Hi! I'm trying to use the opencv bindings of Python. I tried the following code: [CODE]from opencv.highgui import * from opencv.cv import * cam = 'cam' cvNamedWindow(cam) cap = cvCreateCameraCapture(0) while cvWaitKey(1) != 27: img=cvQueryFrame(cap) cvShowImage(cam,img)[/CODE] Although the window seems to open fine, I cannot see any image. I just …

Hi! I'm having a similar program. Here is the code I am using - [CODE]#define DATA 0x378 void strober() { int c; if (ioperm(DATA,3,1)) fprintf(stderr,"You need to be root!\n"); for (c=0; c<50; c++){ fprintf(stdout,"LED should turn on.\n"); fflush(stdout); outb(0x07,DATA); sleep(t); fprintf(stdout,"LED should turn off.\n"); fflush(stdout); outb(0x00,DATA); sleep(t); } } int …

Hi! I'm trying to use the nanosleep and sleep functions in a program I am trying to write. I first tried this - [CODE] fprintf(stdout,"Hey guys.."); struct timespec t_req, t_rem; t_req.tv_sec = 1; t_req.tv_nsec = 500; if (nanosleep(&t_req, &t_rem) < 0) return 0; fprintf(stdout,"...What's up?");[/CODE] Since the function nanosleep did …

Hi Uday, A good practice is to google/bing/<search engine of your choice> for your request first. Quite often, you would find what you are looking for.

Hi! My problems are more of porting a code to Windows, than the code itself. I need to download a file from a URL ( http://127.0.0.1/img.jpg ) and store it in a local file. I think I've screwed up the setting up of the libcurl libraries. I am using Visual …

Well, the following should do the trick: [CODE]def func(x): y = (2*x*x*x) - (8*x*x) + x + 16 return y[/CODE] The best I can think of is a function that scans across the region of interest, maybe calculating f(x) for every 0.01 on the x axis. You can increase this …

Hi! I'm trying to build a Python extension with C/C++. I'm following the steps given in the documentation [URL="http://docs.python.org/extending/extending.html"]here[/URL].
