esc 4 in i issue
-
Hey @aiden
This is how we enable the driver in our board (e.g. FCv2):
https://github.com/PX4/PX4-Autopilot/blob/main/boards/modalai/fc-v2/default.px4board#L6The serial ports are kinda hard coded... e.g. FCv2
https://github.com/PX4/PX4-Autopilot/blob/3d61ab84c42ff8623bd48ff0ba74f9cf26bb402b/boards/modalai/fc-v2/src/board_config.h#L354Quick glance here and the v6c doesn't use this driver... we don't make that board so can't mess with it really, but it would be enabled here:
https://github.com/PX4/PX4-Autopilot/blob/main/boards/px4/fmu-v6c/default.px4boardSo I think you'd need to rebuild the FW and add the
MODAL_IO_DEFAULT_PORTto what you need, and enable the driver in the v6c config@modaltb
Accorinding @modaltb 's advice, I rebuilt the FW that named px4_fmu_v6c included modal_io driver.
In Qgroundcontrol, now i can see modal_io_ouput manual.but there is an issue what cannot touch param's value.
MODAL IO OUTPUT
configure :(param not available)
Bitrate : (Param not availabe)
RPM Min : (Param not availabe)
RPM Max : (Param not availabe)
ESC 1 spin Direction : (Param not availabe)
ESC 2 Spin Direction : (Param not availabe)
ESC 3 Spin Direction : (Param not availabe)
ESC 4 Spin Direction : (Param not availabe)can u tell me how to solve this issue?

@aiden , modal_io params are defined here : https://github.com/PX4/PX4-Autopilot/blob/main/src/drivers/actuators/modal_io/modal_io_params.c please make sure those are included in your PX4 build and you are using the correct parameter names.

@Alex-Kushleyev
Thank you for your advice.Here is my last Question.
I supplied power and put pwm in normanl esc(https://store.tmotor.com/goods-580-ALPHA+40A+6S.html), motor can spin.
Is it possible to operate moter with voxl 4 in 1 esc like above way? (without uart function like normal esc )
when i did that experiment, it didn't work.

@aiden , I am sorry but at this time we do not support direct PWM input to ModalAI ESC.

@Alex-Kushleyev
Here is last question.
When using a script to update parameters and run the motor, the motor's response is not always consistent.it seems like script cannot set whole motor's params.
because after update param first time, i saw situation what id 0,1,2 motor spun normally but id 3 motor was not.after update param file second time, situation was changed like id 2,3 were normal and id 0,1 were not.
sometimes id 0,1,3 were normal.. and id 2 was not..
can u give me any advise in this issue?
p.s Already checked all motors weren't broken

@aiden , can you please clarify what you mean "spin normally"?
You can use a command
./voxl-esc-verify-params.py, which is part ofvoxl-esctools, to verify the parameters on all 4 ESCs. If one of the ESC channels has an issue with params, this tool should be able to tell you about an issue.Additionally, if you simply run
./voxl-esc-scan.py, if all four ESCs are found using the baud rate that is specified in your params, then all the params are OK. -

Alex
On our ESC the Mosfet driver has a feature called "under voltage lockout", so if the supply voltage drops to below about 4.5V (even for a very brief period of time), the Mosfet Driver will enter fault state and will not drive the mosfets. The Mosfet driver gets reset by ESC software before each start-up.
So if you are seeing that sometimes a motor is not even attempting to spin, you are likely connected to a weak power supply that causes voltage to drop very low and cause a fault in the Mosfet Driver chip on the ESC.
Even though your log is showing voltage of about 7.5V, it is possible that there was an even lower dip, because the data is printed is at very low rate, so we don't see the dip.

can you please provide output of
./voxl-esc-scan.py? it will give me information about exact firmware version.Also, how are you powering the ESC? it seems during start-up attempt the voltage is dropping from 11V to 7V during spin-up, which is not a good sign. Are you using a weak power supply?
