BitScope Software for Raspberry Pi Oscilloscope
The most frequently asked question since we created this blog is what software can I use?
The short answer is you can run all the software we offer for x86 based Linux including DSO, Logic, Chart, Meter and Library on Raspberry Pi.
The long answer is that while the DSO, Meter and Library work well, especially if you don't try to drive the graphics too hard, the others are not quite there yet.
This mostly comes down to the Raspberry Pi's non-accelerated graphics at the moment. For the library (which has no graphics) it runs almost as fast as it does on x86. For apps with simple graphics (like Meter) it's slower but quite usable. For apps with sophisticated graphics (like DSO) you may need to avoid using some of its digital phosphor and spectrum analysis modes if you want a quicker display refresh rate but using BitScope to capture one-shot analog and logic waveforms and for slower speed repeating updates it works very well.
Like everyone else we're following Raspberry Pi Foundation's work getting Weston running native Wayland apps on the Pi. We're certain that when the Pi's native graphics acceleration is unleashed amazing things will be possible with real-time waveform display and data analysis.
Of course off-the-shelf graphical apps for BitScope on Raspberry Pi are only part of the story. We ported this software to Raspberry Pi to prove BitScope can work well with a low power embedded ARM system. However, as an embedded server the Pi also excels so in a future post we'll outline how to program your own software for BitScope on Raspberry Pi for server based local and network connected test, measurement and data acquisition.
