kGetFIRFiltersResp (frame ID 14
d
)
This is the response to kGetFIRFilters and it has the same payload definition as
kSetFIRFilters.
7.7.3 Power Down/Up
For certain applications it is desirable to conserve battery power. To maintain accurate
heading readings in AHRS Mode generally requires continual sensor updates to the
Kalman algorithm. However, this is not the case in Compass Mode wherein readings
may be taken only when heading information is desired. Consequently, when in
Compass Mode the TRAX may be powered down when heading data is not required.
kPowerDown (frame ID 15
d
)
This frame is used to power-down the module. The frame has no payload. The
command will power down all peripherals including the sensors, microprocessor, and
RS-232 driver. However, the driver chip has a feature to keep the Rx line enabled.
The TRAX will power up when it receives any signal on the native UART Rx line.
kPowerDownDone (frame ID 28
d
)
This frame confirms the TRAX received a command to power down. The frame has
no payload.
kPowerUpDone (frame ID 23
d
)
This frame confirms the TRAX received a command to power up. (The TRAX will
power up when it receives any signal on the native UART Rx line.) The frame has no
payload.
