OsciPrime is an Open Source Android high speed data acquisition hardware platform andAndroid oscilloscope application

Using USB, the hardware plugs into Android devices that support USB Host. Together with the OsciPrime Android oscilloscope application it turns a tablet or mobile phone into a high speed data acquisition system.The OsciPrime Android software demonstrates how to work with high data throughput and shows how to favour the Java Native Interface for sample processing. The OsciPrime Android application can be easily extended with custom features.

The hardware consists of two parts: theanalogue front-end where a signal is tapped and adjusted for the A/D conerters and adigital front-end where the data is quantified and prepared for USB transmission. Key components are a Xilinx Coolrunner CPLDand a Cypress FX2 microcontroller.
