For novel ideas about building embedded systems (both hardware and firmware), join the 27,000 engineers who subscribe to The Embedded Muse, a free biweekly newsletter. It takes just a few seconds (just enter your email, which is shared with absolutely no one) to subscribe. Embedded developers - both those doing hardware work and those crafting firmware - use a wide range of tools, but it can be awfully hard to distinguish the good from the ugly.

Philip Freidin sent a very comprehensive chart of USB instruments, which is here .
It's hard to put a "time-saved" number on it as things suddenly jump out at you instantly when you can see the decoded bus in real time!
In particular, I find the time and voltage scales that are displayed on the edges of the graph to be very useful.It is a small, inexpensive, 8-channel device that can capture and continuously stream data with sample rates up to 24MHz to your Windows/Mac/Linux machine for display and analysis.Martin Thompson also likes , and said: And when you consider that the software decodes UART, SPI, I2C straight onto the waveform display (as overlays), it's a must have for low-speed serial bus debugging.I purchased it shortly after it was released, on the _promise_ that they'd soon have a Mac and Linux client.It took longer than I liked, since I had to run it in a VMWare virtual machine on my Mac, but eventually they released a cross-platform software package. Finally an embedded tools vendor that understands there's other operating systems out there than Windows.
