Function Documentation

void heater_print

(

uint16_t

i )

send heater debug info to host

Parameters:

i	index of heater to send info for

Referenced by process_gcode_command().

void heater_set	(	heater_t	index,
		uint8_t	value
	)

manually set PWM output

Parameters:

index	the heater we're setting the output for
value	the PWM value to write

anything done by this function is overwritten by heater_tick above if the heater has an associated temp sensor

void heater_tick	(	heater_t	h,
		temp_sensor_t	t,
		uint16_t	current_temp,
		uint16_t	target_temp
	)

run heater PID algorithm

Parameters:

h	which heater we're running the loop for
t	which temp sensor this heater is attached to
current_temp	the temperature that the associated temp sensor is reporting
target_temp	the temperature we're trying to achieve
