Function Documentation

powermux2_cfg_setup()

void powermux2_cfg_setup

(

powermux2_cfg_t *

cfg

)

Power MUX 2 configuration object setup function.

This function initializes click configuration structure to initial values.

Parameters

[out]

cfg

: Click configuration structure. See powermux2_cfg_t object definition for detailed explanation.

Returns

Nothing.

Note

The all used pins will be set to unconnected state.

powermux2_generic_write()

err_t powermux2_generic_write	(	powermux2_t *	ctx,
		uint8_t	data_in )

Power MUX 2 data writing function.

This function writes a desired number of data bytes starting from the selected register by using SPI serial interface.

Parameters

[in]	ctx	: Click context object. See powermux2_t object definition for detailed explanation.
[in]	data_in	: Data to be written.

Returns

• 0 - Success,
• -1 - Error.

See #err_t definition for detailed explanation.

Note

None.

powermux2_init()

err_t powermux2_init	(	powermux2_t *	ctx,
		powermux2_cfg_t *	cfg )

Power MUX 2 initialization function.

This function initializes all necessary pins and peripherals used for this click board.

Parameters

[out]	ctx	: Click context object. See powermux2_t object definition for detailed explanation.
[in]	cfg	: Click configuration structure. See powermux2_cfg_t object definition for detailed explanation.

Returns

• 0 - Success,
• -1 - Error.

See #err_t definition for detailed explanation.

Note

None.

powermux2_set_resistance()

err_t powermux2_set_resistance	(	powermux2_t *	ctx,
		float	resistance )

Power MUX 2 set resistance function.

This function set resistance for the desired current limit of the TPS212x 2.8-V to 22-V Priority Power MUX with Seamless Switchover on the the Power MUX 2 click board™.

Parameters

[in]	ctx	: Click context object. See powermux2_t object definition for detailed explanation.
[in]	resistance	: Resistance [ kOhm ] from 18 kOhm to 100 kOhm.

Returns

• 0 - Success,
• -1 - Error.

See #err_t definition for detailed explanation.

Note

None.
