Hi,
I use gyroscope on mangOH green. I read G-force every 1sec. After 3-5min I could not read values. After digging to find a reason of the behaviour, I have noticed mangOH has not detected I2C adresses. I dont use FIFO. Has someone experience the same problem? I use WP8548 processor.
Update - I run gyroscope and other I2C device in other process. I think I2C is not thread safe. Am I correct?
I have verified in WP8548. i am able to see below i2c devices with their address that are connected to i2c bus in mangoh green.

Hi,
I can see I2C addresses as well. But when I used I2C in 2 threads (one gyroscope, one other thing) I2C crasheed and all addresses disappeared. I have synchronized threads and everything is ok now.
