- try to handle mavlink system validity and present checks more consistently
- telemetry_status unify heartbeats and healthy flags across MAV_TYPE and MAV_COMPONENT (once it's outside of mavlink we don't care about the difference)
- add gimbal
- non-trivial perf counters (elapsed & interval) are relatively expensive
- if ESC and FFT notch filtering are enabled this reduces 6 updates (2 per axis) to 1
This enables flow control on CDCACM for the NuttX boards which fixes a
problem where HITL would stall.
The stall could happen if the hardware would be a bit too slow in
keeping up with the incoming messages. Often, this happened on arming
because the logger would take some time to log all parameters right at
the beginning.
The stall would then not recover due to NuttX bug where the rx interrupt
would not be restored correctly and instead only a slower watchdog would
release the next read. This watchdog takes 200ms which means it's hard
to impossible to get out of the situation without restarting sim and/or
PX4. For more information about the issue, see:
apache/incubator-nuttx#3633
As a workaround, until that bug is fixed, and because it makes sense
anyway, I propose to enable FLOWCONTROL for the serial via USB.
This enables the use case where the gimbal v2 protocol is used
between the ground station and the drone, and the gimbal v1 protocol is
used between the drone and the gimbal.
The existing implementation has about 100ms difference to a reference clock. With the changes this error less than 25us.
- Use sensor_gps messages with hrt timestamps as RTC reference and not the system realtime clock. The PPS interrupt can then be aligned with the GPS clock system.
- Keep fallback based on system RTC when no PPS pulse was captured
- camera_trigger module always publishes the camera_trigger msg (independent of the camera feedback)
- Use camera_trigger msg and set the feedback flag
- Subscribing modules determine if the message is relevant based on the feedback message
When using an FMU channel as PPS capture GPIO, the rtc_edge_time is now set as well. The delay between actual capture and callback is compensated with the elapsed time of the rtc clock.
- consider data clipped/saturated if it's INT16_MIN/INT16_MAX or within 1
- this accommodates rotated data (|INT16_MIN| = INT16_MAX + 1) and sensors that may re-use the lowest bit for other purposes (sync indicator, etc)
- Allocate and free the node name in uORBDeviceNode.
- Add protected build support by de-allocating the name with kmm_free, when
running in kernel side. strdup allocates from the kernel heap in NuttX kernel
space.
- Remove the CDev::unregister_driver_and_memory(), it is no longer used
