Release 3.8.5beta3, 14th April 2018
|
||||
-----------------------------------
|
||||
Release 3.8.5, 25th April 2018
|
||||
------------------------------
|
||||
|
||||
This is a safety release, fixing an issue where the external safety
|
||||
button can activate in flight on some boards, causing them to crash. A
|
||||
new parameter BRD_SAFETYOPTION is added which controls the behaviour
|
||||
of the safety button. The default is to de-activate the safety button
|
||||
when armed.
|
||||
This release includes small bug fixes and one safety fix. The changes
|
||||
are:
|
||||
|
||||
- fixed an issue where the external safety button can activate in
|
||||
flight on some boards, causing them to crash. A new parameter
|
||||
BRD_SAFETYOPTION is added which controls the behaviour of the
|
||||
safety button. The default is to de-activate the safety button when
|
||||
armed.
|
||||
|
||||
Release 3.8.5beta2, 28th March 2018
|
||||
------------------------------------
|
||||
- fixed default orientation of ICM-20948 compass for Here GPS
|
||||
|
||||
This is a minor release with three new features, all related to
|
||||
airspeed.
|
||||
- added support for dual airspeed sensors
|
||||
|
||||
The first is to support the MS5525 sensor on multiple I2C
|
||||
addresses. Two new values of the ARSDP_TYPE are introduced (4 and 5)
|
||||
for specific I2C addresses. This allows you to deconflict the MS5525
|
||||
from a MS5611 barometer on the same bus.
|
||||
- added support for the SDP33 airspeed sensor. This is still
|
||||
considered experimental. There are reports of it underestimating
|
||||
the aircrafts speed at higher altitudes.
|
||||
|
||||
The second is the addition of a driver for the SDP33 airspeed
|
||||
sensor. This is an interesting sensor sold by Drotek that doesn't need
|
||||
zero offset calibration for each flight. It is still considered
|
||||
experimental.
|
||||
- add support for the MS5525 airspeed sensor on multiple I2C
|
||||
addresses. Two new values of the ARSDP_TYPE are introduced (4 and
|
||||
5) for specific I2C addresses. This allows you to deconflict the
|
||||
MS5525 from a MS5611 barometer on the same bus.
|
||||
|
||||
The third new feature is dual airspeed sensor support, which allows
|
||||
you to have two independent airspeed sensors. At the moment the
|
||||
failover between the sensors is very simple (it will only failover if
|
||||
the primary stops communicating). More sophisticated failover methods
|
||||
will be introduced in the future. To enable a 2nd airspeed sensor set
|
||||
the ARSPD2_TYPE parameter to the type of the 2nd sensor. You can
|
||||
combine any types of sensor.
|
||||
|
||||
The beta2 release also corrects the orientation of the Here GPS 20948
|
||||
compass.
