAGE_2, .start_addr = BMI270_SIG_MOT_STRT_ADDR }, { .type = BMI2_STEP_COUNTER_PARAMS, .page = BMI2_PAGE_3, .start_addr = BMI270_STEP_CNT_1_STRT_ADDR }, { .type = BMI2_STEP_DETECTOR, .page = BMI2_PAGE_6, .start_addr = BMI270_STEP_CNT_4_STRT_ADDR }, { .type = BMI2_STEP_COUNTER, .page = BMI2_PAGE_6, .start_addr = BMI270_STEP_CNT_4_STRT_ADDR }, { .type = BMI2_STEP_ACTIVITY, .page = BMI2_PAGE_6, .start_addr = BMI270_STEP_CNT_4_STRT_ADDR }, { .type = BMI2_WRIST_GESTURE, .page = BMI2_PAGE_6, .start_addr = BMI270_WRIST_GEST_STRT_ADDR }, { .type = BMI2_WRIST_WEAR_WAKE_UP, .page = BMI2_PAGE_7, .start_addr = BMI270_WRIST_WEAR_WAKE_UP_STRT_ADDR }, }; ...
