Function Documentation

MV_CC_ReadMemory()

def MvCameraControl_class.MV_CC_ReadMemory	(		self,
			pBuffer,
			nAddress,
			nLength
	)

Reads data from device register.

Parameters

handle	[IN] It refers to device handle / frame grabber handle.
pBuffer	[IN][OUT] It refers to the data buffer for saving memory value that is read (GigE Vision device memory value is stored based on big-endian mode, and memory value of other devices is stored based on little-endian mode).
nAddress	[IN] It refers to the memory address to be read. It can be acquired from Camera.xml file, in a form similar to XML node value of xxx_RegAddr.
nLength	[IN] It refers to the length of memory to be read.

Returns

Returns MV_OK for success, and returns corresponding Error Code for failure.

Remarks

Read the data from certain register of the device.

MV_CC_WriteMemory()

def MvCameraControl_class.MV_CC_WriteMemory	(		self,
			pBuffer,
			nAddress,
			nLength
	)

Writes data into device register.

Parameters

handle	[IN] It refers to device handle / frame grabber handle.
pBuffer	[IN] It refers to memory value to be written (GigE Vision device memory value is stored based on big-endian mode, and memory value of other devices is stored based on little-endian mode).
pBuffer	[IN] It refers to the memory address to be written to. It can be acquired from Camera.xml file, in a form similar to XML node value of xxx_RegAddr.
nLength	[IN] It refers to the length of memory to be written to.

Returns

Returns MV_OK for success, and returns corresponding Error Code for failure.

Remarks

Accesses device and writes a piece of data into a certain segment of the register.
