Configure Spindle PWM Control on ArduinoDue gShield

[lumascet]

I have troubles configuring the correct pins for PWM spindle speed control on the ArduinoDue on edge-preview branch. My hardware follows the ArduinoDue Pinout: here.

so i added these lines to my settings file:

#define SPINDLE_ENABLE_OUTPUT_NUMBER 	12
#define SPINDLE_DIRECTION_OUTPUT_NUMBER 13
#define SPINDLE_PWM_NUMBER 		11

Building and uploading results in not being able to controll any of the pins 11, 12 ,13 when enabling the spindle. they stay at 3.3v. am i missing something? Hardware errors can be ruled out, since it had worked in the edge branch.

Which model of PWM are you using? 😄

I'm not sure if I understand your question correctly 😅, the pwm should be controlled via the p1 property i think, these are my settings of it:

{"r":{"p1":{"frq":10000,"csl":0,"csh":24000,"cpl":0,"cph":1,"wsl":0,"wsh":24000,"wpl":0,"wph":1,"pof":0}},"f":[1,0,8]}

I previously didn't have to alter the default gShield pinout configuration as it worked out of the box: gShield-pinout.h
Im not sure what exactly changed that these settings are not working anymore in edge-preview.

Gah. That's a brain-o on my part. Was thinking VFD (like these) for some reason. Doh. 🤦

Oh, yes indeed im using it in combination with a VFD like this one, with 0-10V is 0-24k rpm
The 0-3V3 to 0-10V conversion i realized through an Optocoupler.

Cool!

@giseburt has assigned this to himself, so you're in good hands when we has time to jump in.

I've not yet personally used a VFD at all, but I intend to when I get back into doing this stuff in a few months time. 😁

I've also run into this issue with Due on edge-preview. I tried different settings:

#define SPINDLE_ENABLE_OUTPUT_NUMBER        4
#define SPINDLE_DIRECTION_OUTPUT_NUMBER     5
#define SPINDLE_PWM_NUMBER                  6

I'm not sure if output number is supposed to correspond to pin number. I'm trying to use pin 11 on the Due.

Have you figured out anything yet?
