Design of dynamic screen system based on MCU
The design uses AT89C51 series of high-speed microcontroller as the main control module, using a simple peripheral circuit to drive the 32 * 16 dot matrix LED display. It consists of microcontroller, gating circuit, row and column driver circuit, display circuit. The design uses parallel transmission and dynamic scanning technology. Using the principle of LED display, this article elaborates LED dynamic display, as well as hardware design, software design.
