E-albums

Overview

This article designs a multi-functional electronic photo album based on STM32F429 microcontroller. The system hardware consists of main control module, SD card module, LCD module, and USB communication module. The UI interface of this design uses the LVGL graphical interface library, uses DMA technology to increase the graphics refresh speed, and allows users to choose to display or switch pictures, use calculators or drawing functions through touch operations; this design integrates the system hardware into a circuit board, and designed a 3D printed shell for it, which has strong anti-interference ability and is easy to carry. The test results show that the partial refresh of the LCD screen of this product can reach up to 50 frames. It has the advantages of small size, low power consumption, high frame rate, and portability.
Hang it first and replenish it when you have time.
