hi, jimit here, Why I can not set the gyroscope rate 6.4Khz in BMI270? it does not support? ... View more

Hi, jimit here, I built my own BMI270 API for Arduino boards, and I have a question regarding the BMI270 interrupt function, I want to generate an interrupt Acceleration sensor data. but to us, a surprise interrupt generates without attaching an interrupt pin attach, and I don't know how? can you guide me? here is my code.   IMU imu = IMU(Wire); BMI imu1 = BMI();     void setup() {   Serial.begin(57600);   Wire.begin();   Wire.setClock(400000UL);   delay(100);   // imu.start();   // imu.setConfig();   // pinMode(9, INPUT);   // attachInterrupt(9, drdy, RISING);   imu1.start();   imu1.setInterruptPin();   imu1.setConfig(); }   void loop() {   // uint8_t buf[12] = {0};   int16_t ax = 0, ay = 0, az = 0;   // int16_t x1 = 0, y1 = 0, z1 = 0;   float x, y, z;   // imu.readAccSensor();   // x = imu.getAccl_X();   // y = imu.getAccl_Y();   // z = imu.getAccl_Z();   imu1.getINTstatus(&int_status);   int ret = ((int_status | _int_status) & BMI2_ACC_DRDY_INT_MASK);   _int_status = int_status;   _int_status &= ~BMI2_ACC_DRDY_INT_MASK;   // Serial.println(int_status);   if (ret)   {     imu1.getAccData();     ax = imu1.get_accX();     ay = imu1.get_accY();     az = imu1.get_accZ();     Serial.print(ax);     Serial.print(",");     Serial.print(ay);     Serial.print(",");     Serial.println(az);   }   Serial.println("new data");   // imu1.read(0x68, 0x0c, buf, 12);   // ax = buf[0] | (buf[1] << 8);   // ay = buf[2] | (buf[3] << 8);   // az = buf[4] | (buf[5] << 8);   // x1 = (int16_t)ax;   // y1 = (int16_t)ay;   // z1 = (int16_t)az;   // Wire.beginTransmission(0x68);   // Wire.write(0x1B);   // Wire.endTransmission();   // Wire.requestFrom(0x68, 1);   uint8_t data = 10;   data = imu1.check_event_id();   // while (Wire.available())   // {   //   data = Wire.read();   //   /* code */   //   // Serial.println(BMI3_GET_BITS(Wire.read(), BMI2_EVENT_FLAG));   // }   // Serial.println(BMI3_GET_BITS(data, BMI2_EVENT_FLAG));   /* Set accelerometer range */   // reg_data = BMI2_SET_BIT_POS0(data_array[1], BMI2_ACC_RANGE, config->range);   // Serial.print(",");   // Serial.print((int16_t)ax);   // Serial.print(",");   // imu1.read(0x68, 0x53, buf, 3);   // Serial.print(buf[0], BIN);   // Serial.print(",");   // Serial.print(buf[1], BIN);   // Serial.print(",");   // Serial.println();   delay(5); // Wait for 100ms before reading again } void BMI::setInterruptPin() {     write(BMI270_ADDRESS, 0x53, B1010);     delay(2);     write(BMI270_ADDRESS, 0x55, 0x00);     delay(2);     write(BMI270_ADDRESS, 0x58, 0x04);     delay(2); }   void BMI::getINTstatus(uint16_t *int_status) {     uint8_t data_array[2] = {0};     read(BMI270_ADDRESS, 0x1C, data_array, 2);     *int_status = (uint16_t)data_array[0] | ((uint16_t)data_array[1] << 8); }   uint8_t BMI::write(uint16_t address, uint16_t subAddress, uint16_t data) {     Wire.beginTransmission(address);     Wire.write(subAddress);     Wire.write(data);     return Wire.endTransmission(); }   void BMI::read(uint8_t addr, uint8_t reg, uint8_t *buf, uint8_t len) {     // uint8_t addr = 0;     Wire.beginTransmission(addr);     Wire.write(reg);     Wire.endTransmission();     Wire.requestFrom(addr, len);     while (Wire.available())     {         for (uint16_t i = 0; i < len; i++)         {             buf[i] = Wire.read();         }     } } ...

hi, jimit here, I recently buy a bmi270 IMU, for my flight controller project, I successfully initialize the sensor without any problem(writing a config file with help of a datasheet) now I initialize the sensor in normal mode and start pulling the acceleration sensor data, I set  ACC_range = 2G,  then I set the ODR 200Hz, bandwidth on res_avg16 mode, then I show now I see I get Acceleration on the Z axis 4175 - 4185 instead of  16384, I don't know why this happened then I check 0x1b Event resistor, I see I get Error of 1, means ACC_CONFIG error, I am pretty sure I write right resistor on my config file I can show you in my code,  please check my code and guide me what did I wrong, thank you! ...
