We encourage clear philosophical thinking in programming rather than rigid rules. I do not expect you to agree with everything, as they are merely opinions that change over time. However, if I had not written them down until now, these opinions, based on much experience, have long accumulated in my mind. Therefore, I hope these … Read more

Some may have noticed that the voltage standards for microcontrollers vary; some operate at 3.3V while others use 5V. Why isn’t there a unified standard? Is this a historical legacy issue or an inevitable result of technological evolution? Today, we will explore this question. 1. The Aftermath of the TTL and CMOS ‘Cold War’ The … Read more
In embedded system design, we often need to use the General Purpose Input/Output (GPIO) pins of microcontrollers (MCUs) to drive peripheral devices such as LEDs and relays. I still remember that my first code in college was to control the blinking of an LED using the 8051 microcontroller. I wonder if the current university courses … Read more
