Better Angles. Better Flow. Better PCBs. Figure 1: Visual comparison of 90°, 45°, and Arc/Fillet trace routing on a PCB Introduction PCB trace routing is far more than connecting dots on a board. Every bend, corner, and curve in a copper trace directly affects signal integrity, manufacturing yield, and long-term reliability. Among the most misunderstood aspects of PCB layout is the treatment of trace angles — specifically, why the industry standard strongly discourages routing at 90-degree...

STM32CubeIDE is a powerful Eclipse-based development environment used for building and debugging applications on STM32 ARM microcontrollers. It provides integrated tools for code generation, compilation, and debugging. For advanced debugging scenarios, external debug probes such as PEMicro Cyclone and PEMicro Multilink can be used. These devices extend debugging capabilities through a dedicated Eclipse GDB plugin, enabling seamless integration with STM32CubeIDE. This article explains how to...

In this article, I will show how I analyse I2C communication using a Saleae logic analyzer. This tutorial explains the basic setup, how to capture signals, how to enable the I2C protocol analyzer, and how to understand the decoded data. The same method can be used when debugging communication between a microcontroller and peripheral devices such as sensors, EEPROM, or display controllers. I2C is one of the most used serial communication protocols in embedded systems. It uses two signals,...
