Been trying on and off for a couple days to get any data from this module and have had no luck. Really hoping someone might be able to help. I’m using an Arduino Micro and have it connected to the gyro as follows:
GND > GND
5v > VIN
A4 > SDA
A5 > SCL
Following is the code, sorry if it’s too long - I pared it down a bunch, currently I’m trying to just see the X axis.
#include <Wire.h>
int Addr = 105; // I2C address of gyro
int x, y, z;
void setup(){
Wire.begin();
Serial.begin(9600);
writeI2C(0x20, 0x1F); // Turn on all axes, disable power down
writeI2C(0x22, 0x08); // Enable control ready signal
writeI2C(0x23, 0x80); // Set scale (500 deg/sec)
delay(100);
}
void loop(){
getGyroValues();
Serial.print("Raw X:"); Serial.print(x / 114);
delay(500);
}
void getGyroValues () {
byte MSB, LSB;
MSB = readI2C(0x29);
LSB = readI2C(0x28);
x = ((MSB << 8) | LSB);
}
int readI2C (byte regAddr) {
Serial.print("readI2C");
Wire.beginTransmission(Addr);
Wire.write(regAddr); // Register address to read
Wire.endTransmission(); // Terminate request
Wire.requestFrom(Addr, 1); // Read a byte
//while(!Wire.available()) { }; // Wait for receipt
return(Wire.read()); // Get result
}
void writeI2C (byte regAddr, byte val) {
Wire.beginTransmission(Addr);
Wire.write(regAddr);
Wire.write(val);
Wire.endTransmission();
}
If I uncomment the while in the readI2C method I never get any output in serial monitor.
Any help appreciated.
Moderator edit: CODE TAGS dammit.
