PAGE 47无线投票器的设计摘要：本设计以直流电压源为核心，STC89C52RC增强型单片机为主控制器，单片机系统是无线投票器的核心。它通过软件的运行来控制整个系统的工作，从而完成设定的功能。通过三个数字键盘来进行投票，三个按键之中任意两个按下系统便认为投票通过，用24L01无线模块发射出去。在接收端，可由液晶屏LCD1602显示实际投票结果，当三个按键中任意两个按下时，系统在1602液晶上显示Pass，反之显示Down.实际测试结果表明，本系统实际应用于投票领域。关键词：无线；投票器；单片机；24L01；STC89C52RCThe design of wireless voting device Abstract: In this design, the DC voltage source as the core, STC89C52RC enhancedmicrocontroller-based controller, microcontroller system is the core of the wirelessvoting device. It through the operation of the software to control the instrument, thus completing the set function. Three numeric keypad to vote on any two of three keypress thinks that voted to launch out using 24L01 wireless module. Be LCDLCD1602 displays the actual voting results at the receiving end, when any two of thethree buttons is pressed, the system in the 1602s LCD display Pass, contrary ShowDown. Actual test results show that this system is actually used in the voting field.Keywords: Wireless; voting machine; microcontroller; 24L01; STC89C52RC 目 录TOC \o 1-3 \h \u HYPERLINK \l _Toc15602 1 引言 PAGEREF _Toc15602 1 HYPERLINK \l _Toc4336 2 设计要求及方案论证 PAGEREF _Toc4336 2 HYPERLINK \l _Toc30775 2.1 设计要求 PAGEREF _Toc30775 2 HYPERLINK \l _Toc13707 2.2 设计方案及论证 PAGEREF _Toc13707 2 HYPERLINK \l _Toc3397 2.2.1 控制模块方案及论证 PAGEREF _Toc3397 2 HYPERLINK \l _Toc23398 2.2.2 显示模块方案及论证 PAGEREF _Toc23398 2 HYPERLINK \l _Toc9163 3.系统的硬件电路设计 PAGEREF _Toc9163 4 HYPERLINK \l _Toc23087 3.1 主控制器模块的设计 PAGEREF _Toc23087 4 HYPERLINK \l _Toc20598 3.2 NRF24L01无线模块的设计 PAGEREF _Toc20598 5 HYPERLINK \l _Toc2233 3.3 按键控制模块的设计 PAGEREF _Toc2233 7 HYPERLINK \l _Toc6236 3.4 液晶显示模块的设计 PAGEREF _Toc6236 8 HYPERLINK \l _Toc25374 3.4.1 LCD1602主要管脚介绍 PAGEREF _Toc25374 8 HYPERLINK \l _Toc27909 3.4.2 LCD1602控制指令 PAGEREF _Toc27909 9 HYPERLINK \l _Toc19260 3.4.3 液晶显示程序设计 PAGEREF _Toc19260 10 HYPERLINK \l _Toc19843 3.4.4 读写控制时序如表6所示 PAGEREF _Toc19843 10 HYPERLINK \l _Toc32220 3.4.5 LCD1602的一般初始化过程 PAGEREF _To
