MPU's Sync

By miguel_azz , 20 August 2012

Is there anywhere to synchronize multiple mpu's ?
is there anywhere to synchronize mpus with other device's such as daq or cameras ?

Many of our MPU devices support an FSYNC pin, which provides for frame (or trigger) synchronization. For image stabilization, we recommend the IDG 2020 and IXZ -2020 products, both support an external frame sync pin.

Can you elaborate on how FSYNC synchronization works on the MPU-60xx? From reading the Reg Map, I see how to latch the FSYNC value (on the sample clock) and I see how to pass the FSYNC value to the INT output pin.

What I would like to do is use the FSYNC input as a convert pulse - only logging Accel/Gyro data to the internal FIFO when FSYNC is asserted.

The frame sync pin operates as a flag on one of the sensor data registers. It allows the motion tracking algorithm to get a precise start / stop trigger from an external source to use when analyzing the motion data. It is designed to capture windows of motion, such as while shutter is open on a still camera, or to operate while taking video input. Typically, the device would be configured for high speed operation when using FSYNC.
