Detailed Description

SDH::cDSA is the end user interface class to access the DSACON32m, the tactile sensor controller of the SDH.

Class to communicate with the tactile sensor controller DSACON32m of the SDH

Bug:

cDSAException: Checksum Error on Windows console While communicating with the tactile sensor controller a "cDSAException: Checksum Error" might be thrown once in a while. This seems to happen only when the program is started from a native windows command console (cmd.exe), but not e.g. when the program is started from a cygwin console. Strange. Workaround is to catch the exception and ignore the frame.
=> Resolved in SDHLibrary-C++ v0.0.2.1
Problem was an overrun of the windows input buffer, e.g. on heavy processor load.

Constructor & Destructor Documentation

cDSA::cDSA	(	int	debug_level = 0,
		int	port = 1,
		char const *	device_format_string = "/dev/ttyS%d"
	)

Constructor for cDSA. This constructs a cDSA object to communicate with the remote DSACON32m controller within the SDH via RS232.

The connection is opened and established, and the sensor, controller and matrix info is queried from the remote DSACON32m controller. This initialization may take up to 9 seconds, since the DSACON32m controller needs > 8 seconds for "booting". If the SDH is already powered for some time then this will be much quicker.

Parameters

debug_level	- the level of debug messages to be printed: if > 0 (1,2,3...) then debug messages of cDSA itself are printed if > 1 (2,3,...) then debug messages of the low level communication interface object are printed too
port	- the RS232 port to use for communication. (port 0 = ttyS0 = COM1, port 1 = ttyS1 = COM2, ...)
device_format_string	- a format string (C string) for generating the device name, like "/dev/ttyS%d" (default) or "/dev/ttyUSB%d". Must contain a d where the port number should be inserted. This char array is duplicated on construction. When compiled with VCC (MS-Visual C++) then this is not used.

Definition at line 596 of file dsa.cpp.

cDSA::cDSA	(	int	debug_level,
		char const *	_tcp_adr,
		int	_tcp_port = 13000,
		double	_timeout = 1.0
	)

Constructor for cDSA. This constructs a cDSA object to communicate with the remote DSACON32m controller within the SDH via TCP/IP (ethernet).

The connection is opened and established, and the sensor, controller and matrix info is queried from the remote DSACON32m controller. This initialization may take up to 9 seconds, since the DSACON32m controller needs > 8 seconds for "booting". If the SDH is already powered for some time then this will be much quicker.

Parameters

debug_level	- the level of debug messages to be printed: if > 0 (1,2,3...) then debug messages of cDSA itself are printed if > 1 (2,3,...) then debug messages of the low level communication interface object are printed too
_tcp_adr	: The tcp host address of the SDH. Either a numeric IP as string or a hostname
_tcp_port	: the tcp port number on the SDH to connect to
_timeout	: The timeout to use: <= 0 : wait forever (default) T : wait for T seconds

void cDSA::SetFramerate	(	UInt16	framerate,
		bool	do_RLE = true,
		bool	do_data_acquisition = true
	)

Set the framerate for querying full frames.

Parameters

framerate	- rate of frames.
do_RLE	- flag, if true then use RLE (run length encoding) for sending frames
do_data_acquisition	- flag, enable or disable data acquisition. Must be true if you want to get new frames

• Use framerate=0 and do_data_acquisition=false to make the remote DSACON32m in SDH stop sending frames
• Use framerate=0 and do_data_acquisition=true to read a single frame
• Use framerate>0 and do_data_acquisition=true to make the remote DSACON32m in SDH send frames at the highest possible rate (for now: 30 FPS (frames per second)).

void cDSA::SetFramerateRetries	(	UInt16	framerate,
		bool	do_RLE = true,
		bool	do_data_acquisition = true,
		unsigned int	retries = 0,
		bool	ignore_exceptions = false
	)

Set the framerate for querying full frames.

Parameters

framerate	- rate of frames. 0 will make the remote DSACON32m in SDH stop sending frames, any value > 0 will make the remote DSACON32m in SDH send frames at the highest possible rate (for now: 30 FPS (frames per second)).
do_RLE	- flag, if true then use RLE (run length encoding) for sending frames
do_data_acquisition	- flag, enable or disable data acquisition. Must be true if you want to get new frames
retries	- number of times the sending will be retried in case of an error (like timeout while waiting for response)
ignore_exceptions	- flag, if true then exceptions are ignored in case of error. After retries tries the function just returns even in case of an error

Definition at line 810 of file dsa.cpp.

void cDSA::SetMatrixSensitivity	(	int	matrix_no,
		double	sensitivity,
		bool	do_all_matrices = false,
		bool	do_reset = false,
		bool	do_persistent = false
	)

Send command to set matrix sensitivity to sensitivity as float 0.0 .. 1.0. If do_all_matrices is true then the sensitivity is set for all matrices. If do_reset is true then the sensitivity is reset to the factory default. If do_persistent is true then the sensitivity is saved persistently to configuration memory and will thus remain after the next power off/power on cycle and will become the new factory default value. If do_persistent is false (default) then the value will be reset to default on the next power off/power on cycle

Warning

PLEASE NOTE: the maximum write endurance of the configuration memory is about 100.000 times!

Raises a cDSAException in case of invalid responses from the remote DSACON32m controller.

Remarks

Setting the matrix sensitivity persistently is only possible if the DSACON32m firmware is R268 or above.

Definition at line 836 of file dsa.cpp.

void cDSA::SetMatrixThreshold	(	int	matrix_no,
		UInt16	threshold,
		bool	do_all_matrices = false,
		bool	do_reset = false,
		bool	do_persistent = false
	)

Send command to set matrix threshold to threshold as integer [0 .. 4095] (0 is minimum, 4095 is maximum threshold). If do_all_matrices is true then the threshold is set for all matrices. If do_reset is true then the threshold is reset to the factory default. If do_persistent is true then the threshold is saved persistently to configuration memory and will thus remain after the next power off/power on cycle and will become the new factory default value. If do_persistent is false (default) then the value will be reset to default on the next power off/power on cycle

Warning

PLEASE NOTE: the maximum write endurance of the configuration memory is about 100.000 times!

Raises a cDSAException in case of invalid responses from the remote DSACON32m controller.
