this reduces self-heating of the sensor which reduces the amount of
altitude change when warming up. Apparently some individual sensors
are severely affected by this.
Unfortunately it raises the noise level, but Paul is confident it
won't be a significant issue
The commander used to consume the battery_status topic and write the
contents after some calculations into the system state. Instead, the
calculations now happen in library calls in systemlib/battery.
This moves the battery fields out of the vehicle_status message into the
battery_status topic.
This brought quite some changes in all modules that need battery
information. The current state is compiling but untested.
this causes only problems and is not supported by ANSI C. error caused:
fatal error: field '_buf' with variable sized type 'ubx_buf_t' not at the end of a struct or class is a GNU extension
the warning is:
error: ignoring return value of ‘ssize_t write(int, const void*, size_t)’, declared with attribute warn_unused_result [-Werror=unused-result]
- Note that the simulator still uses gpssim by default
- now the gps module can be used in the SITL. this makes it possible to test
the real gps HW under POSIX
additional steps needed to use it:
- in the rcS_jmavsim_iris, make sure to start the gps instead of gpssim:
gps start -d /dev/ttyACM0 -s
- disable the mavlink serial connection in simulator_mavlink.cpp,
openUart(PIXHAWK_DEVICE, 115200);
- this also fixes a memory leak in the gps module
This adds a call on startup of the muorb on the aDSP side to use an
offset for hrt_absolute_call(). This means that the hrt_absolute_call()
on the appsproc (Linux) side should now match the one on the aDSP
(QURT) side.
The accuracy still needs to be determined.
