So the issue with the HW version happens when using MP’s Battery Monitor screen?

Yes. When ‘Cube HV Power module’ is selected and HW Ver is set to ‘Cube Orange’, It automatically switches to ‘Other’ sensor and blank on HW Ver.

Here its just a bit late (I had to watch in slow mo)

Hey @iampete
I uploaded a small video. Over time the sync loss is actually noticeable visually(I mean noticeable without slowing video down). Also yes, It’s not as bad as what happened in other F4 boards in Neopixel blog.

@iampete

Are you using BLHeli esc’s?

I’m using BLHeli ESCs on AUX1-4. Neopixel on AUX6. Rest is 5V stuff(Only power).

@iampete

I would guess if you used aux 1-4 it would be better/different.

I couldn’t use it on 1-4 because of need of 4 ports running same clock.

@iampete

What do you have on UARTs?

Have Herelink Telemetry on UART1 and ESC telemetry on UART2.

You have quite a bit of stuff using DMA, unfortunately I don’t think there is a anything we can do about this short of a fairly big re-structure of DMA handling. LED’s are right at the bottom of the list of things that get to use it, ESC’s and UARTs come first.

I appreciate that this doesn’t solve your issue, sorry.

No issues @iampete
What if I move this LEDs to scripting instead of AP_Notify?

[iampete (Peter Hall)]

Same problem, its a low level output issue. So it shouldn’t make any difference.

If you fancy doing some debugging, you could see if it gets better if you turn off Dshot.

I’ll try this!
I’ll remove ESC telemetry to start with.
