I already can probe and read out data from the device successfully. And also reusing the "struct urb" is working. Both instances read out data alternatively. I can solve the problem by not reusing the "struct urb" but I would like to avoid that. My code follows the USB skeleton driver from Greg Kroah-Hartman who also reuse the "struct urb" for different reading requests.

The complete code can be found on pastebin. Here is a small excerpt of the read method and the USB request complete handler. Now, I allocate a new struct urb for each read request.

This avoids the problem with the messed up struct urb after an active read request is cancelled by the calling application. The allocated struct is freed in the complete handler. For now, it is okay to allocate a new struct urb for each single read request. The complete code of the kernel module is on pastebin. Learn more. Asked 5 years, 8 months ago.

Active 5 years, 8 months ago. Viewed 2k times. I use following ideas for my implementation: The kernel module methods should be re-entrant. Therefore, I use a mutex to protect critical sections. After submitting the USB read request, the calling process is sent to sleep until the asynchronous complete handler is called.Connect with our user community or reach out to our sales reps.

The compass must be calibrated however. Alternatively the compass can be first connected through an I2C splitter if other I2C devices are to be attached. ArduPilot supports up to 3 compasses.

APM 2. After connecting the external compass you will need to re-calibrate the compass if you had run this procedure for the internal compass. If using Copter 3. This module permits the GPS to be mounted separately from the flight control module so that it can have the best clear view of the sky and allows the compass to be distanced from interfering magnetic fields.

The recommended orientation is to mount the module with the arrow facing toward the front of the vehicle and in the same direction as the arrow on the autopilot. Compass Calibration in Mission Planner explains the simplest way to calibrate a compass mounted in the recommended orientation arrows for autopilot and compass facing to front of vehicle.

Advanced Compass Setup contains more detailed instructions for calibrating a compass if, for example, it has been mounted at some other orientation. Note ArduPilot supports up to 3 compasses. Connecting to APM 2. Note After connecting the external compass you will need to re-calibrate the compass if you had run this procedure for the internal compass.

Tip The recommended orientation is to mount the module with the arrow facing toward the front of the vehicle and in the same direction as the arrow on the autopilot.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

This needs to be reworked to try for the PVT message first, and only if that fails enable the others, otherwise we should be disabling the other messages to reduce processing time, buffer pressure and tighten the timing. We can actually remove this line if we move the baud to across the board.

There is no reason to configure it differently.

I never really liked the duplication here either so this is a move in the right direction. Was this overloading the bandwidth to the GPS?

Just curious I could see it being a larger concern with having to provide correction data now. Is there a better mavlink message for bringing this to the autopilot? And if not should we make one?

Or will it simply always be to big to fit in a mavlink1 packet? I strongly nominate we implement that message then instead and push GCS's at it for this implementation. Randomly interrupting our RTCM data messages sounds like a really poor idea and will cause semi erratic behavior, especially if you are also experiencing problems with your radio link.

Why would we accept nack's here? That seems like exactly what we don't want to accept, as that means it refused our desired change. I just updated the pull request to address the reason I added that line, it was around sbas config. But we should be failing prearm checks then.

Or really just check that it isn't enabled It requires the user to set a parameter, but thats absolutely fine for what it buys us.

We should just mark the check as passed and move on. This is in someways an existing bug I'd say, as we shouldn't ask for the SBAS if we aren't going to do anything with it. Have you confirmed that requesting the additional output protocols doesn't break any of the older u-blox hardware?

I'm specifically thinking 5 and 6's as I lack devices to test this against, I can test 7's and 8's here. It was only needed when we were configuring u-blox's to be at different rates depending on if they wanted raw logging.

Also worth noting that this will raise the baud rate on every u-blox GPS that the autopilot can talk to.

Robotic nurses? Green cities that respond to our every need? While we need imagination to conceive our shared tomorrow, innovation, commercialization, and implementation are, ultimately, what get it built. The high number of visible satellites allows the receiver to select the best signals. This maximizes the position accuracy, in particular under challenging conditions such as in deep urban canyons.
