2、心-專(zhuān)注-專(zhuān)業(yè)1. 題目基于ARM的嵌入式電子點(diǎn)菜系統(tǒng)2. 系統(tǒng)簡(jiǎn)介在基于ARM的嵌入式環(huán)境下，本電子點(diǎn)菜系統(tǒng)可實(shí)現(xiàn)的功能有：支持觸摸屏圖形選菜以及記錄菜單等功能。界面美觀，功能合理，基本達(dá)到了實(shí)驗(yàn)要求的內(nèi)容。3. 系統(tǒng)設(shè)計(jì)3.1設(shè)計(jì)背景隨著我國(guó)的餐飲企業(yè)的蓬勃發(fā)展，餐飲行業(yè)成為國(guó)內(nèi)最早的一個(gè)完 全市場(chǎng)化的行業(yè)，個(gè)體民營(yíng)占絕對(duì)優(yōu)勢(shì)和主導(dǎo)的行業(yè)，市場(chǎng)競(jìng)爭(zhēng)非常充分，在廣大的餐飲企業(yè)的經(jīng)營(yíng)者的不懈努力下，餐飲行業(yè)取得了非常突出的發(fā)展和進(jìn)步。3.2設(shè)計(jì)意義傳統(tǒng)的點(diǎn)菜方式由人工來(lái)傳遞菜單，不僅浪費(fèi)時(shí)間、效率低下；一旦生意火熱，單據(jù)多，信息量大時(shí)，分單、傳菜等環(huán)節(jié)很容易出現(xiàn)錯(cuò)誤，從而直接影響服務(wù)質(zhì)量。導(dǎo)致

3、企業(yè)造成不必要的損失。而本文介紹的電子點(diǎn)菜系統(tǒng)，大大降低人力資源成本，加快各環(huán)節(jié)之間的數(shù)據(jù)流通，對(duì)企業(yè)軟環(huán)境的檔次有較大提高。在以特色服務(wù)吸引客戶(hù)的同時(shí)，有效提高餐飲機(jī)構(gòu)的服務(wù)質(zhì)量和工作效率，為餐飲業(yè)創(chuàng)造更多利潤(rùn)。3.3總體設(shè)計(jì)圖1 實(shí)驗(yàn)程序流程圖3.4代碼編譯及注釋本實(shí)驗(yàn)要求實(shí)現(xiàn)部分：（1）、MainTask中按鍵消息獲取，處理（2）、按鍵處理函數(shù)OnKey()函數(shù)（3）、創(chuàng)建串口處理任務(wù)Serial_Receive_Task(void *Id)（4）、 實(shí)現(xiàn)串口消息換取，處理（在LCD或數(shù)碼管上顯示）函數(shù)OnReceive(char nRdata)初始化操作：void initOSGUI(
