Welcome on my Homepage.
I started a project to build a USB-oscilloscope to learn more about (analog) electronics. The project will be as OpenSource as possible. Unfortunately some tools I use to build the project are only available as closed source (more of this below), but all the stuff I create will be fully open source.
The project is currently in a very early state so don't expect too much. It is still far away from a “real” oscilloscope. The whole analog frontend is missing, there is no triggering and I can't tell you how accurate the measurements are (probably not at all). What it currently does is displaying a waveform of a measured voltage on the computer. The input can be between 0V and 3.3V. The sampling rate is around 20k samples per second.
On the left you can see a screenshot from the GUI Application that displays a measured waveform. The values on the time axis do not correspond to any real values in seconds (they just count the samples). In the following I will describe what I did so far. For the details have a look at the source code and schematics provided below.
