3.1.7 - SPRacing F3mini Dshot not working on channel 4 #3646

Closed RunningPenguin closed 7 years ago

RunningPenguin commented 7 years ago

Hello,

I build a new quad with the SPracing F3mini board and Kiss 24A ESCs. I updated the ESCs to FW 1.0.2 through FTDI cable. Then I updated the FW of the ESCs with serial passthrough - works perfect for me when the fastmode is deactivated. Thanks for these very cool feature!

After that I enabled Dshot for testing purposes and motor 4 was not spinning and the LED didn´t light up. I swapped the wires from ESC4 and ESC2 and the failure then appeared on the other motor/ESC. I swapped the wires with the ESC1 and ESC3 and the failure remains everytime on channel 4 of the FC. So all ESCs and motors are working on channels 1-3 and no motor/ESC is working on channel 4 in DShot mode.

In oneshot42 and oneshot125 mode all 4 ESC and motors are working so I´m thinking that the failure is in the mapping of the DShot signals to the actual pins.

I hope these bug isn´t duplicate and you could fix it fast with my description.

Thanks

@RunningPenguin @hydra As of 3.1.7, motor 4 (PWM4) of SPRACINGF3MINI is not capable of being used as Dshot output.

There may be an alternative pin you can use. Can you paste output lines from CLI command "resource list"?

RunningPenguin commented 7 years ago

Ah thanks, didn't know that. Now it makes sense that the motor4 output didn't work with version 3.1.0 and 3.2.0 also.

Output of "resource" there were no command with "list"

Hmm... 3.1.7 should accept "resource list". Can you try again?

Ah, I wanted dshot enabled, but this serves the purpose.

Okay, try this

(1) Rewire your motor 4 to PWM8.

(2) Use following commands to remap motor 4 to PWM8

resource motor 8 none
resource motor 4 a1
save
RunningPenguin commented 7 years ago

Thank you so much. It did the trick. For others you have to use the port declared with "7" on the top side of the PCB this is PWM8 like marked on the bottom side of the PCB. With the above commands and Port7 DShot is working on SPracing F3mini and 4 motors.

hydra commented 7 years ago

could you provide a config dump so that others reading this can see what you did?

RunningPenguin commented 7 years ago

I ignored one warning that A01 is already used by Serial_TX 11.

I've done the following:

it gave me a message that A01 is already used by "SERIAL_TX 11" ignored that and worked with DShot150, DShot300, DShot600.

Here is the dump.

Thank you so much. It did the trick. Good to hear that. Happy props now :)

@hydra Timer assignments may need some review for SPRF3MINI. There are too many DMA collisions.

Dear all, on my SPF3 Evo I installed last BF3.2.1. I'm using RS30A lite blheli_s with oneshot125 all 4 motor spin correctly, if use dshot300 only motor 1,2,3 will spin. I read that is necessary remap motor 4 on another "pin" but I'm having some issue I receive this message:

A06 already assigned to SERIAL RX11

Can someone help me to remap the 4th motor?
