ARM Based Handy and Portable Oscilloscope Using Graphical Display

摘要

The need to have a visual perception of signals in order to monitor events in time and value brought about the development of a measuring instrument referred to as oscilloscope. This is a design of handy and low cost oscilloscope. The user can start/stop the display, adjust the time division and adjust the voltage division. The requirements of the oscilloscope were three-fold: 1) low cost design, 2) capture frequencies at the medium range and 3) construct able with a basic skill of PCB designing.
