UsbSetup Procedure |
Version 7 |
Sets the specified USB device characteristics.
[ lStatus = ] UsbSetup (hDevice, bUSBTMC, lInterfaceNumber, lConfigurationIndex )
The UsbSetup procedure syntax has the following parts:
|
Name |
Type |
Description |
|
lStatus |
Long |
Status: -1 = error, 0 = success |
|
hDevice |
Val AHandle |
Handle to the USB device |
|
bUSBTMC |
[Val] Bool |
True=USBTMC mode (default), False=RAW mode |
|
lInterfaceNumber |
[Val] Long |
Current Interface Number (Default=-1) |
|
lConfigurationIndex |
[Val] Long |
Current Configuration Index (Default=-1) |
By default, UsbOpen will select the first configuration and interface to be used as default in RAW mode. UsbSetup is used to select a new mode, configuration, or interface.
When bUSBTMC=True, ATEasy will automatically select the interface and configuration which support USBTMC mode, and lInterfaceNumber and lConfiguration are ignored.
The following example selects USBTMC mode:
UsbSetup(hDevice, True)
