[讨论] 【评测】基于UNO开发板的DGUS串口屏使用与评测 |
大家好,我是萌萌哒的新人Bill。今天很高兴得为大家带来基于DFRobot的uno开发板的DUGS串口屏的评测。之前搜了一下,DFRobot貌似还没有关于触控屏方面的测试,这次的操作有点复杂,不过总体的难度其实不高,而且最后的效果还是不错的,大家有机会可以尝试一下。PS:如果这次大家觉得这篇评测前后的行文风格不一致,大家可以尽情去投诉Angelo,写惯了技术文档,要写一篇思路广、欢乐多的评测还真是难啊,大家多多包涵下。 废话不多说,先上一段完成后的效果视频吧。 这里我一共写了两个页面,第一个页面显示温度,第二页面显示湿度,可以点击通过右下角的小图标来相互切换。温度页面有个曲线显示的功能,能够不断刷新当前的温度;湿度页面有个类似仪表盘的百分比显示功能。理论上效果还能做的更酷炫点,不过楼主不仅眼残、而且手残,在做一下午的美工,画了无数弯弯的直线后终于放弃了。嗯。。。反正我们数据符合比例就行了。。。 简单的介绍完了后,我们该展示怎么搭建这个项目吧,首先你需要如下的部件和工具 然后连接图如下配置 然后因为DGUS屏默认的串口通讯方式为RS232,而Arduino的为TTL,所以你需要把下图中红色框中的引脚焊上才能正常通讯。 系统完成后的示意图如下(偷偷告诉大家一个小技巧,我搭建的时候连了BT/APC上的串口端口,这样TX、RX端还可以再连一个USB转串口来监听双方的通讯,来进行debug) 系统搭建完成后,我们首先配置DGUS上的程序。下面的网盘里有DGUS基本操作和软件,其中的DGUS配置软件视频教程大家可以重点看下1_新建工程及打开工程.wmv,2_图标库生成.wmv,3_基本触控.wmv,4_数据显示及录入修改.wmv,9_曲线显示.wmv,12_仪表盘.wmv,17_串口通信.wmv 1.DGUS开发资料: 云盘链接: http://pan.baidu.com/s/1dD1mMel 2.DGUS开发配套软件: 云盘链接 http://pan.baidu.com/s/1dD5pNLf 3.视频教程: 云盘链接 http://pan.baidu.com/s/1kTwWhnh 这里我只是介绍下,如果配置我们这工程。首先你需要做好页面,这次做的比较简单的。我是网上随便搜点图图标,然后用windows自带的画图工具随便摆下大致就好了。然后第一张图的坐标和第二张的刻度表之所以看起来比较挫,是因为网上没有找到合适的。。。 画好图后,我们打开。选择共管理中的新建工程 屏幕属性设置 根据型号来定,这里的尺寸是480X272。然后我们点击欢迎使用回到初始界面,点击DGUS配置工具中的图片转换,选择Add来添加之前做好的页面图片,Images Conversion来转换图片,注意左上的Size内的分辨率应为480x272。然后把生成的图片文件重命名,第一页为0.bmp,第二页为1.bmp以此类推。图片转换完毕后点击加入图片。点击上方按钮设置好。如果采用不同波特率或者串口帧R3或者RA,代码的相对应部分也要进行修改 根据DWIN的教学视频配置好6个控件。其中有难点的1、2、3、4号控件的配置图如下 最后,大家喜闻乐见的配置好的DGUS文件test.rar 把test文件夹下内容复制到一张空microsd卡,然后插到DGUS屏上的sd卡槽上即可。 接下来arduino上的代码。t-sensor.rar [mw_shl_code=applescript,true]#include <DFRobotDGUSLcd.h> #include <SHT1x.h> // Specify data and clock connections and instantiate SHT1x object #define dataPin 10 #define clockPin 11 SHT1x sht1x(dataPin, clockPin); DFRobotDGUSLcd cmdTemperature(WriteVal,0x0000); //the address of the variable that shows temperature in the LCD is 0x0000 DFRobotDGUSLcd cmdTemperatureFlow(WriteChannel,0x01); //use channel 0 to show the curve DFRobotDGUSLcd cmdHumidity(WriteVal,0x0020); //the address of the variable that shows humidity in the LCD is 0x0020 DFRobotDGUSLcd cmdHumidityPanel(WriteVal,0x0010); //the address of the variable that shows humidity panel in the LCD is 0x0010 void setup() { pinMode(13, OUTPUT); Serial.begin(115200); cmdTemperature.begin(Serial); } void loop() { float temp_c; float temp_f; float humidity; // Read values from the sensor temp_c = sht1x.readTemperatureC(); temp_f = sht1x.readTemperatureF(); humidity = sht1x.readHumidity(); //write the serial stream cmdTemperature.write(sht1x.readTemperatureC() *100); cmdTemperatureFlow.write(0,temp_c *100); cmdHumidity.write(humidity*100); cmdHumidityPanel.write(humidity); delay(500); // Print the values to the serial port Serial.print("Temperature: "); Serial.print(temp_c, DEC); Serial.print("C / "); Serial.print(temp_f, DEC); Serial.print("F. Humidity: "); Serial.print(humidity); Serial.println("%"); }[/mw_shl_code] 以及我写的库文件DFRobotDGUSLcd.h和DFRobotDGUSLcd.cpp的代码,基本DGUS的串口5条指令都基本实现了,但更复杂的则有待于完善 DFRobotDGUSLcd.h [mw_shl_code=applescript,true]#ifndef _SERIAL_LCD__ #define _SERIAL_LCD__ #if ARDUINO >= 100 #include "Arduino.h" #else #include "WProgram.h" #endif #define WriteReg 0x80 #define ReadReg 0x81 #define WriteVal 0x82 #define ReadVal 0x83 #define WriteChannel 0x84 class DFRobotDGUSLcd { private: uint8_t R3;
