API for configuring and manipulating MUX 9 Click driver.

Any initialization code needed for MCU to function properly. Do not remove this line or clock might not be set correctly.

Function Documentation

mux9_active_channel()

err_t mux9_active_channel	(	mux9_t *	ctx,
		uint8_t	sel_ch )

MUX 9 active channel function.

This function enable is the selected channel of the ADG1438B Serially Controlled, ±15 V/+12 V/±5 V, 8-Channel/4-Channel, iCMOS Multiplexers/Matrix Switches on the MUX 9 click board™.

Parameters

[in]	ctx	: Click context object. See mux9_t object definition for detailed explanation.
[in]	sel_ch	: Selection of the desired channel [1-8].

Returns

• 0 - Success,
• -1 - Error. See #err_t definition for detailed explanation.

Note

None.

mux9_cfg_setup()

void mux9_cfg_setup

(

mux9_cfg_t *

cfg

)
