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! ...
