![]() Leaving the VIO pin unconnected results in a device which communicates but does not send any valid data 0xFF for everything. When the device powers on, it starts up in sleep mode, which must be explicitly disabled in order to begin normal operations. This is a very common problem, and fortunately one that is very easy to fix. The devices are offered in the same 4x4x0. The parts' integrated 9-axis MotionFusion algorithms access external magnetometers or other sensors through an auxiliary master I2C bus, allowing the devices to gather a full set of sensor data without intervention from the system processor. Do you have a question that isn't answered here or elsewhere in the source code, documentation, or examples for this device?Īsk away! Register Log in. ![]() ![]() This backwards discovery effort is incomplete and ongoing, and will hopefully end up in a feature-complete device library that supports full DMP configuration. Due to the lack of good publicly available documentation about the inner workings of this device, all DMP-related information has been reverse-engineered from I2C signal analysis correlated against the company-provided Embedded MotionApps software available on the InvenSense Developers Corner site. ![]()
