OsciPrime – Tablet Oscilloscope and Data Acquisition


OsciPrime is an Open Source high speed data acquisition hardware platform and Tablet 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

OsciPrime – Oscilloscope and 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.

Using USB, the hardware plugs into Tablets that support USB Host. Together with the OsciPrime oscilloscope application it turns a tablet or mobile phone into a high speed data acquisition system.
