void lis3dh_arch_init

(

)

Perform the platform specific part of the initialization process of the LIS3DH.

This function is expected to set up the SPI module for the LIS3DH.

void lis3dh_memcpy_from_device	(	const lis3dh_reg_addr_t	start_address,
		uint8_t *	buffer,
		uint8_t	count
	)

Read multiple bytes from the LIS3DH.

Parameters

start_address	The lower address of the source registers.
buffer	A buffer to write the read values into.
count	Number of bytes to read.

void lis3dh_memcpy_to_device	(	const lis3dh_reg_addr_t	start_address,
		const uint8_t *	buffer,
		uint8_t	count
	)

Write multiple bytes to the LIS3DH.

Parameters

start_address	The lower address of the target registers.
buffer	A buffer to read the values from.
count	Number of bytes to write.

uint8_t lis3dh_read_byte

(

const lis3dh_reg_addr_t

addr

)

Read a single byte from the LIS3DH.

Parameters

addr	The source register.

Returns

The value of the register.

int16_t lis3dh_read_int16

(

const lis3dh_reg_addr_t

lsb_addr

)

Read a 16-bit integer from the LIS3DH.

Parameters

lsb_addr

The lower address of the two source registers.

Returns

The value of the register, byte order depends on the big/little endian setting of the LIS3DH.

Note

The BLE bit of CTRL_REG4 will affect the byte order of the return value.

void lis3dh_write_byte	(	const lis3dh_reg_addr_t	addr,
		const uint8_t	value
	)

Write a single byte to the LIS3DH.

Parameters

addr	The target register.
value	The value to write.
