With the rapid advancement of technology, the once bulky and heavy oscilloscope can now easily fit in your pocket, revealing the mysteries of the electronic world anytime, anywhere. This is not only a symbol of technological innovation but also the ultimate interpretation of portability and practicality. Recently, I discovered a striking small oscilloscope project whose … Read more
In embedded development, an oscilloscope is an essential debugging tool that allows developers to visually observe the signal waveforms in circuits, helping them quickly locate issues. However, traditional oscilloscopes are expensive and bulky, making them unsuitable for portable development. The ESP32, as a powerful Wi-Fi microcontroller, has abundant GPIO resources and strong processing capability, making … Read more

Basic Requirements: Use the built-in ADC of the Arduino Uno to measure voltage input and output it to the serial port. Use the “Serial Plotter” on the PC side to view the corresponding waveform. Advanced Requirements (Software): Understand the basic functions and working principles of an oscilloscope. Use timer interrupts for sampling to ensure a … Read more
When the LCD screen displays abnormally, in the past, we would deduce the parameters through the phenomenon, which was time-consuming and labor-intensive. With the long-storage oscilloscope, debugging the LCD controller is no longer a headache… When the LCD screen displays abnormally, in the past, we would deduce the parameters through the phenomenon, which was … Read more
