Build a 100MHz Logic Analyzer with Raspberry Pi Pico Transform a Raspberry Pi Pico (or any RP2040 board) into a simple logic analyzer in 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 decoding, … Read more
The logic analyzer has always been shrouded in mystery. While most R&D personnel are very familiar with oscilloscopes, they may still be somewhat unfamiliar with logic analyzers. Perhaps you guessed it is an expensive, large instrument with a bulky chassis. Whether right or wrong, at least that’s what I thought when I was in college. … Read more
SPIDriver is an easy-to-use tool for controlling SPI devices, compatible with Windows, Mac, and Linux systems. It features a built-in color screen that can display all SPI communications in real-time, using a standard FTDI USB serial chip to communicate with the PC, eliminating the need for special drivers. The SPIDriver evaluation board includes 3.3 V … Read more
We currently have standard techniques for generating negative output voltages and methods for dynamically adjusting output voltage. In this article, I will introduce the missing link between these two technologies—a level-shifting circuit that combines them. Applications requiring negative output voltage include: testing and measurement, aerospace and defense, automotive, and medical. A common method to create … Read more

Some battery-powered products, if not designed properly, may exhibit a phenomenon where the battery fails to charge after being over-discharged. The reason is generally that these products lack a dynamic power path management feature in their charging design. When the battery is depleted and charging begins, the product typically activates certain functions to display charging … Read more
