# M300 : Play tone, Beeper support, as commonly found on usual LCD displays
|
|
# i.e. RepRapDiscount 2004 Smart Controller, RepRapDiscount 12864 Full Graphic
|
|
# This defines a custom I/O pin and a custom GCODE macro
|
|
# Usage: M300 [P<ms>] [S<Hz>] P is the tone duration, S the tone frequency.
|
|
# as it is based on a PWM duty cycle, the frequency won't be pitch perfect.

|
#pin: ar37
|
|
# Beeper pin. This parameter must be provided.
|
|
# ar37 is the default RAMPS/MKS pin.
|
|
#pwm: True
|
|
# A piezo beeper needs a PWM signal, a DC buzzer doesn't.
|
|
#value: 0
|
|
# Silent at power on, set to 1 if active low.
|
|
#shutdown_value: 0
|
|
# Disable at emergency shutdown (no PWM would be available anyway).
|
|
#cycle_time: 0.001
|
|
# PWM frequency : 0.001 = 1ms will give a base tone of 1kHz
|
|
#scale: 1000
|
|
# PWM parameter will be in the range of (0-1000 Hz).
|
|
# Although not pitch perfect.
