Hi All,
I am controling several SPI-to-USB adapters via Labview. Each device can be detected through serial number and then a handle is grabed, this handle (an integer number, say 0 or 1, etc) will be used for the following steps. However, it seems that sometimes different devices have the same handle number. But amazingly, as long as I keep the handle open, it will always control the corresponding device until I close the handle. I am wondering how exactly the Labview use the same handle numbers to control different devices? Many thanks!
