Help me two questions about microcontroller communicating with Labview

[sonicvn]

The first,sorry for my bad English.

I have 2 following questions:

    1.How to know the max baudrate in Labview when we use microcontroller communicating with Labview,how much the max baudrate in Labview is for not losting data.

    2.How to create a buffer in Labview when we send data from microcontroller,the data will be saved in this buffer,and we can access this data anytime?

I use VISA Read,VISA Write for communicating microcontroller with Labview.In VISA Read,Write,the transmitting or receiving data will be saved in read buffer or write buffer.And what is the size of read buffer or write buffer?

I'm waiting the answers from everyone.

Thank you very much!!!

Max baudrate will be affected by the hardware VISA is using to interface to the uP and how the LabView code is structured.   You should be able to make it run pretty fast.

Use the "VISA Set I/O Buffer Size.vi" to control the buffer size.  Otherwise you are at the mercy of VISA and the operating system.
