About Chris89

We have implemented the interrupt-streaming-pc example from here https://github.com/BoschSensortec/BMI08x-Sensor-API/blob/master/examples/interrupt_streaming_pc/interrupt_streaming_pc.c We are using the BMI088 and the version 3 dev board. We have both the accelerometer and the gyro configured with ODR's of 200 Hz. The timestamps being reported are counting slow, by a factor of ~ 2X. E.g. it takes ~ 10 seconds to record 5 seconds of data with respect to the reported time stamps. Example time stamps from a block of 6 valid samples: valid sample count: 6 time stamps: 3073012389 time stamps: 3073015034 time stamps: 3073017702 time stamps: 3073020324 time stamps: 3073022980 time stamps: 3073025644 Time delta between the final two samples is 0.00266, where it should be closer to 0.005 for a sample rate of 200 Hz. The timestamps are calculated as: 48bit_timstamp / 30. Is the factor of 30 correct for the BMI088?  Something is clearly not being converted correctly as the delta between timestamps are out by a factor of ~2, but it takes approx twice as long to get a 5 second recording implying that the data is sampled at the correct rate, but the timestamps themselves are incorrect.  Any idea what we could be doing wrong? ...

We want to read time synchronised acceleration and gyroscope data from the BMI088 chip with the application board 3.0 using the COINES-PC lib, rather than the MCU lib. Is this possible? Could example code be provided if so? The read_synchronized_data_mcu example found here: https://github.com/BoschSensortec/BMI08x-Sensor-API/tree/master/examples/read_synchronized_data_mcu does not work when using the coines-pc lib as the `coines_attach_interrupt` function is only available for the mcu version of coines.  It is worth noting that the Development Desktop 2.0 outputs the acc and gyro data with synced timestamps, which implies that synchronisation is either assumed or infact can be run on the PC. ...
