Serial Oscilloscope is a Windows application that plots comma-separated variables within any incoming serial steam as channels on a real-time oscilloscope. The application also functions as a basic serial terminal, received bytes are printed to the terminal and typed characters are transmitted. The project uses Michael Bernstein's oscilloscope library to plot up to 9 channels on 3 different oscilloscope with view and trigger menus.
Serial Oscilloscope is compatible with any serial stream containing comma-separated values terminated by a new-line character ("\r"). For example, "11,22,33\r" will be interpreted as values 11, 22 and 33 for channels 1, 2 and 3 respectively. The serial stream can also include non numerical characters which will be ignored. For example, "a=0.5,blue,x=3.14,t1t2t3,8\r\n" will be interpreted as values 0.5, 3.14, 123 and 8 for channels 1, 2, 3 and 4 respectively.
The source files also include an Arduino sketch to send analogue input values over serial. Up to 6 ADC channels can be enabled by sending the characters "1" to "6" to the Arduino. Enabling more channels will reduce the sample rate.
Precompiled binary files can be downloaded from the x-io website.
