description:
The user does not have to care about the complicated USB bus protocol, but can directly work with USB2.0 bus. USB2sdll is merged into the development environment and the user can access his hardware using the functions of USB2sdll.
The Software of the interface module is written automatically by USB2sdll to the controller, so that the newest update of the software is always installed in the interface module (hardware).
You can start developing usb2.0 hardware at now!

Functions of the DLL:
SetCallBack
SetDefaultGpifParams
StartStream
StopStream
SetLicense
StreamActive
LostPacketCount
StreamDevPresent
SetGpifParams
SetGpifParamsFromFile
SetSlaveFifoParams
SetPortDir
SetPortState
GetPortState
I2cTransfer
SpiTransfer
