Set

SERVO_BLH_OTYPE to 0 (default)
SERVO_BLH_MASK to 0 (default)
SERVO_BLH_3DMASK to 0 (default)

Then after connecting to Mission planner what does this message say in the Messages screen?

I dont see tomorrow check and try your setting share results

Bi-directional dshot support ?

You are using the Bdshot firmware? And, you should be using the latest Stable or beta version not the Dev version unless there is a compelling reason to do so.

That doesn’t tell me anything. Why bother with Betaflight if you want to run Arducopter? Did you flash the Arducopter Bdshot version of firmware to the Skystar Board? It will show in the messages screen also. Post a screen capture (not a photo) of the messages screen after connection.

I know
I see article what a saying

There isn’t a bdshot version of this board - they are sending me one

OK, no Bi-directional Dshot and I see why you are using the -Dev version. Anyway from default you only need to set these 3 parameters for Standard Dshot:
MOT_PWM_TYPE to 6
SERVO_BLH_AUTO to 1
SERVO_DSHOT_ESC to 1

Trying
MOT_PWM_TYPE to 6
SERVO_BLH_OTYPE to 0 (default)
SERVO_BLH_MASK to 0 (default)
SERVO_BLH_3DMASK to 0 (default)

And

MOT_PWM_TYPE to 6
SERVO_BLH_AUTO to 1
SERVO_DSHOT_ESC to 1

Same issue

Right because Chan 1,2 and 9 are configured for Neopixel not motor outputs. I suppose because those are all on Timer1. You could use Outputs 3,4,5&6
SERVO_BLH_MASK to 252
SERVO_BLH_OTYPE to 6

I wonder if you can simply disable Neopixel by setting NTF_LED_TYPES to 0. Might try that 1st.

14

Change the function on SERVO9 to -1

For future reference is that because 1,2 and 9 share the same timer?

16

Yes. 1&2 are using complimentary channels so if I do a bdshot version I will fix this (bdshot can’t use complimentary channels)
