Current projects

Finished projects

  • 2008 - Develop a digital osciloscope with two coleagues of mine. The osciloscope is connected to the computer via a ISA Card. The interface software is written in Lazarus and is a Multi-platform, graphical application that can access the ISA Card on both Windows and Linux. You can download the final report and also the source code for the software here: http://eletronicalivre.incubadora.fapesp.br/portal/english/oscilloscope/
