So far, the project has integrated LVGL with STM32F407 and also supports touch screens using STM32F407 + SPI for resistive touch screens. Therefore, integrating the touch screen with LVGL is a natural progression. You can refer to the official documentation at https://docs.lvgl.io/master/details/main-modules/indev/overview.html#indev-creation. It is simpler to refer to an official example template, especially for touch … Read more
In this digital age, innovations in input devices are emerging continuously. Today, we present a creative project that combines the functionalities of a game controller with traditional input devices—a USB mouse and keyboard based on the ESP32-S2. With simple hardware configuration and Arduino programming, you can achieve: Shake the game controller to simulate mouse movement; … Read more
Learning about PLCs is not enough if you only understand the PLC itself. The PLC is the “brain,” while the peripheral devices are its “eyes, ears, hands, and feet.” A qualified automation engineer must be proficient in how these peripheral devices work in conjunction with the PLC. Below are the core peripheral devices that one … Read more
