Detailed Description

The tcLatticeMIPI class provides a basic interface to the MIPI Deserializer bitstreams loaded on the Lattice parts for the HWK1411 FPGA (and potentially others)

Member Function Documentation

GetNumLanes()

int tcLatticeMIPI::GetNumLanes

(

uint8_t &

anNumLanes

)

Fetch the number of lanes the bitstream supports.

Parameters

[out]

anNumLanes

the supported number of lanes

Returns

non-zero on error

GetVersion()

int tcLatticeMIPI::GetVersion

(

uint8_t &

anVersion

)

Get the version of the MIPI bitstream

Parameters

[out]

anVersion

the version number

Returns

non-zero on error

Initialize()

int tcLatticeMIPI::Initialize	(	std::string	arSpiDevPath,
		std::string	CSName
	)

Initialize the MIPI SPI interface. open the SPIDEV device and the gpio for the chip select.

Parameters

arSpiDevPath	full path to the spidev device to use
CSName	name of the chip select pin in /sys/kernel/debug/gpio listing

Returns

non-zero on error.

IsAlive()

bool tcLatticeMIPI::IsAlive

(

void

)

Returns

true if the device is communicating properly.

ReadRegister()

int tcLatticeMIPI::ReadRegister	(	uint8_t	offset,
		uint8_t &	value
	)

Threadsafe register read routine.

Parameters

	offset	the register offset
[out]	offset	the value read

Returns

non-zero on error

ReleaseSPI()

int tcLatticeMIPI::ReleaseSPI

(

void

)

Release the SPI device. This can be used if the device needs to be temporarily controlled by another piece of software, etc.

Returns

non-zero on error

ReopenSPI()

int tcLatticeMIPI::ReopenSPI

(

void

)

Reattach the SPI device. This can be used after a call to ReleaseSPI

Returns

non-zero on error

reset()

int tcLatticeMIPI::reset

(

void

)

Reset the Lattice MIPI bitstream

Returns

non-zero on error.

WriteRegister()

int tcLatticeMIPI::WriteRegister	(	uint8_t	offset,
		uint8_t	value
	)

Threadsafe register write routine.

Parameters

offset	the register offset
value	the value to write

Returns

non-zero on error
