Notice: This page contains information for the legacy Phidget21 Library. Phidget21 does not support VINT Phidgets, and will not support any new Phidgets. Phidget21 will be maintained until 2020. We recommend that new projects be developed against the Phidget22 Library.
- Make sure your libraries are properly linked
- Go from source code to a test application as quickly as possible
- Ensure your Phidget is hooked up properly
