• How to check if can device is busy to write or read

  Hi, I'm using NI USB 8472 low speed CAN and I want to check if the device is used.

  because if I send a frame to the device CAN I have a continuous loop, sending another frame and I want to know who I'm not write or read my continuous loop at the same time.

  This loop is made with an asynctimer.

  How can I check if the device is used to prevent writing or reading at the same time?

  Kind regards

  If you choose to use the CVI locking mechanism or the methods of the critical Section of the SDK, the net effect is exactly: a single function that is used by all parts of your program to access a resource atomically. You needn't semaphores here. For example:

  Critical_section cs;         Declare in a scope that includes all threads wanting to use the resource

  void Init (void) {}

  ...

  InitialiseCriticalSection (&cs);)    Do this somewhere soon, before you actually use

  ...

  }

  void CommFunc (...) {/ / This function represents the resource that are not accessible at the same time}

  EnterCriticalSection (&cs);) Stop another thread to run past here

  ... / / Now this block of code can run without fear to be readmitted

  LeaveCriticalSection (&cs);) Finished - let other threads are using the same code

  }

  My main programming in real time, I tend to use the components of the SDK, as described above. Roberto promotes the CVI ones - I think that in this case, their operation is identical.

  Hi in my FMClient I the following method to check if the API is alive: bool::IsConnected() {return F_ApiAlive() > 0 ;} FMClient Once I connect to FM with F_ApiStartUp the IsConnected method returns true. However, if the user closes the application FM then continue this method always returns true. How can I check if the FM application is alive and the FMClient is connected with it? Should I run and test an API call? for example try to get active in the current document, or something else?

  Yes, the single thread is the normal state. There could be some tricks around it, however. You need to ask someone with the expertise of programming a little more. I would like to ask the question here:

• Error when you try to burn a CD: Windows Media Player cannot burn the files. If the burner is busy, wait until the current task is complete. If necessary, check that the burner is connected properly and that you have installed the latest device driver

  Windows Media Player cannot burn the files. If the burner is busy, wait until the current task is complete. If necessary, check that the burner is connected properly and that you have installed the latest device driver. ???

  I just burn a CD with no problem at all.  Using the same type of CD, brand new, I tried to burn another CD and got this error message:

  Windows Media Player cannot burn the files. If the burner is busy, wait until the current task is complete. If necessary, check that the burner is connected properly and that you have installed the latest device driver.

  I close all programs running, restarted my computer, changed on the devices tab, the speed of burning... everything I know to do and all the things I've read in these forums, no luck... still get the exact same message.  No idea why my CD-writer has decided to stop working for me?
