Detailed Description

Function Documentation

ecg4_cfg_setup()

void ecg4_cfg_setup

(

ecg4_cfg_t *

cfg

)

Config Object Initialization function.

Parameters

cfg	Click configuration structure.

@description This function initializes click configuration structure to init state.

Note

All used pins will be set to unconnected state.

ecg4_enable_ldo_ctrl()

void ecg4_enable_ldo_ctrl	(	ecg4_t *	ctx,
		uint8_t	state )

LDO Control function.

Parameters

ctx	Click object.
state	0 - Disable LDO control 1 - Enable LDO control3

@description Function powers up or down control of LDO (Low Drop Out).

Note

The BMD101 contains an internal LDO which consists of a bandgap cell to generate a 1.2V reference followed by two separate unity gain buffers, for the analog and digital supplies.

ecg4_generic_read()

int32_t ecg4_generic_read	(	ecg4_t *	ctx,
		char *	data_buf,
		uint16_t	max_len )

Generic read function.

Parameters

ctx	Click object.
data_buf	Data buffer for read data.
max_len	The maximum length of data that can be read.

Returns

Number of reads data.

ecg4_generic_write()

void ecg4_generic_write	(	ecg4_t *	ctx,
		char *	data_buf,
		uint16_t	len )

Generic write function.

Parameters

ctx	Click object.
data_buf	Data buffer for sends.
len	Number of bytes for sends.

ecg4_init()

ECG4_RETVAL ecg4_init	(	ecg4_t *	ctx,
		ecg4_cfg_t *	cfg )

Initialization function.

Parameters

ctx	Click object.
cfg	Click configuration structure.

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

ecg4_module_reset()

void ecg4_module_reset

(

ecg4_t *

ctx

)

Reset module.

Parameters

ctx	Click object.

ecg4_responseReady()

uint8_t ecg4_responseReady

(

ecg4_t *

ctx

)

Response ready check function.

Parameters

ctx	Click object.

@description Function checks if a response is ready.

ecg4_uart_isr()

void ecg4_uart_isr	(	ecg4_t *	ctx,
		uint8_t	rx_dat )

Uart Interrupt Routine function.

Parameters

ctx	Click object.

@description Function performs the uart interrupt routine, reads a data from uart rx buffer and makes a response from the BMD101 device.
