We require synchronized data for the accelerometer and gyroscope for the BMI088 with accurate sampling at 200 Hz e.g. 1 sample every 128 ticks of the 24-bit clock (time resolution -> 39.0625E-6 s), to make recording of at least 1 hour (720000 samples).
The data synchronization example (https://github.com/BoschSensortec/BMI08x-Sensor-API/blob/master/examples/read_synchronized_data_mcu/...) is only for the MCU and we wish to run the code on the PC.
The streaming examples do not provide accurate timing between samples (large variace in sample intervals)and rely on the development board's 48-bit clock.
We can collect data using the fifo for both the accelerometer and gyroscope, but do not know how to make the outputs of the two fifo synchronized. Is this possible on the PC?
We also do not know how to get the time stamp of each sample in the fifo - or is the timing of the fifo accurate enough that the sample timings can be inferred?
Any pointers or example code in this regard would be greatly appreciated.
We have configured I2C to access data from the IMU, and can retrieve data from the sensor.
What I mean is that we do not wish to use the Coines-mcu lib, but the Coines-pc lib. This means that we can not follow the read_synchronized_data_mcu.c example, as that uses the `coines_attach_interrupt` and `coines_detach_interrupt` functions which is only available in the coines-mcu lib.
The README for coinesAPI - APP3.0 MCU states:
### Unsupported APIs
Use the below APIs instead
This implies that when using the coines-pc API that the streaming functions should be used in there place. We implemented the streaming functionality, but found that the timing between samples in unstable - we want the data to be sampled strictly at 200 Hz. The obvious way to do this would be to use the FIFO, but we do not know how to sychronize the FIFO for the acc and gyro using the coines-pc API.
Can we synchronize the FIFO for the acc and gyro using the coines-pc API?
