Multiple Spindle with VFD code correction #48

Closed JoachimF closed 1 year ago

JoachimF commented 1 year ago

In driver.c line 1899

PWM is not initialized when VFD is enable

#if (!VFD_SPINDLE || N_SPINDLE > 1) && defined(SPINDLE_ENABLE_PIN)
//#if VFD_SPINDLE != 1 && defined(SPINDLEPWMPIN)

If VFD is set by default, PWM is set to 100%, I don't know where to change that. Is there a way to have PMW on I2S Pin?

Regards,

Joachim

Good catch, will fix in next commit.

If VFD is set by default, PWM is set to 100%, I don't know where to change that.

Set PWM as default and add M104 as a startup command ($Nx) to switch to the VFD?

Is there a way to have PMW on I2S Pin?

It may be possible with code changes - but I will not be able to look into that for a while. You can give it a try?

Set N_SPINDLE to 2 to have the PWM spindle enabled together with the VFD. In the Web Builder this can be done by checking Add PWM spindle in the General tab.

In an upcoming build I have added code to ensure the PWM spindle pins will be initialized to the off state on startup (if enabled).

The latest commit has code added for initializing the PWM output even if the PWM spindle is not the default. Handling of multiple spindles has been changed somewhat - see the readme.
