Recently, I was debugging an OLED display, and I just couldn’t get it to communicate correctly, which was very frustrating. So, I casually searched on eBay for a logic analyzer, planning to buy a cheap one to use. The most common item on eBay was this one: 8 channels, 24MHz maximum sampling rate, priced around … Read more
Build a 100MHz Logic Analyzer with Raspberry Pi Pico Transform a Raspberry Pi Pico (or any RP2040 board) into a simple logic analyzer in just 5 minutes. Introduction A logic analyzer is an electronic instrument that captures and displays multiple signals from digital systems or circuits. It can convert captured data into timing diagrams, protocol … Read more
Concept of Logic Analysis The logic analyzer is also a very commonly used instrument, just like the oscilloscope, and is one of the classic instruments for digital design and measurement. When measuring digital circuits, when should an oscilloscope be used? Generally, an oscilloscope can be used when precise parameter information (such as time intervals and … Read more
A logic analyzer is an instrument used to simultaneously capture, display, and measure multiple electronic signals in digital circuits. Logic analyzers can show the relationships and timing between many different signals in digital systems and are often capable of analyzing digital communication protocols such as I2C, SPI, and serial. Therefore, logic analyzers are the best … Read more
Tip：Click the above↑ to quickly follow this account For a long time, the logic analyzer has been shrouded in mystery. While most R&D personnel are very familiar with oscilloscopes, they may still be somewhat unfamiliar with logic analyzers. You might guess that it is an expensive, large instrument with a bulky chassis. Right or wrong, … Read more
Click the blue text above to follow us The logic analyzer is an instrument that collects and displays digital signals from the test device using a clock, primarily for timing judgment. Unlike oscilloscopes, which have multiple voltage levels, logic analyzers typically display only two voltages (logic 1 and 0). After setting a reference voltage, the … Read more

In a previous article, we introduced a logic analyzer built using a serial port. Today, we will discuss a logic analyzer based on USB2.0+FPGA. Before we begin, let’s introduce a logic analyzer’s host software – sigrok. Without good host software, even if the hardware is built, the experience will not be good. sigrok Here is … Read more
