Function Documentation

max538x_init()

int max538x_init	(	struct max538x_dev **	device,
		struct max538x_init_param	init_param
	)

Initializes the communication peripheral and checks if the device is present.

Parameters

device	- The device structure.
init_param	- The structure that contains the device initial parameters.

Returns

ret - The result of the initialization procedure. Example: -1 - I2C peripheral wasn't initialized or the device is not present. 0 - I2C peripheral was initialized and the device is present.

Here is the caller graph for this function:

max538x_remove()

int max538x_remove

(

struct max538x_dev *

dev

)

Free the resources allocated by max538x_init().

Parameters

dev	- The device structure.

Returns

ret - The result of the remove procedure.

Here is the caller graph for this function:

max538x_set_voutput()

int max538x_set_voutput	(	struct max538x_dev *	dev,
		float	vout
	)

Sets the DAC output voltage using vout.

Parameters

dev	- The device structure.
vout	- voltage output to set.

Returns

ret - 0 if no error, else return error code of I2C transaction
