This is a tool to simulate IMU filtering on a raw IMU log.
|

|
|
|
This requires activating the RAW_IMU bit on the LOG_BITMASK parameter.
|
|
|
|
|
Currently only supports the primary IMU and does not use batch sampling.

|
To run it:
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
python run_filter_test.py
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
This will open a file chooser dialog to select a log file.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Log file can also be specified from command line
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
python run_filter_test.py logfile.bin
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
To choose a smaller section of the log begin and/or end time can be specified in seconds.
|
|
|
|
|
E.g. to open only the log section between 60 and 120 seconds:
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
python run_filter_test.py logfile.bin -b 60 -e 120
|
|
|
|
|
```
