軟件部分的編程采用C語言，一方面主要完成STM32F103對(duì)I/O 管腳的配置，用來實(shí)現(xiàn)對(duì)四線電阻觸摸屏端子狀態(tài)的控制，通過中斷方式檢測(cè)是否有觸摸信息，配置A/D轉(zhuǎn)換通道，讀入電壓根據(jù)公式計(jì)算出觸點(diǎn)坐標(biāo)。另一方面主要完成通過與TFT液晶模塊的通信控制，實(shí)現(xiàn)觸摸點(diǎn)坐標(biāo)與液晶屏坐標(biāo)的對(duì)應(yīng)并有效完成顯示任務(wù)。軟件的開發(fā)環(huán)境是MDK，MDK 將ARM 開發(fā)工具RealView DevelopmentSuite（簡(jiǎn)稱為RVDS）的編譯器RVCT與Keil的工程管理、調(diào)試仿真工具集成在一起，支持ARM7、ARM9和最新的 Cortex-M3核處理器，自動(dòng)配置啟動(dòng)代碼，集成Flash燒寫模塊，強(qiáng)大的Simulation設(shè)備模擬，性能分析等功能，與ARM 之前的工具包ADS等相比，RealView編譯器的最新版本可將性能改善超過20%.具體流程如圖6所示。
