HCSR-04 interfering with MPU-6050

Hi,

Got a weird bug in my code or with my hardware I’m not exactly sure. Im hoping someone has come across this

fifoCount = mpu.getFIFOCount();
	while (fifoCount < packetSize) fifoCount = mpu.getFIFOCount();
	mpu.getFIFOBytes(fifoBuffer, packetSize);
	fifoCount -= packetSize;
	mpu.dmpGetQuaternion(&q, fifoBuffer);


	////Control
	char val = Serial.read();
	delay(10);
	frontDistance = fsonar.ping_cm();
	delay(10);
	rearDistance = rsonar.ping_cm();
	delay(10);
	leftDistance = leftsonar.ping_cm();
	delay(10);
	rightDistance = rightsonar.ping_cm();

The reading of the 4 sensors is 100% screwing with my MPU readings and I have no idea why.

-0.00 -0.04 -0.00 1.00
-0.00 -0.04 -0.00 1.00
-0.21 -1.66 0.87 0.00
-1.56 0.19 -1.29 -0.17

The first two readings are acurate but after that I get these kind of sporadic values on the breakout.

Has anyone any ideas?

Thanks!

Thanks for approving, I actually fixed the issue just before. When not using an interrupt mpu.resetFIFO(); will clear the data and stop it mucking with values.
