About this deal

It is licensed under the terms of the GNU GPL, version 3 or later. Design goals and features include: I looked at both this logic analyzer and the Usbee SX just last month, when I finally decided that my old Tektronix 1241 was no longer worth the electricity it burned, and even with GPIB couldn’t give me the flexibility I needed. wooddragon48 has updated components for the project titled 3D Printed Repeating Crossbow/Sling Shot Pistol. Logic analyzers take the guess work out of debugging inter-chip communication. If you can’t see what’s going on, the best you can do is guess about the problem. When a project won’t work, 99% of the time we can solve the problem immediately by looking at the signals with a logic analyzer. Without it, there’s no easy way to know what’s happening.

ericwertz – if you need to look at 50mhz digital data, then 100Mhz sampling is not nearly enough. Nyquist theory is meaningful for analog analysis, and is a limitation that applies directly to the highest frequency pure sine wave component of the signal – exclusive of phase. Digital analysis is very different. You could barely represent a square wave sampling at Nyquist, and thus would get virtually no timing information from the resulting waveforms. You’ll need to sample 4-10 times your bus rate to get meaningful timing information. fiddlingjunky said: “One thing to keep in mind is the RP2040/Pi Pico does have a hardware bug (slightly mis-specced internal capacitances) that create ~9LSB non-linearity (0.22% of measurement range) at 4 points.” There are Differential Non-Linearities [2] and Integral Non-Linearities [3] caused by mis-matching of on-die ADC capacitors. Reusable libraries. Consists of the libsigrok and libsigrokdecode shared libraries which can be used by various frontends/GUIs.

When it debuted, the Logic was so popular that it was hard to buy one. It’s now widely available, and Saleae gave us one to try. Read our review below. The sigrok project aims at creating a portable, cross-platform, Free/Libre/Open-Source signal analysis software suite that supports various device types (e.g. logic analyzers, oscilloscopes, and many more). Ian – re other products: I don’t want to post a commercial for anyone, so I won’t mention my favorite by brand name. Just do a google search for “logic analyzer”. There’s about a zillion products in this price range out there these days.

I just got my first logic analyzer from a family member for Christmas (as merely a hobbiest, I couldn’t afford dropping money on one for myself… I just don’t have quite enough need) this past year. I wasn’t involved in the decision-making process (thus the disadvantage of *not* buying for oneself), but the got me a USBee SX series — it’s very similar in form factor to this little baby, and I suspect is approximately similar in specifications. Works pretty well to help debug my PIC projects.Raspberry Pi confirms there is a hardware flaw in the RP2040 ADC. Refer to the RP2040 datasheet build-date: 2021-11-04, build-version: 150df05-clean, sections “4.9.3. ADC ENOB”, “4.9.4. INL and DNL”, and in-datasheet errata “RP2040-E11”.[1] Most modern electronics projects will benefit more from a logic analyzer than an oscilloscope. An oscilloscope displays a graph of an analog voltage as it varies over time, such as the curve of a sine wave. A logic analyzer only detects high and low digital states, but it records many signals simultaneously. Logic analyzers dump data to a computer for analysis, very few oscilloscopes have this feature. Broad hardware support. Supports many different devices (logic analyzers, oscilloscopes, multimeters, data loggers etc.) from various vendors. Now if I could only find a decent USB 2.0 oscilloscope. I think though, that that’s one realm where I still need a real device, perhaps with a decent USB transfer and control interface. 250MS/sec+, 2+ channels, 600V+ and decent triggering options (say an external trigger that I provide with the logic analyzer?) The Logic records 8 channels at 24MHz. The Windows software has useful features, and there’s an SDK if you want to write your own apps. Linux and Mac versions are under development. We really like this logic analyzer, and plan to use it to illustrate future articles.

Big DNL spikes caused by an apparent mismatch between capacitors used in simulation and production, James Adams confirms. We really like the profiles that decode most common serial protocols; 1-Wire, I2C, SPI, and asynchronous serial. CAN and other protocols will be added eventually.

We’ve covered Pulseview being used in combination with cheap accessible analyzers before — a must-watch if you need to get yourself up to speed on the value they provide to a hobbyist. If an oscilloscope is what you need and a smartphone is what you have, perhaps you’ll enjoy the Scoppy firmware for the Pico. We also tried the 1-Wire decoder with a DS2431 EEPROM. The software identified the 1-Wire reset command, and the 1-Wire ‘search rom’ command (0xf0).
