按键控制数码管和流水灯设计报告实验报告 摘要 单片机自世单年代以～以其高的性价比～以及方便小巧受到来极2070 人单大的重单和单注。本单单单用极芯片作单控制芯片～单单矩单单单单来msp430f249 数内单管单示的控制。通单单片机的部控制单单单硬件单路的单单从而单单单LED,4*4 矩单单单的单单单单。用单片机的口单接矩单单单～以单片机的并,口P34×4P3.0P3.3 作单单单入的列单～以单片机的,口作单单单单入的行单～然后用,P3.4P3.7P0.0 作单出单～通单上拉单阻在单示器上单示不同的字符“,。在硬件单路P0.70F” 的基单上加上单件程序的控制单单本单单。其工作单程单,先判是否有单按下来断～ 如果有单按下～单单单单单整程序～如果有单按下～单单单是一单按下～最没个哪个 后通单数号单管单示单按单所单单的序。LED 单片机、流水、单管、控制系单灯数单单字, SCM since the nineteen seventies, with its high price, and a convenient compact attention and great concern. Thisdesign uses msp430f249 chip as the control chip, to realize the control of the LED digital tube display matrix keyboard. Through the internal control single chip to realize the hardware design of the circuit, so as to realize the detection and recognition of 4*4 matrix keyboard. 4 * 4 matrix keyboard connected with the MCU P3 port, and the MCU P3.0 P3.3 port for a keyboard input, MCU P3.4P3.7 port as the lines of keyboard input, and then use theP0.0 P0.7 as the output line, by a pull-up resistor display different characters "0F on display". Control with software programs based on the hardware circuit to realize the design. The working process is: first to determine whether a key is pressed, if no key is pressed, it will continue to test the whole procedure, if a key is pressed, the SCM, water lights, digital tubes, control systemKeywords: 单单控制流水和单管单单单告灯数 目单 单单的目的一....................................................................2 二 任单描述及方案单单 ...................................................3 任单描述1. ....................................................................................3 方案单单2. .....................................................................................3 on?comprous?documents.on.?documenticatiehensihrvar?operve?ee)(tiy??a?atispeciof?he?mprove?qualtve?fitto?iiace,?and?n?anguage?strplin?the?ldeas?iace,?in?plntenteaderions?shihe?ip?understn?torie?ensure??imatanding?of?fstthe?documentthe?check,?lyl?er?ower?check,he??and?check?upper?adhere?format?befand?cy?to?tes,?and?contore?and?aftldocumentent,?polpr?s?ict?oceduraudiris,t,?storteff?aspects?of?ed?allint?checks,ng??pr?auditofi?documents,he?draftn?tStory?awarts?irengty.cteness,?qual?t?mastihenieffit?qualier?wo)?ng?document?documentstrors.he?(tmajor?orerr?tresponsible?fTo ...........................................................................3三硬件单单方案 单片机的功能单明1.
