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.

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.

Destructur: clean up and delete dynamically allocated memory.

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

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

Send command to set matrix sensitivity to sensitivity as float [0.0 .. 1.0] (0.0 is minimum, 1.0 is maximum sensitivity). 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.
void cDSA::SetMatrixThreshold ( int  matrix_no,
UInt16  threshold,
bool  do_all_matrices = false,

) throw (cDSAException*, cSDHErrorCommunication*)

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.

Remarks:
