OsciPrime - Android Oscilloscope and Data Acquisition

OsciPrime is an Open Source Android high speed data acquisition hardware platform and Android oscilloscope application. All layers of the project - from hardware, to firmware, up to software - are well documented in great detail.

 Measure: Voltage, Freq, Time - and also - Run/Stop data acquisition

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