MPU9250 Address strange #5

Hi Kris,

I have the ladybug + MPU-9250 / BME280. I sold the 2 I2C pads and GND + VCC (no more)

-->Is it great?

I trried to run this script : https://github.com/kriswiner/Dragonfly/blob/master/MPU9250_BME280_BasicAHRS2_Butterfly.ino

but I have this error :

MPU9250 9-axis motion sensor... MPU9250 I AM 73 I should be 71 Could not connect to MPU9250: 0x73

If I replace, at ligne n°365, 0x71 by 0x73, the program run but I Have information providing from MPU9250 : In the following lines, the output of the serial :

ax = 0.00 ay = 0.00 az = 0.00 mg gx = 0.00 gy = 0.00 gz = 0.00 deg/s mx = 0 my = 0 mz = 0 mG q0 = 1.00 qx = 0.00 qy = 0.00 qz = 0.00 Gyro temperature is 21.0 degrees C Yaw, Pitch, Roll: 13.80, 0.00, 0.00 Grav_x, Grav_y, Grav_z: 0.00, 0.00, 1000.00 mg Lin_ax, Lin_ay, Lin_az: 0.00, 0.00, -1000.00 mg

You have chosen to use this sketch. This sketch uses an interrupt for data ready. Thus when you get to this part of the sketch:

// If intPin goes high, all data registers have new data if(newData == true) { newData = false; // reset newData flag readMPU9250Data(MPU9250Data); // INT cleared on any read

what do you think is going to happen?

In the sketch I define pin 8 as the interrupt pin. Is pin 8 connected to the MPU9250 INT? If not, this condition

newData == true

will never be true and you will never read any data.
