Embedded Development: Mastering the Logic Analyzer
Microcontroller development engineers and electronics enthusiasts deal with various digital circuits daily. In addition to using multimeters and oscilloscopes for circuit debugging, a logic analyzer is also essential. A logic analyzer is an instrument that collects and displays digital signals from a test device using a clock, primarily for timing analysis. Unlike oscilloscopes, a logic … Read more
The Highlights of a 17 Yuan Logic Analyzer Revealed After Disassembly
I have seen these very cheap logic analyzers for sale for a long time,17 yuan, and it comes with a USB cable and Dupont wires. I was curious about how they managed to do this, so I bought a set to disassemble. There are10 pin headers, with a total of8 channels, plus one CLK and … Read more
Disassembly of a 17 Yuan Logic Analyzer: Is the Cypress Chip More Expensive than the Whole Unit?
I saw this very cheap logic analyzer for sale a long time ago,17 yuan, and it even comes with a USB cable and Dupont wires. Out of curiosity about how it was made, I bought a set to disassemble. 10 pin headers, with a total of 8 channels, plus one CLK and GND signal. It … Read more

Handcrafted OS Transformation Benchmark Code – Simple Scheduling Algorithm (Part 2)
This article will rewrite the handcrafted OS – a function running the minimum core code of FREERTOS, as shown in the figure below. Mainly: rewriting vTaskSwitchContext + background tick interrupt automatically switches tasks. In fact, the functionality has been completed in two articles, but it seems clumsy to represent using UART. This article aims to … Read more
Building a Logic Analyzer with FPGA
Previously, we introduced how to make a logic analyzer and oscilloscope using RP2040. Today, we will build a logic analyzer using FPGA. Currently, the mainstream architecture of logic analyzers in China uses FPGA + USB PHY. The combination of the advantages of FPGA and the high accessibility of USB has allowed it to occupy the … Read more
How to Simulate STM32 Microcontroller in Keil
1. Introduction When learning about the 51 microcontroller, we often use the combination of Keil and Proteus for experiments. This simulation saves us a lot of hardware and time costs, allowing us to visually observe the execution process of the code. However, when switching to the STM32 series microcontrollers, Proteus is obviously not supported, but … Read more
