Hi, I have a question here in upload_file. BMI2_INIT_DATA_ADDR=0x5e and write_len=46, does the following line of code write config_data to the address of 5e, 5f, 60, 61... till 8B? rslt = bmi2_set_regs(BMI2_INIT_DATA_ADDR, (uint8_t *)config_data, write_len, dev); thanks a lot. ... View more

Hi, all In function of bmi2_write_config_file(), I have a question for the following code. if (rslt == BMI2_OK) { /* Check the configuration load status */ rslt = bmi2_get_internal_status(&load_status, dev); /* Return error if loading not successful */ if ((rslt == BMI2_OK) && (!(load_status & BMI2_CONFIG_LOAD_SUCCESS))) { rslt = BMI2_E_CONFIG_LOAD; } } I read load_status = 0xff and rslt = 0x00. Does it mean that the bmi2_write_config_file() is successfully write the configuation to IMU 270?  from the code it is, but read an 0xff from the reg of 0x21, really means it has been successfuly initialised? Thank you in advance.   ... View more

Hi, All    After initialisation, I got the result as: The oldest data was removed. Continue... *** Accel(Raw and m/s2) Gyro(Raw and dps) data : 35 ******* ms2_X = 0.00, ms2_Y = -0.15, ms2_Z = 2.30 DPS_X = 16.54, DPS_Y = 15.56, DPS_Z = 521.67 ******* Accel(Raw and m/s2) Gyro(Raw and dps) data : 36 ******* ms2_X = 0.00, ms2_Y = -0.15, ms2_Z = 2.30 DPS_X = 16.54, DPS_Y = 15.56, DPS_Z = 521.67 ******* Accel(Raw and m/s2) Gyro(Raw and dps) data : 37 ******* ms2_X = 0.00, ms2_Y = -0.15, ms2_Z = 2.30 DPS_X = 16.54, DPS_Y = 15.56, DPS_Z = 521.67 ******* Accel(Raw and m/s2) Gyro(Raw and dps) data : 1 ******* ms2_X = -0.00, ms2_Y = -0.00, ms2_Z = -0.00 DPS_X = -0.06, DPS_Y = -0.06, DPS_Z = -0.06 ******* Accel(Raw and m/s2) Gyro(Raw and dps) data : 2 ******* ms2_X = -0.00, ms2_Y = -0.00, ms2_Z = -0.00 DPS_X = 15.56, DPS_Y = -15.20, DPS_Z = -0.06 ******* Accel(Raw and m/s2) Gyro(Raw and dps) data : 3 ******* ms2_X = -0.00, ms2_Y = -0.00, ms2_Z = -0.00 DPS_X = 15.56, DPS_Y = -15.20, DPS_Z = -0.06 ******* Accel(Raw and m/s2) Gyro(Raw and dps) data : 4 ******* I have following questions: 1. Is this the correct value or random value? 2. It seems that if my board doesn't move, the result keeps unchanged, and stop output. However, if I move my board, the data outputs, but sometimes no output, is that correct. 3. I use the module of: bmi_accel_gyro(void) and  it check the interrupt status as: while (indx <= limit) { /* To get the data ready interrupt status of accel and gyro. */ rslt = bmi2_get_int_status(&int_status, &bmi2_dev); bmi2_error_codes_print_result(rslt); /* To check the data ready interrupt status and print the status for 10 samples. */ if ((int_status & BMI2_ACC_DRDY_INT_MASK) && (int_status & BMI2_GYR_DRDY_INT_MASK)) { /* Get accel and gyro data for x, y and z axis. */ rslt = bmi2_get_sensor_data(&sensor_data, &bmi2_dev); bmi2_error_codes_print_result(rslt); ssprintf("\n******* Accel(Raw and m/s2) Gyro(Raw and dps) data : %d *******\n", indx); ssprintf("\n******* Accel(Raw and m/s2) Gyro(Raw and dps) data : %d *******\n", indx); I am quite confused by the output results.

Hi, All I am working on the BMI270 driver.    In the function of upload_file(), what does the following 2 lines mean?  rslt = bmi2_set_regs(BMI2_INIT_ADDR_0, addr_array, 2, dev);  rslt = bmi2_set_regs(BMI2_INIT_DATA_ADDR, (U8 *)config_data, write_len, dev); does it mean to set register BMI2_INIT_ADDR_0 with 2 bytes of addr_array? set register of BMI2_INIT_DATA_ADDR with 46 bytes of config_data? Questions 1: As index will increment from 0 to 8088 (which is the config_file size) the addr_array will also increased to 8088, but max value BMI270's register address is just 0x7f, will this cause a problem?  Question 2:  after I successfully run the upload_file function, I get internal_staus by rslt = bmi2_get_internal_status(&load_status, dev); and found that load_status is 0xff and  sensor_data.acc.x = -1; sensor_data.acc.y = -1; sensor_data.acc.z = -1; what is the problem for this result? Thanks in advance. Victor   ... View more
