Design of Color Screen Clock Control System Based on STM32

摘要

For the lack of humanization of alarm clock design in the market, that is, LED display and monotonous electronic sound are widely used, a color screen alarm clock control system is proposed in this paper, which is controlled by STM32. FATFS is transplanted to improve the capacity of memory and carry out diversified data processing; the bitmaps in the SD card are read and analyzed, and then displayed on the TFT LCD screen; different music and pictures are stored in SD card to give different ringtones and change different themes to ease people’s mood. On APP, the clock is adjusted via WIFI to avoid cumbersome operation caused by the use of physical keys. The alarm can be turned off by non-contact induction of infrared sensor. Finally a diversified and humanized color screen alarm clock control system is realized.
