Hi Peabody,

You were spot on, wiring incorrect. Fixed this, then reduced the power output and it stopped a lot of its twitching. Simply awesome, it'll take me some time to tune it however it's great already. The pitch control via the CAN link is also incredible, no having to have separate wiring from the receiver in to the gimbal controller.

In the GCS everything is displaying correctly, the only thing I couldn't do was save values in the hardware tab for the gimbal. I changed these on the right side in the properties window and saved them fine.

Hoping to get it out for a fly on Wednesday, i'll share back after that.

Great to hear and wonderful to get the feedback. It would be nice to see your configuration and config file to get a sense of good configurations. Yeah really CAN is such the right thing to use for so many UAV peripherals. It's great to be able to use it to control the gimbal, limit the rotation angles, and eventually even pass information back to the FC (and via telemetry to hte GCS).

Which settings didn't save properly? Just the whole "save" button on the hardware page?

Once I have it running smoothly I'll be certain to share all settings, wiped off my feet with a fever so didn't get the opportunity to fly and test.

With the gimbal plugged in the "save" option next to "apply" on the hardware page disappears. So I used the controls on the right above properties to save.

If possible, could you point me to the value in the properties list that reflects the Max Rate (deg/s) - Pitch? Is this MaxDPS or am I being daft?

Not mad. There is BrushlessGimbalSettings.MaxDPS. I wouldn't mess with that, and it doesn't correspond to the setting on the front page.

There is also the StabilizationSettings.MaxRate and that is what the front page setting corresponds to. That is the max rate it will try and use when you do things like toggle an accessory0 channel that drives the pitch via CAN.

Issues with Sparky BGC unfortunately... right after spending the week getting it flying really nicely. Murphy has a nasty sense of humour ;) Anyway, here's a nice shot off the quad using the Sparky BGC...

Now back to issues... everything was flying perfectly then all of a sudden the Gimbal started pitching forwards and backwards violently. Landed the quad and it continued to pitch forward and back, pulled the battery power. Re-powered the quad and the gimbal no longer responds or goes through initiation.

Plugged in to the GCS the green light on the board lights up, and the orange light flashes. Unable to see the board in the GCS, and no luck in "rescue."

Appreciate any information/ideas to recover the board.

Is the red light pulsing just once or is it pulsing a number of times then pausing?

Good bet that the sensor isn't communicating with the board - especially if during the pitching it pulled on the cord. First, check the solder at both ends of the wire and make sure they are clean. Then untwist the wires and twist them around again tightly.

Hi Peabody,

The green light is solid and the orange light pulses once a second.

There's no breaks in the wires, I check this with a multimeter. The board doesn't show up in GCS either, with or without battery connected.

Regards,

Joel

Yeah a single pulse indicates it isn't getting the IRQ signal from the MPU9150 (sensor). Did you try the untwisting/retwisting the wires thing?

Also tonight I'll try and check the I2C communication rate and attempt to slow it down a bit more. That should make it more robust.

Are there any plans to produce and sell the gimbal and controller board?
