Subject: Another Strange Problem...
I have several places in my controller where I run small DSP programs, but they don't always seem to run reliably. The DSP code itself runs perfectly with KMotionCNC. I'm running them with code like this:

String s = KMController.CompileAndLoadCoff(3, @"C:\My KFlop C Programs\Common\NewHome.c", false);
if (s.Equals(""))
KMController.WriteLine("Execute3");
else
MessageBox.Show(s, "Home.C Compile/Load Failed!");

Should I have something more than that? This particular example is a simple home routine, but it consistently gets to the point where the axis should start moving:

MoveRelAtVel(2, 20000, 10000);
while (ReadBit(HOME_LIMIT))
{
if (CheckDone(AXIS_Z))
{
Jog(AXIS_Z, 0);
printf("DoProbe failed\n");
return -1;
}
}

But the Z axis never moves, so it just hangs in the while loop. The axis is configured and enabled, and works fine running G-code.

I wonder if this may be related to the MainPathRoot issue and not properly finding the TCC67?

Brad,

But it is compiling, loading and running the program. It just appears the program does not run correctly. I get the printfs that precede that first move, but the move never happens, and I have a printf at the line immediately before the MoveRelAtVel, which shows me the arguments to the MoveRelAtVel, and they are correct.

Hello Ray,

 

You are running your init program first?

But it is compiling, loading and running the program. It just appears the program does not run correctly. I get the printfs that precede that first move, but the move never happens, and I have a printf at the line immediately before the MoveRelAtVel, which shows me the arguments to the MoveRelAtVel, and they are correct.

Hi Ray,
 
I can't really think of anything.  Possibilities might be that you have a bug somewhere else that is corrupting something.  Or possibly the download of the C program is somehow getting corrupted.  If somebody isn't playing by the rules and respecting the Token then commands/data can get intermixed and so forth.  But that type of thing usually results in an error of some sort.

TK

Ray,
 
The WriteLineReadLine and LoadCoff routines all handle waiting for the Token and releasing the Token internally.  The only responsibility an Application has is in rare cases where it is issuing a command that needs to send multiple lines of connsecutive commands/data or receive multiple lines of data.  So for example to upload a block of Gather Buffer data might require 4 calls of WriteLine, ReadLine, ReadLine, Readline.  In this case you are required to get the Token at the beginning and release it at the end otherwise you might get pre-empted in the middle and some other process or thread might issue a command/response and end up receiving the wrong data.
 
GetStatus falls into this catagory.  But I believe it is Waiting for the Token properly and if it doesn't obtain it it doesn't perform the operation.
 
Again I'm just grasping at straws on what your problem might be...
 
Regards
TK

You can use a global variable as a flag to signal that a thread has completed a task. If you're running on the KFlop itself, you can use the persist data structure (an array of integers).
