標(biāo)題: 基于51單片機(jī)16X32LED點(diǎn)陣顯示屏程序設(shè)計(jì)+仿真
51單片機(jī)16X32LED點(diǎn)陣顯示屏由單片機(jī)最小系統(tǒng)、行驅(qū)動(dòng)電路74HC154、列驅(qū)運(yùn)電路74HC595組成，實(shí)現(xiàn)漢字、數(shù)字的顯示。電路簡(jiǎn)單。程序中以20個(gè)漢字作為顯示示例。資料含51單片機(jī)C語(yǔ)言源程序、PROTEUS7.8仿真源文件。附送取模軟件及取模說(shuō)明文檔，方便你自己更換顯示內(nèi)容。顯示移動(dòng)速度可在程序中進(jìn)行設(shè)置。
