ITG-3200/5 not responding

I can’t get the numbers to match the action of rotating it by hand. It’s just a bunch of small numbers + and - less than 10, no matter how I rotate it. I have a 9DOF board. I’ve only connected 4 wires to Uno. What about Vcc? What about pullup resistors? The other 2 chips work fine over I2C.

Seems like there’s a delay. When I rotate the board the numbers sometimes respond a minute later?
I deleted my delay, but there was already delay(50) in loop. Can GyroRead() get behind?
Why are the numbers printed so slowly without delay(50)?
The chip is initialized at 1khz?
What does that mean?

I think it was working! With a shorter delay than 50.

But now I’m only getting 0,0,0 and Temp 82. I didn’t think I changed anything. I did not change the hardware or wiring. So I went back to the original Sketch I downloaded. There were many values less than 10 every time I ran it. Now all 0,0,0 for x,y,z.

Both the other 2 chips on the board still work. I didn’t touch or bump any of the wires on the board, they are secure. The same 4 wires are used for I2C for all 3 chips. So there were no shorts. The Sketch is the same. How can I “Reset” the ITB-3205 chip???

I don't know what happened, it started working again, more than just 0,0,0.

Another clue for the case of the lazy gyro: When I tap the gyro board, the numbers respond instantly from 2 to 50. Especially X. Regardless of the delay 5-50. But not when I turn it in any direction. How do I properly test this code?
