rusty81 Posted July 30, 2014 Report Share Posted July 30, 2014 Hi all, I've bought an invesense evaluation board and I can't get it working, no way. I'm trying really every kind of code, connections, protocols... nothing. Now I've found that fantastic library, I2Cdevlib, and I'm a step forward, but still far from get it works. I'm using Arduino UNO, connections Vcc +5, SDA,SCK INT to PIN2 digital... same stuff as everyone I think. The MPU6050 it's recognized but I can't go over this error: Initializing I2C devices... Testing device connectioncs... MPU6050 connection sucessful Send any character to begin DMP programming and demo: Initializing DMP... DMP initialization failed (code 1) Someone have a clue of this? It seams that the device it's recognized but I can't talk to the DMP. I would like to communicate directly to the IMU, and do calculations on raw data acquired, but if I can use DMP it's better. Thanks in advance, your advise it's very appreciated Best Regards, Simone P.S. I'm using the example sketch from your lib repository ( MPU6050_DMP6 ) If I compile the other one (RAW), it works with a continuously stream of 0,0,0.... it's the board corrupt?

dsfgsho Posted August 4, 2014 Report Share Posted August 4, 2014 As a starting point, connect your MPU-6050 to 3.3V as it is designed to work with "Voltage - Supply:2.375 V ~ 3.46 V". The typical wiring is: VDD -> 3.3V GND -> GND INT -> Pin 2 on Uno VIO - > 3.3V SDA - > A4 SCL -> A5 Quote Link to comment Share on other sites More sharing options...
