We demonstrated that one Raspberry Pi B+ can happily power and run up to four BitScopes without problems !
We're very impressed with Raspberry Pi B+.
We love the form-factor, mounting holes, Micro-SD card and 4 x USB. It's an excellent evolutionary step for Raspberry Pi and a very useful one for BitScope!
We've tested BitScope Micro and BS10 in all sorts of combinations. All of them work brilliantly. Pictured here is a pair of BS05 and BS10 where one of the BS10 units is also powering an electronics circuit.
The Raspberry Pi B+ is running four instances of BitScope DSO where each instance is talking to its own BitScope. We've pulled a little trick to do this; B+ has four USB ports so we had to disconnect the keyboard/mouse to connect the fourth BitScope.
The point is that we proved that four BitScopes can be used with one Raspberry Pi B+. In fact, accessed via a network, either using X or VNC or BitScope Server, you can create a remote mixed signal test and measurement system within minutes.
For example, four BS10U provides access to 8 analog and 32 logic channels and 4 waveform generator outputs via one Raspberry Pi B+. All you need is a LAN connection and 5V USB power supply.
We're very excited by the opportunities opened up by Rasberry Pi B+. It turns out that BitScope Micro and BS10 are both sufficiently low power that the default power budget of Raspberry Pi B+ running on a bog standard USB power adapter is more than enough. However B+ has a "high current" USB setting which allows up to 1.2A aggregate over the 4 USB ports so we could power a lot more from this little guy. Of couse you need a high quality 2A supply for the Pi!
It's been a while since the last blog post but we've been very busy working on several exciting new projects for BitScope Micro and BS10. We'll be posting more soon and the new Raspberry Pi B+ will be centre stage. Stay tuned!
