Function Documentation

void _thermo_hw_init

(

void

)

[inline]

Init hw associated with thermo-control.

Definition at line 172 of file hw_thermo.h.

void thermo_hw_off

(

ThermoDev

dev

)

[inline]

Turns off a specific device. This function is usefull to handle errors.

Definition at line 115 of file hw_thermo.h.

deg_t thermo_hw_read

(

ThermoDev

dev

)

[inline]

Read the temperature of the hw device dev.

Definition at line 105 of file hw_thermo.h.

void thermo_hw_set	(	ThermoDev	dev,
		deg_t	target,
		deg_t	cur_temp
	)			[inline]

Based on the current temperature cur_temp and the target temperature target, this function turns on and off specific triac channel and handles the freezer alarm. It may use also PID control for thermo-regolations.

Definition at line 139 of file hw_thermo.h.

ticks_t thermo_hw_timeout

(

ThermoDev

dev

)

[inline]

This function should return the timeout for reaching the target temperature.

Definition at line 81 of file hw_thermo.h.

deg_t thermo_hw_tolerance

(

ThermoDev

dev

)

[inline]

This function should return the temperature set tolerance.

Definition at line 57 of file hw_thermo.h.
