Oscilloscope application for Arduino & .NET
Includes full source code
- Sample 2 analog channels
- Volt/Div = 0.1÷0.5V (input voltage 0÷5V)
- Time/Div = 1÷100msec (max. sampling rate 200µsec)
- Rising/Falling/Both trigger & level adjust
- Single/repetitive trigger
- Click & drag mouse on screen to measure
Had problem with flickering display (unless keying on it permanently) under XP and .NET 4 (no previous experience with this framework). However it works fine in a netbook under Windows 8. My Arduino is a clone from Seeedstudio. Great package, I needed something simple to test a sequencer. Congratulation.
good project scopino
Project is a simple 2 channel oscilloscope with trigger mode and windows GUI. Microcontroller part works on Arduino (I tested it on Arduino Pro Mini clone), uses 115200 virtual serial port baud rate. 0-5 V input signal is taken from A0 and A1 analog inputs. Controller part receives control commands from graphical interface part for setting time resolution, voltage scale, trigger level and other parameters. Number of samples is 500. Samples are send in packets via COM port or its USB emulation. GUI part requires "." decimal divider to be set in your windows regional settings.
