Driver version
This register holds information about the currently installed driver library. As the drivers are permanently improved and maintained and new
features are added user programs that rely on a new feature are requested to check the driver version whether this feature is installed.
The resulting 32 bit value for the driver version consists of the three version number parts shown in the table below:
Kernel Driver version
This register informs about the actually used kernel driver. Windows users can also get this information from the device manager. Please refer
to the „Driver Installation“ chapter. On Linux systems this information is also shown in the kernel message log at driver start time.
The resulting 32 bit value for the driver version consists of the three version number parts shown in the table below:
The following example demonstrates how to read out the kernel and library version and how to print them.
This small program will generate an output like this:
Reset
Every Spectrum card can be reset by software. Concerning the hardware, this reset is the same as the power-on reset when starting the host
computer. In addition to the power-on reset, the reset command also brings all internal driver settings to a defined default state. A software
reset is automatically performed, when the driver is first loaded after starting the host system.
It is recommended, that every custom written program performs a software reset first, to be sure that the
driver is in a defined state independent from possible previous setting.
Performing a board reset can be easily done by the related board command mentioned in the following table.

A software and hardware reset is done for the board. All settings are set to the default values. The data in the board’s
on-board memory will be no longer valid. Any output signals like trigger or clock output will be disabled.
