An Alternative Oscilloscope: Overview Details Name: alternascope Created: 30-May-2005 12:15:59 Updated: 29-Oct-2005 00:12:21 CVS: browse Other project properties Category :: Other Language :: Verilog Phaze :: FPGA proven Development status :: Beta Project maintainers Stephen Pickett Statistics view Description AlternaScope provides a cheap alternative to expensive oscilloscopes; Using a VGA display and a simple mouse interface, a user can use this scope to look at and measure signals up to about 80Mhz. This kind of scope would be ideal for hobbyists and students looking to learn and debug circuits. Development is based on the Spartan III Starter Kit from Xilinx. The ADC is simply controlled by an MCU (another starter kit: the ATK500 from Atmel) but will soon be controlled by the FPGA (to achieve the faster speeds). In the future, schematics and PCB layout binaries will be available. NOTICE: I have started working on a 'BMP Picture' style of exporting data via RS-232 or USB, but do not have the time to write a Win-32 application to interpret the data. Anybody interested? I aplogize for the bad quality of the snapshot. This is why I need screenshot support :) Features Timescale selection Selectable trigger (Rising, Falling / Normal, Single, Auto) Horizontal and Vertical position offsets Grid Display On/Off/Outline Semi-standard Oscilloscope look and feel VGA display; drives a standard computer monitor PS/2 Mouse User Interface 9-bit input data width Developed specifically for the Spartan III devleopment kit from Xilinx (for now) Soon to come (Not necessarily in this order) FFT display Measurement Display (amplitude, frequency) Cursors Vectors Multi channel display (up to 8) Channel Math UART or USB computer communication (data export)
