the TI USB Serial Adapter API and USB to GPIO adapter

Hi Champs,

Our customer is use TI USB serial adapter API and USB to GPIO adapter to design their own GUI.

However, they got some problem when the process call is implementing .

The condition is as bellowing:

As we usually did before, we open two or more instance(GUI, C# window form) same time,

  1. If we do not invoke any “process call” function, all these window GUI instances are all working properly.
  2. But, when any one window GUI invoke a “process call”, then other window GUI’s operation is halted,the GUI is totally “dead”(even mouse click not responded) until close the GUI that invoked the “process call”.
  3. The invoked “process call” GUI itself functional OK all the time, seems like only exclusive other pmbus GUI’s operation.

 This problem affect our debugging experience when we need two or more GUI operating in the same time.Did this “SMBusAdapter”(unlike “TIBusAdapters”) need an exclusive use of SAA adapter? How to recover other GUI’s use of the same SAA adapter?

Is it possible to solve ??

Thanks 

BR
