# --- SPINDLE PWM CONFIGURATION ---

# Load and Add Functions
# (Ensure loadrt pwmgen and loadrt scale are at the top of your file)
addf pwmgen.make-pulses  base-thread
addf pwmgen.update       servo-thread

# 3. Connect Spindle Enable
# This turns the PWM generator on only when the spindle is active and needs to be eliminated.
# (removed) net spindle-on         spindle.0.on        => pwmgen.0.enable

#Inverted Voltage Corrections
# First you need to add the next two lines above
# loadrt not count=1
# addf not.0 servo-thread

# set the Frequency
# first we need to set a frequency for the PWM in order for it to smooth the output
setp pwmgen.0.pwm-freq 100.0

# Calibration
# When using a 0-10v output signal, you may need to invert the PWM output
# so that the 5 axis breakout board will output 0V at spindle off,and
# 10v when the spindle is full on. The Negative sign before the 60000 usually does this.
# unfortunately the resting (spindle off) voltage is 10.0V - bad -very bad!
# rather we leave everything alone and creat a not.0 variable that reverses the values
setp pwmgen.0.scale  60000
setp pwmgen.0.offset 0.0
setp pwmgen.0.enable 1

# Connect Spindle Speed Command
# This signal carries the RPM requested by G-code (S command)
net spindle-speed-cmd  spindle.0.speed-out => pwmgen.0.value

# Prepare to invert it
net spindle-pwm-raw    pwmgen.0.pwm      => not.0.in

# Connect and invert the PWM Output to Physical GPIO
# This is the "Writer" for GPIO18
net spindle-pwm-final  not.0.out           => hal_gpio.GPIO18-out
