Saleae Logic16 - 16-Channel USB Logic Analyzer Review
Saleae Logic16 is a 16 channel logic analyzer. You use a logic analyzer to monitor the signals between microcontrollers and other parts of an embedded system. The Saleae Logic16 samples at up to 100MHz, can record billions of samples, and automatically decodes the SPI, I2C, Serial, CAN, 1-Wire, I2S, PCB, UNI/O, and Manchester protocols.

Saleae Logic16 - 16-Channel USB Logic Analyzer Feature
- Flexible sample rate Sample 2 channels at 100MHz, 4 channels at 50MHz, 8 channels at 25MHz, or all 16 channels at 12.5MHz.
- 16 channels As you might have guessed from the name, Logic16 lets you connect up to 16 of your most troublesome signals
- Comes complete Logic16 includes everything you need: x2 ultra-flexible 1x9 22AWG 64/40 wire harnesses, 18 high-quality micro-hook probes, a USB cable (2 meter mini-B to A), and a nice carrying case.
- Billions of samples Logic16 can save as many as 10B samples, letting you capture even the most elusive events. No more dealing with frustratingly small sample buffers.

Fantastic
By Adam Reynolds
I can't believe there isn't a review of this device here yet. What can I say? It's small, easy to carry, very easy to use, and powerful. I won't bore you with the sample rates, etc., since you can find all of that information on their site. I'll simply say that the device, and the software to control and use it, are both very easy to use, and so far have been rock solid in regards to stability and consistency. It's also cross-platform, working great on Windows, Mac, and Linux (don't worry about the "Ubuntu" title on the download page, it works fine with OpenSUSE, Fedora, etc.).
In my first test, I simply attached it to the Tx pin on a UART serial port (1.8v TTL), set the software to trigger on a falling edge, and started acquisition. I then went to the machine controlling the serial port (a gumstix overo), and dumped a message out over serial (just a regular old sentence). The Logic16 triggered on the signal, grabbed it to completion, and when acquisition was done it displayed the waveform on the screen. I set up an async serial analyzer, matched up the bit rate, parity, etc with what I had configured on the gumstix, and the Logic software popped up with the ASCII letters corresponding to each character in the waveform, spelling out the exact sentence I had sent out on the serial port.
A simple test I know, but it worked flawlessly and was surprisingly easy to configure. I spent hours working with the Logic16 after that, and not once did the device or the software controlling it give so much as a hiccup.
This is not your run of the mill digital sampler which after 2 hours of setup will capture a waveform and then leave you to figure things out yourself. This truly is an easy to use logic analyzer, in a very small and portable package.

How did I ever live without this?
By John L. Sloan
For years I've made an excellent living doing embedded development close to bare metal. I've owned and used the original eight-channel Logic ever since it was first introduced, in my own work as well as in paying gigs for clients. I recently purchased and started using the sixteen-channel Logic16. These devices are so ridiculously functional for the price that if you buy one it will likely pay for itself the first time you use it. I'm not kidding. I've used the Logic to debug and reverse engineer issues with I2C, SPI, serial, GPIO, interrupts, pretty much anything on slow to medium speed logic signals and I/O busses (and written about it in my blog under the pen name Chip Overclock). You need to understand what your time is worth, and using devices like these will save you time and money.

Wow. why did I wait so long?
By Jesse
Totally saved my butt, and accelerated my development. Showed me things about the running of my circuit in moments that would have taken soooo much longer using my O-scope. 16 channels at once is extremely nice, and without the techtronics or HP price tag.
