The information on this page refers to firmware v2.74 and higher.
The STorM32 provides a filter section to filter the gyro and accelerometer, using notch/band-cut filters.
Concept and Overview
The filters are organized into three identical filter banks, which are processed in series. That is, the data are feed into filter bank #1, the output of this bank is then feed into filter bank #2, and finally the output of bank #2 is feed into filter bank #3. This allows for a very flexible choice of filter arrangements.
The parameters of the filter banks are exemplarily described for filter bank #1. They are:
- Filter1 Source: Selects the filter source.
- Filter1 Center Frequency: Selects the center or cut-off frequency of the filter.
- Filter1 Bandwidth: Selects the bandwidth for notch or band-cut filters.
- Filter1 Attenuation: Selects the attenuation of the band-cut filters. “inf” results in a notch filter.
Filter Sources
Currently, the following data sources are available:
| “off” | The filter bank is inactive. |
| “gyro1 all” | The raw data of gyro1 are filtered. |
| “imu1 all” |
