摘要:本次設(shè)計(jì)是以STC12C5A60S2單片機(jī)為控制核心，控制2個(gè)16*16LED點(diǎn)陣顯示屏。本文主要介紹了STC12C5A60S2通過74HC164控制點(diǎn)陣顯示屏的行信號，以及通過74HC595控制點(diǎn)陣顯示屏的列信號來使得LED點(diǎn)陣顯示屏可以顯示各種文字、圖像等。文中詳細(xì)介紹了LED點(diǎn)陣和STC12C5A60S2單片機(jī)外圍硬件電路設(shè)計(jì)以及相應(yīng)各個(gè)模塊的功能、軟件設(shè)計(jì)等。本系統(tǒng)具有結(jié)構(gòu)簡單、環(huán)境適應(yīng)性好、可級聯(lián)等特點(diǎn)。 關(guān)鍵詞：STC12C5A60S2單片機(jī)； LED點(diǎn)陣顯示屏； 74HC164； 74HC595； 級聯(lián)
Abstract:This design is with the STC12C5A60S2 MCU (Micro programmed Controller Unit) at the core, by which the 2 16*16 lattice LED could be working. The paper mainly introduce how LED dot matrix display screen could show a piece of words or images and so on controlled row to row by 74HC164 and controlled column to column by 74HC595, and them controlled by STC12C5A60S2 MCU. This paper describes the hardware design of STC12C5A60S2 MCU peripheral circuits and LED dot matrix and the functions of all kinds of the circuit, the software design and so on. The system has the characteristics of structure simple, environment adaptive flexibly and cascaded. Key words: STC12C5A60S2 MCU; LED dot matrix display screen; cascaded; 74HC164; 74HC595 |
