Hi
I am using BMI160 shuttle board with Arduino Uno over SPI. Also I am using the Driver developed by Hanyazou GitHub - hanyazou/BMI160-Arduino. The connection is okay but the gyro results are incorrect. Can you please help me resolve the issue?
Please see the code below (The code is the example in the Hanyazou GitHub).
[code]#include <BMI160.h>
#include <BMI160Gen.h>
#include <CurieIMU.h>
//const int i2c_addr = 0x69;
void setup() {
Serial.begin(9600); // initialize Serial communication
while (!Serial); // wait for the serial port to open
// initialize device
Serial.println("Initializing IMU device...");
BMI160.begin(BMI160GenClass::SPI_MODE, /* SS pin# = */10);
//BMI160.begin(BMI160GenClass::I2C_MODE);
uint8_t dev_id = BMI160.getDeviceID();
Serial.print("DEVICE ID: ");
Serial.println(dev_id, HEX);
// Set the accelerometer range to 250 degrees/second
BMI160.setGyroRange(125);
Serial.println("Initializing IMU device...done.");
}
void loop() {
int gx, gy, gz; // raw gyro values
// read raw gyro measurements from device
BMI160.readGyro(gx,gy,gz);
// display tab-separated gyro x/y/z values
Serial.print("g:\t");
Serial.print(gx);
Serial.print("\t");
Serial.print(gy);
Serial.print("\t");
Serial.print(gz);
Serial.println();
delay(1);
}
float convertRawGyro(int gRaw) {
// since we are using 250 degrees/seconds range
// -250 maps to a raw value of -32768
// +250 maps to a raw value of 32767
float g = (gRaw * 250.0) / 32768.0;
return g;
}
