RS-485 is a commonly used differential communication bus, capable of long-distance transmission with good interference resistance. However, how can we monitor the communication process for several hours or even days in the face of occasional faults during communication? 1. Testing Requirements Low-cost long-term monitoring of RS-485 bus communication. 2. Testing Challenges The RS-485 is … Read more
Logic Analyzer is an instrument that analyzes the logical timing of digital signals, capable of precisely capturing and displaying multiple digital signals, providing signal timing, protocol analysis, and other functions. It is also one of the most commonly used tools for embedded engineers in daily development. Now, we can use the Haozhe RP2040 development board … Read more
Previously, we introduced how to create 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 is based on FPGA + USB PHY. The combination of the advantages of FPGA and the high accessibility of USB has kept it in … Read more
Abstract Are you still calculating repeatedly to locate errors, struggling to choose triggers, and worrying about reducing sampling accuracy? When debugging signals, we always hope that the storage time of the logic analyzer can be as long as possible. So, how can we maximize the storage time of the logic analyzer? 1. Increase Memory Space … Read more
Whether you are developing microcontrollers or FPGAs, a protocol analysis tool – the logic analyzer, is often used. Unlike oscilloscopes, it can only collect digital signals, with sampling rates typically ranging from hundreds of MHz to GHz, supporting multiple channels for simultaneous sampling. The accompanying software supports parsing dozens of protocols such as I2C, UART, … Read more
Content Summary Previously, we released a high-performance logic analyzer with 8 channels and a 500M sampling rate based on the BX71 core board. Many users of the ACZ702 development board also hope we can provide firmware based on the ACZ702 development board. Today, we bring you this high-performance logic analyzer firmware and usage instructions based … Read more

A Dual-Shoulder Backpack How Difficult Is It? Give It a Try! →_→ Long Press Recognition Circuits synthesized from FPGA are located inside the chip, making it nearly impossible to measure signals using oscilloscopes or logic analyzers. Therefore, manufacturers like Xilinx have invented built-in logic analyzers. In Vivado, this is called ILA (Integrated Logic Analyzer), whereas … Read more
