InitialError is zero (success), the other error is 7 ( ? ). Serial.print(" | GyZ = ") Serial.println(GyZ) Serial.print(" | GyY = ") Serial.print(GyY) Serial.print(" | GyX = ") Serial.print(GyX) Serial.print(" | Tmp = ") Serial.print(Tmp/340.00+36.53) //equation for temperature in degrees C from datasheet Serial.print(" | AcZ = ") Serial.print(AcZ) Serial.print(" | AcY = ") Serial.print(AcY) Serial.print("AcX = ") Serial.print(AcX)
Wire.write(0x3B) // starting with register 0x3B (ACCEL_XOUT_H) InitialError = Wire.endTransmission(true) Wire.write(0) // set to zero (wakes up the MPU-6050) #includeĬonst int MPU_addr=0圆8 // I2C address of the MPU-6050 The function in question only has 4 possible return values and 7 isn't one of them. What's odd is when I trace through the Wire library I find that there is no error code 7 defined. But for ever call after that I receive error code 7. On the very first call to initialize the MPU I receive a success error code. I'm using the code that is available on the Arduino web site with a slight variation I'm checking the error code on endTransmission and am printing it (I started to do this because I was getting all zero values back from my calls to read the MPU registers). Guidance to resolve this issue would be greatly appreciated.I'm using an ESP32 to try to read from an IMU, the MPU-6050. This same change does not work for my Arduino Zero board. However, a build for the Afafruit Metro M0 Express complete successfully when the micro controller application is set to Visual Micro (No IDE). The same error occurs when building for the Adafruit Metro M0 Express board when the micro controller application is set to Arduino 1.6/1.8. Prior to upgrading Atmel Studio 7 and the Arduino IDE, my code would build and upload successfully on Atmel Studio using vMicro.Īfter upgrading, a simple ino file that includes Wire.h builds and uploads properly via the Arduino IDE but Atmel Studio fails the build process for Arduino Zero boards as follows:Įxterns.h: 19:10: fatal error: Wire.h: No such file or directory I am using Atmel Studio and vMicro to build and upload code to Arduino Zero boards and Adafruit Metro M0 Express boards. I recently updated Arduino IDE to 1.8.10 and Atmel Studio.
