		uint8_t *	wr_buf,
		uint16_t	wr_len,
		uint8_t *	rd_buf,
		uint16_t	rd_len )

Generic transfer function.

Parameters

ctx	Click object.
wr_buf	Write data buffer
wr_len	Number of byte in write data buffer
rd_buf	Read data buffer
rd_len	Number of byte in read data buffer

@description Generic SPI transfer, for sending and receiving packages

c420mar_init()

c420MAR_RETVAL c420mar_init	(	c420mar_t *	ctx,
		c420mar_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.

c420mar_read_data()

float c420mar_read_data

(

c420mar_t *

ctx

)

Read data function.

Parameters

ctx	Click object.

@description This function reads the 16-bit current value from the SPI data register, and then normalizes and converts it to float.
