Thanks to both replies. I could not do any further testing yet since my job responsabilities involve more than coding.

rnixon, I will install and test with wireshark. I'll pay attention to the flags and see what is going on.

tod, I had no idea of the gist website! I'll look to register there so I ...

Hi rnixon,

We write our own PC software and NB firmware. They comunicate with each other over TCP and serial. When the Software application starts, it sends a "hello" message and when it exits, a "goodbye" message. A handshaking scheme we came up with. We are monitoring the messaging with a ...

Hi rnixon,

Thanks for the reply.

"The max of 32 is located in the network programmers guide" Thanks!!! It also says 38-63 are available for expansion. How do I access those? Is there a way to monitor how many sockets are open?

"Note that any listening sockets do consume a socket, such as the web ...

Hi,

I have a list of 10 sockets to possibly open, my application only utilizes 6 out of the 10.
The PC sends commands to the NetBurner to open the sockets, to listen on a port. The sockets are opened, one by one, and assigned to specific port numbers.

The 10 sockets have their file descriptors ...

Paul,

float float_speed;
OSQPost( &QueueIRQ3, (void *)float_speed);

never worked for me. I was experimenting with ints. Then, when I tried the float, I got the compile error.
"invalid cast from type 'float' to type 'void*"

Tod and Larry pointed out that this would not work as is, that I had to ...

Paul,

That's how I started the float discussion. Please see my post from "Fri Jul 23, 2010 6:42 am"

Tod, thanks for the reply. I'm not a C++ programmer, but I was reading a little about static variables, and knew what they mean inside a class. I don't have that section of code implemented with classes, so I think the simplest way (without resorting to "pigs") would be to declare a static float ...

Thanks all for the replies.

So I guess putting the float into a queue is not good practice; specially after seeing the warnings and workarounds to do so.

So what would be the proper method of doing this?

Hi Tod and Paul, thanks for the replies.

I got it to work, except for one case where I want to queue a float:

float float_speed;
OSQPost( &QueueIRQ3, (void *)float_speed);

I get this error: invalid cast from type 'float' to type 'void*'

Why is this? isn't a float represented as a 32-bit value ...

Hi Paul,

Thanks for the reply.

"You don't pass the pointer.(You are correct it can go out of scope)"

I'm actually posting the value of i ?

Example:
- int i is a local variable let's say at address 100 .
- assign i = 5
- OSQPost(&myQ, (void * i));
I'm storing 5 into the queue?

Where can i go ...
