When you first start learning about microcontrollers, you might feel excited when you successfully light up an LED or a seven-segment display using your code. This is a good thing and serves as motivation to continue learning. However, when it comes to experiments related to data communication, you may find it difficult to make progress. … Read more
⚔️First, let’s see the effect (Serial Print) ⚔️Principle (from AI) ⚔️Hardware Preparation Connect the ESP32’s touch pin, preferably using wires to connect it to a piece of tin foil for easy finger contact. Identify the ESP32’s touch pin. Many IOs have touch functionality; the author uses IO4. ⚔️Driver Code Implementation Configure IO4 as input. ⚔️Driver … Read more
After years of low-power hardware design (the hardware and software design in the company are separate, and I have always worked on hardware, often facing the challenges of low-power production incidents), one common issue is that the IO configuration is not set correctly before the microcontroller enters sleep mode. The main problems with the product … Read more
STM32CubeIDE is an integrated development environment officially launched by ST, which integrates code writing, compilation, debugging, and downloading functions, and includes the graphical configuration tool STM32CubeMX. It supports the HAL library and provides a complete solution from hardware configuration to firmware development, making it especially suitable for beginners and rapid prototyping.The combination of Keil and … Read more
