Best Oscilloscopes for MCU, PWM, SPI, and UART Debugging

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 […]

Multicore Embedded System Design Using NXP MPC5748G

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 […]

High-Speed LED Strobe Controller Version-Up: MPC5744P-> MPC5748G, Lattice CPLD, SIO, and Extended Duty/Clock Range

Introduction High-speed LED strobe controllers are widely used in machine vision, industrial inspection, optical measurement, and automated manufacturing systems. In the original design, I developed a high-speed LED strobe controller using an NXP MPC5744P microcontroller, Lattice CPLD, TFT display, and high-speed line-driver switching device. As system requirements increased, the controller was upgraded from the MPC5744P to […]

High-Speed LED Strobe Controller Design: NXP MPC5744P, Lattice CPLD, and Line Driver Switching

Designing a high-speed LED strobe controller requires more than simply turning an LED on and off. When an LED must be switched at high speed and synchronized with an external system, the controller needs accurate timing, fast digital logic, stable power, appropriate switching devices, and careful signal-integrity design. In one of my real-world engineering projects, […]
