Kalman Filter Status – VBOX 3i
The table below shows the hex and decimal numbers associated with Kalman filter status.
The VBOX can have a number of these status flags active at the same time so the resultant number shown in VBOX Test Suite, VBOX Setup or a logged file will be a result of adding together the numbers of the active statuses shown below.
| Kalman Filter Status | Hex | Decimal |
|---|---|---|
| kf_Clear | 0x0000 | 0 |
| kf_NEWIMUVersion | 0x0001 | 1 |
| kf_TestMode | 0x0002 | 2 |
| kf_Use | 0x0004 | 4 |
| kf_Initialised | 0x0008 | 8 |
| kf_IMUDataFound | 0x0010 | 16 |
| kf_GoodLock | 0x0020 | 32 |
| kf_Reset | 0x0040 | 64 |
| kf_CoastingTimeout | 0x0080 | 128 |
| kf_IMUFound | 0x0100 | 256 |
| kf_Initialise | 0x0200 | 512 |
| kf_IMUmounting_error | 0x0800 | 2048 |

Example
Kalman Filter Status = 317 (13D Hex)
256: kf_IMUFound
32: kf_GoodLock
16: kf_IMUDataFound
8: kf_Initialised.
4: kf_Use.
1: kf_NewIMUVersion.
256+32+16+8+4+1 = 317
