Greetings,
I am stuck on a topic for TAFE and cannot get my head around it.
I need to Write a program to use a D to A converter board to output various signals which can be viewed on an oscilloscope.
I have made the Triangle wave, which works, but am stuck on the sine wave.
Code for sine wave thus far is:
int val;
int DCBias = 128;
int steps = 128;
int lp;
double dg = 3.141592654 / (steps/2);
val = sin(lp * dg) * 127 + DCBias;
for (lp = 0; lp <= 128; lp ++)
{ outp (DataPort,val);
delay (20);
}
printf("Press any key to exit Sine Wave output\n");
while (!kbhit()) break();
It will not compile and I keep getting errors. I think the problem lies within the last line of while the keyboard is hit, perform a break.
Thanks in advance for any help.

'break' is not a function and you don't even want to break out of that loop as long
as there is no key hit yet. Also, I think that the same signal value is sent to that
device for 129 times.
kind regards,
Jos

I need to handle signals to close some excel applications that my
script open, when the script is killed by another process.
My script is a little bit complex, but I wrote just two very small
scripts to test the kill and signal.
The scripts signal.pl is this one:
map {$SIG{$_} = sub {my $n = shift; print "n=$n\n"}} keys %SIG;

Hi,
I am writing an application in C++ on Linux, using threads (this is
my first experience with pthreads). The application itself is fine, it
is just that I wanted to handle asynchronous signals correctly, in
particular the SIGINT, preventing the application from stopping
ungracefully.
Indeed, I'd like to catch the signal, close everything in a
consistent way and stop the application.

Hello,
I am looking for material that describes how *precisely* UNIX-based
signals interact with the normal C++ execution flow of control and
guidelines on how to treat signals in an "object-oriented style".
So far I have not been able to locate much on the subject. Can anyone
provide any pointer/information or suggestion?
Thanks, max

Hi everyone,
I'd like to know when and how signals are used (e.g. SIGFPE, SIGABRT,
SIGTERM, SIGSEGV, SIGINT)? Thank you so much.

Hello all.
I've got a bunch of existing, non managed, C++ DLLs that export types
with, among other things, public events implemented using the
boost::signals library.
Now, I need to have these DLL interoperate with managed code. Among
others things, the managed code need to be able to register for
notification with the boost signals. I've tried different approaches
(trying to register a pinned delegate with the boost::signal, etc...),

Dear All,
I have some a program in which I link a static library. The static
library has a initialize() and uninitialized() function.
Now when I call the initialize function a thread is being started up
and it makes use of the linux timer and start sending signals in a
certain frequency. This is a problem as when I use the getch()
function I see that something is being written continuously to the
console, which is not a satisfactory...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.

For most users, this new feature is actually very convenient. If you want to control the update process,...
