大彩串口屏快速入门手册 V3.0 第1章安装 VisualTFT 软件所有串口屏的界面开发都是基于 VisualTFT 软件平台来操作 1.1 安装的环境需求该软件适合 XP/WIN7 32 位系统，磁盘空间需求 100M 左右，内存 128M 以上。WIN8 和 64 位操作系统暂不支持 USB 下载。最新支持驱动可以在官网进行查询。 1.2 软件安装 1. 开始安装。打开 VisualTFT 软件安装包，点击下一步，如图 1.1 所示。图 1.1 打开安装程序 2. 选择默认安装路径，直至安装完成。若安装过程中提示是否需要安装 USB 驱动，选择“始终进行安装”。 3. 安装完成后，桌面出现快捷图标。点击软件，显示界面如图 1.2 所示。图 1.2 VisualTFT 显示界面 4. 若界面工具栏或窗口被移动或隐藏，可以点击如所图 1.3 示的菜单“视图”，选择“恢复默认视图布局”。图 1.3 恢复默认视图布局 1 /37

大彩串口屏快速入门手册 V3.0 第2章串口屏与 PC 联机通信对于初次使用大彩串口屏的用户，建议首先进行屏幕与上位机 VisualTFT 联机通讯。上位机软件内置的 1 个指令调试助手，可以模拟用户单片机串口给屏幕发送指令，以便加快用户对产品使用的熟练度。 2.1 准备工具 1. 电源适配器 (建议 1A 以上，电压大小必须与手册或屏接口丝印标注的一致)； 2. 串口 232 电缆线（若电脑没有串口接口，建议用户在我司购买 USB 转串口电缆线）； 3. 串口调试板（购屏时配送，仅调试使用，批量无需用到）； 4. 8/10P 通信电缆线 (购屏时配送，用户连接调试板和屏)； 2.2 连接设备 1. 经济型、基本型和小尺寸 nano 系列联机连接图分别如图 2.1、图 2.2 和图 2.3 所示。提示：若用户使用的是 USB 转 TTL 串口调试板来联机，则需要将屏幕设置为 TTL 电平。我司所有屏幕出厂前均为 RS232 电平。 8P 电缆线和串口调试板图 2.1 基本型系列与 PC 软件联机示意图图 2.2 经济型系列与 PC 软件联机示意图 . 2 /37

RS485 和 86 系列联机。由于 485 无法与电脑 232 接口通讯，所以若用户需要屏与电脑联机，必须购买 RS485 转 232 模块，如图 2.4 所示。 485 转 232 串口图 2.4 RS485 转 232 模块 2.3 设备上电和开始联机 1. 设备上电。按照手册规定或接口丝印标识处的电压供电，上电后屏幕会显示出厂时烧录的图片。若产品支持触摸，点击按钮画面会进行跳转和蜂鸣器鸣叫。提示：若上电出现黑屏、闪动、点击触摸后黑屏、系统不断复位和电感发出声响等现象，大部分是由于电压功率不够引起。建议用户使用万用表测试屏接口 VCC 和 GND 的电压，看是否电压被拉低，譬如供电线太长、电脑 USB 供电均可能导致功率不够或电压拉低。 2. 联机设备。打开 VisualTFT 软件，点击图 2.5 所示工具栏的“联机设备”，系统会自动轮询匹配波特率，联机成功后，软件最右下角会显示“已连接设备”和版本号，如图 2.6 所示。若多次依然无法连接成功，请按照软件指令窗口的提示进行故障排除。注意：联机过程中，有任何问题，建议阅读《串口屏常见问题解答》，以便第一时间得到解决。 3 /37
