Existing application will not work with the new STU 430/530 pad
The STU 430 and 530 are not supported by older releases of our SDKs.
Support for these models was introduced with version 2.1.1 of the STU SDK (issued 01/11/2013) and version 1.11.2 of the Signature SDK, issued 23/10/2013.
Release branch 1 of the STU SDK (also known as the Vinae SDK) used a DLL called STUTablet.dll and a different API from the current STU SDK.
If you have this older release branch you will also need to rework any existing application code using the current STU samples as a guide.
Please download the latest release of the appropriate SDK and samples to ensure compatibility.
The SDKs are now available for download at any time from the Resources section on our Developer Relations Web Site
