Hi, II have to reopen this thread because actually I am having a similar problem. I couldn't change the library in the way you mentioned to get arduino code compiled. Could you post/attach the part of the library you have changed? The message I received after compiling is same as yours: BMI270-Sensor-API-bmi270_v2.46.1/bmi2.h:1341:2: error: #endif without #if #endif /* BMI2_H_ */ I am also able able to detect correct chip ID (0x24) but accelerometer output independet of axis is still zero. ...

I skipped this step in hope it's not necessary becuase I have to figure out how to implement the BMI270_main.tbin. I will try. Thank you!! ... View more

Oh you are right. Thanks for the information. But output also shouldn't be zero although I am reading the x-axis on account of the noise. After asking for z-axis acceleration and shifting the eight MSB about one byte result is still zero 🤔. void loop() { Wire.beginTransmission(address); Wire.write(0x10); // reading LSB of Acc Wire.endTransmission(); Wire.requestFrom(address,2); if(2<= Wire.available()) { response = Wire.read()|Wire.read()<<8; } Serial.println(response); } Thanks so far!!   ...

Thanks for your response but unfortunately I coulndn't solve the problem. I changed the code as follows but output is still zero. #include <Wire.h> //I2C Arduino Library #define address 0x69 //I2C 7bit address int response; void setup(){ //Initialize Serial and I2C communications Serial.begin(9600); Wire.begin(); delay(100); // Wire.setClock(400000UL); // setting IMU270 in normal mode Wire.beginTransmission(address); Wire.write(0x7D); //PWR_Control Register Wire.write(0x0E); // enable acquistion of acc,gyro and temp Wire.endTransmission(); delay(100); Wire.beginTransmission(address); Wire.write(0x40); // Acc config Wire.write(0xA8); // Wire.endTransmission(); delay(100); Wire.beginTransmission(address); Wire.write(0x42); // Gyro config Wire.write(0xA9); Wire.endTransmission(); delay(100); Wire.beginTransmission(address); // Wire.write(0x7C); // PWR config Wire.write(0x02); Wire.endTransmission(); delay(100); // Wire.beginTransmission(address); // Wire.write(0x7E); // soft reset in CMD // Wire.write(0xb6); // Wire.endTransmission(); } void loop() { Wire.beginTransmission(address); Wire.write(0x0C); // reading LSB of Acc Wire.endTransmission(); Wire.requestFrom(address,2); if(2<= Wire.available()) { response = Wire.read()<<8|Wire.read(); } Serial.println(response); delay(500); }   ...
