About accessing embedded accelerometer
Account cancelled 2013-10-30 18:06:43 3390 Views0 Replies I have the cable with the MPU6050 and the white Data Logger Shield that came with it. I've connected the 4-cable pin to Serial 1 on the shield, and the 2-pin cable to I2C 1. Now I just need to know how exactly to access the MPU6050 data with an Arduino UNO board.
I've already run an Arduino program that reads OBD data through the serial connection, and this program works flawlessly. But now I want to also access accelerometer data, and I didn't see any sample code for this.
I've tried using the I2CDev library, which didn't work. Then I tried the MPU6050 library ([url=https://github.com/stanleyhuangyc/ArduinoOBD/tree/master/libraries/MPU6050]https://github.com/stanleyhuangyc/ArduinoOBD/tree/master/libraries/MPU6050[/url]) and guide ([url=http://playground.arduino.cc/Main/MPU-6050]http://playground.arduino.cc/Main/MPU-6050[/url]) that you provided. I couldn't get this to work either. In both cases, the connection to the I2C device would fail during initialization.
I saw that the web page for the OBD cable said the accelerometer was built into the OBD library, so I figure I have to use the OBD library somehow, but I don't know how. Can you please help?
