SICK LMS511 sensor data acquisition interface (source code, C++/MFC)

This is data acquisition source code of LMS511(SICK co.)

Source code is made by MFC(vs 2008).
The sensor is communicated by TCP/IP.
You can set sensor ip and test running by  sopas program.
The sopas program is included in the manual CD.



This movie is running test video.

CString to char *

- CString to char*

1. memcpy
CString str = "test";
unsigned char st[30];
memcpy(st, (unsigned char*)(LPCTSTR)str,str.GetLength());

2. strcpy
CString strData = "test";
int length = strData.GetLength();
char* st = new char[length];
strcpy(st, strData.GetBuffer(0));

3. Type convert
CString str;
str = "test";
char* st = LPSTR(LPCTSTR(str));

- char* to CString
Using Format function in CString class
char st[] = "test";
CString str;
str.Format("%s", st);
