K8055 - multiple cards - switching time (SetCurrentDevice)

Hello,

We are working on a project that may need multiple boards:
K8055 USB Experiment Interface Board - P8055-1 @ Velleman 2003.

I’d just like to ask, what is the timing overhead in a call to SetCurrentDevice ?
We’ve got the newest DLL to control 1-4 devices.

The call to “SetCurrentDevice” does not have any timing overhead.
Only the calls to the functions to write or to read from the car have some timing overhead.

The delay can be 2ms to 10ms depending on the operating system and platform.
In this thread you’ll see some test results:
