Function Documentation

int move_valve

(

int

valve

)

Move valve to the position indicated by valve.

Parameters

Position

to move the valve: 0: Completely open 100: Completely closed 1-99: Partially open

Returns

Number of iterations needed to close valve. TODO: Unclear.

Here is the call graph for this function:

float32 read_Valve_POS

(

)

Read the current position of the valve.

Returns

Position of the valve as a percent, with 0 meaning completely open and 100 meaning completely closed.

uint8 zip_valve	(	char *	labels[],
		float	readings[],
		uint8 *	array_ix,
		int *	valve_trigger,
		uint8	max_size
	)

Moves first valve and inserts current value of valve_trigger into labels and readings arrays.

Parameters

labels	Array to store labels corresponding to each trigger result
readings	Array to store trigger results as floating point values
array_ix	Array index to label and readings
max_size	Maximum size of label and reading arrays (number of entries)

Returns

(*array_ix) + number of entries filled

uint8 zip_valve_2	(	char *	labels[],
		float	readings[],
		uint8 *	array_ix,
		int *	valve_2_trigger,
		uint8	max_size
	)

Moves second valve and inserts current value of valve_2_trigger into labels and readings arrays.

Parameters

labels	Array to store labels corresponding to each trigger result
readings	Array to store trigger results as floating point values
array_ix	Array index to label and readings
max_size	Maximum size of label and reading arrays (number of entries)

Returns

(*array_ix) + number of entries filled
