MPU 9250 and Arduino Uno #282

Open crosspatch opened 7 years ago

It keeps saying that the connection failed but as far as I understand, the 9250 and 9150 are more or less the same. Can someone assist me with this? Do I have to change something in the library or something?

VCC-3.3V GND-GND SCL-A5 SDA-A4 INT-2

Is the AD0 pin exposed, and if so, do you have it connected to GND or VDD? Or if it is not exposed, do you know whether it is internally connected to GND or VDD? If GND, then the slave address is 0x68, but if VDD, then it has to be changed in the .ino code to 0x69 instead.

it's connected to GND
