Fenix999 Posted May 25, 2014 Report Share Posted May 25, 2014 Hi, I'm trying to make a acceleration data logger, the Seeeduino Stalter seems for me the best fit, it already comes with RTC, battery, and SD card reader all build-in. I managed to get my arduino uno to work with the GY-52 with no issues. I'm trying to replicate the same in the Stalker with no luck. I'm using the example for the MPU-6050 and what I get is: Initializing I2C devices... Testing device connections... MPU6050 connection failed I have tried 3.3V, 5V, some 10k pull-up resistors on the SDA, SCL lines, but it doesn't want to work. I have tried the Stalker with another I2C sensor and it works... Does anyone has some ideas? I'm not sure if the problem has to do with some speed issues, has the stalker has a 8mhz clock. I have also tried the mpu 6050 with a arduino due and it works fine.
