개발 및 시험을 위한 필수 전자공학 실험 장비
How to Build a Practical Electronics R&D Lab on a Budget Developing an electronic product requires more than designing a circuit and writing firmware. Engineers must measure electrical signals, verify power supplies, debug communication interfaces, evaluate PCB performance, and test the product under different operating conditions. For individual engineers, independent developers, startups, and small engineering […]
MCU, PWM, SPI 및 UART 디버깅을 위한 최고의 오실로스코프
A Practical Guide for Embedded Systems Engineers When developing embedded systems, an oscilloscope is more than a tool for measuring voltage. It helps engineers identify startup failures, unstable reset signals, incorrect PWM timing, serial communication errors, and power-supply noise. For projects involving microcontrollers, LCD interfaces, PC communication, and high-speed control signals, choosing the right oscilloscope […]
전자 공학자에게 가장 적합한 오실로스코프: 개인용 vs. 전문 실험실 장비
Introduction An oscilloscope is one of the most important instruments for electronics engineers. It allows you to observe electrical signals over time and investigate problems that cannot be diagnosed easily with a digital multimeter alone. Whether you are a hobbyist building electronic circuits, an embedded engineer debugging a microcontroller, or a professional working in an […]
NXP MPC5748G를 이용한 다중 코어 임베디드 시스템 설계
Introduction Modern embedded systems often need to perform several tasks simultaneously. A controller may need to process input signals, update an LCD, communicate with a PC, and maintain reliable control timing. Running all these functions in a single software execution path can make firmware more difficult to organize and maintain. A multicore microcontroller provides an […]
CR2032 Battery Design: Battery Life, Voltage Stability, and Flash Programming Errors
A CR2032 coin-cell battery is widely used in compact and handheld electronic devices because of its small size, low cost, and relatively long operating life. However, designing a device around a CR2032 battery requires more than simply calculating how long the battery will last. Two important design considerations are: A device may continue to operate […]
