九月一到，就有了秋意，秋意在一个多雾的黎明溜来，到了炎热的下午便不见踪影。它踮起脚尖掠过树顶，染红几片叶子，然后乘着一簇飞掠过山谷离开。秋天已悄悄到来，背上你的行囊，叫上你的小伙伴一起去外面看看缤纷的世界。这不我养的小青蛙已经出去旅行了，它总是会给我发一些它在旅游时候的照片，不过最近在外好像有了艳遇。给大家看看它寄回来的照片。<a

我每当我看到我这里天气的变好或变差的时候，我都会去看看我的蛙儿子在哪里旅行。

功能：
1.接受当地时间及当地天气，显示在屏幕上
2.使用ESP32-E的电容触摸引脚，切换屏幕显示内容，显示青蛙旅行图片

一、准备材料

1.硬件材料：

[*]ESP32-E主板
[*]3.7V电池
[*]3.7V电池充电器
[*]TFT屏幕
https://www.hualigs.cn/image/6168e394dc879.jpg

2.外壳打印：点击链接获取图纸

https://i.loli.net/2021/10/08/Q9ozn4wyaHBkMSX.jpg

二、制作过程

2.1 将各个模块按下图进行连接
https://www.hualigs.cn/image/6168e3b8ceb86.jpg

2.2 安装开发板和库文件
[*]关于如何下载本次使用的库文件，DFRobot_GDL库文件.
[*]关于如何使用Firebeetle Board-ESP32-E，点击链接。
[*]关于如何下载库文件，点击链接。

三、使用esp32获取网络天气及时间ESP32同时支持STA以及AP模式的WiFi连接。
[*]STA 模式：ESP32模块通过路由器连接互联网，手机或电脑通过互联网实现对设备的远程控制。
[*]AP 模式：ESP32模块作为热点，实现手机或电脑直接与模块通信，实现局域网无线控制。
[*]STA+AP 模式：两种模式的共存模式，即可以通过互联网控制可实现无缝切换，方便操作。

// printLocalWeather();
}

void loop() {

}
}

说明：本Demo实现了通过WiFi功能获取网络时间以及通过访问国家气象局提供的http://www.weather.com.cn/datalcityinfo/101010100.html来获取天气情况，本接口中“101010100"为城市代码。
注意：该例程需要下载ArduinoJson库，下载方式如下图

四、添加旋转太空人图片

4.1 旋转太空人的动态图，其实是从动态图里面截取下来的4张图片通过每100毫秒切换一张图片，达到旋转太空人的形态。
https://i.loli.net/2021/09/28/taSeBc5qIxT4mAj.jpg

4.2 把图片转换成数组
https://i.loli.net/2021/09/28/paJs1wi64lM7eUO.jpg

4.3 把图片的数组存放到.h文件下
https://www.hualigs.cn/image/6153c4b1bf980.jpg

4.4 图片的使用代码如下
#include <DFRobot_GDL.h>
#include "BMP.h"

#define TFT_DCD2
#define TFT_CSD6
#define TFT_RST D3
#define PICNUMBER 6

DFRobot_ST7789_240x240_HW_SPI screen(/*dc=*/TFT_DC,/*cs=*/TFT_CS,/*rst=*/TFT_RST);

void setup() {
screen.begin();

}

void loop() {
screen.drawPIC(/*x=*/0,/*y=*/124,/*w=*/124,/*h=*/124,/*bitmap gImage_Bitmap=*/( uint8_t*)gImage_black1);
delay(100);
screen.drawPIC(/*x=*/0,/*y=*/124,/*w=*/124,/*h=*/124,/*bitmap gImage_Bitmap=*/( uint8_t*)gImage_black2);
delay(100);
screen.drawPIC(/*x=*/0,/*y=*/124,/*w=*/124,/*h=*/124,/*bitmap gImage_Bitmap=*/( uint8_t*)gImage_black3);
delay(100);
screen.drawPIC(/*x=*/0,/*y=*/124,/*w=*/124,/*h=*/124,/*bitmap gImage_Bitmap=*/( uint8_t*)gImage_black4);
delay(100);
screen.drawPIC(/*x=*/0,/*y=*/124,/*w=*/124,/*h=*/124,/*bitmap gImage_Bitmap=*/( uint8_t*)gImage_black5);

}

4.5 图片动态展示
https://www.hualigs.cn/image/6153cae75e754.jpg

五、把从网络上获取到的天气和时间信息显示在TFT屏幕

5.1 python环境搭建       在使用setup.py脚本生成自定义字体之前，需要做如下准备:
[*]登录网址https://www.python.org/downloads/，下载python3.6及以上版本；

[*]安装完毕后，需要用下列命令安装python第三方依赖包:
[*]pip3 install numpy
[*]pip install freetype-py
[*]pip install chardet

5.2 生成自定义字体
      把ttf文件放在库文件的对应ttf文件夹下，这里我提供了一个ttf文件，供大家使用。点击链接获取

[*]将TTF字体文件存放在ttf文件夹里，例如：SIMKAI.TTF（简体字楷体）
[*]在text.txt文件中输入你想生成的字符，例如：你好，世界！
[*]打开config.txt文件，配置生成字体文件的名字前缀和字体大小
https://www.hualigs.cn/image/6153dc70518f5.jpg

5.3 在屏幕上显示

[*]运行setup.py脚本，会在font文件夹生成一系列后缀名为.h的字体文件，并弹出一个font.txt的文本，再进行以下步骤，即可在屏上显示：你好，世界！
[*]将font文件夹里的文件复制到DFRobot_GDL\src\Fonts\Fonts目录下;
[*]将弹出的font.txt的内容粘贴到DFRobot_GDL\src\Fonts\DFRobot_Font.h文件中;
[*]打开Arduino IDE，构造屏对象，如tft，调用tft.setFont(&SIMKAIFont48pt);
[*]调用tft.println("你好，世界！"),此时即可在屏上显示"你好，世界！"
https://www.hualigs.cn/image/6153fb3ad1714.jpg

5.4 显示天气和时间的代码如下#include <DFRobot_GDL.h>
#include <WiFi.h>

}

void printLocalWeather(){
http.begin("http://www.weather.com.cn/data/cityinfo/101270101.html");
int httpCode = http.GET();
if(httpCode == HTTP_CODE_OK){
   String pageData = http .getString();

   String cityWeatherinfo =weather;
   Serial.println("获得天气情况如下：");
   Serial.print(cityInfo);

   return ;
   }
   Serial.println(&timeinfo, "%F %R %u"); // 格式化输出

   //显示天气及时间信息
   screen.setFont(&simkaiFont72pt );//Set the font to FreeMono12pt7b

   screen.setCursor(/*x=*/124,/*y=*/0);
   screen.println(weekDays);
   screen.setFont(&simkaiFont24pt );//设置字体大小为24像素点大小
   screen.setCursor(/*x=*/130,/*y=*/70); //设置显示光标
   screen.println(cityWeatherinfo);//屏幕显示天气状况，如多云转晴类字样
   screen.drawPIC(/*x=*/125,/*y=*/200,/*w=*/24,/*h=*/24,/*bitmap gImage_Bitmap=*/( uint8_t*)gImage_black6);//屏幕显示位置图标
   screen.setFont(&simkaiFont36pt );//设置字体大小为36像素点大小
   screen.setCursor(/*x=*/120,/*y=*/135);//设置显示光标
   screen.println(tempInfo);//屏幕显示温度信息
   screen.setCursor(/*x=*/204,/*y=*/135);
   screen.println("°");//显示温度的符号
   screen.setCursor(/*x=*/150,/*y=*/190);
   screen.println(cityInfo);//屏幕显示你所在城市的位置信息

}else{
   Serial.println("GET ERR");
}
http.end();
}

void loop() {
if(WiFi.status() == WL_CONNECTED){
printLocalWeather();
}else{
Serial.println("WiFiDisconnect");
}

}

六、使用电容触摸显示青蛙儿子旅行照片

6.1 电容按键

ESP32提供了电容触摸传感器的功能, 共有T0,T2~T9 共 9个touch传感器可用.分别对应引脚4、2、15、13、12、14、27、33、32. 无需设置PinMode，touchRead()返回值为0~255. 触摸强度越大，返回值越小。烧录此例程，将使用4/D12引脚作为触摸按键，并通过串口监视器返回触摸值
void setup()
{
Serial.begin(9600);
}

void loop()
{
Serial.printf("touch:%d\n",touchRead(4));
}结果

}

void loop() {

if(WiFi.status() == WL_CONNECTED){

}else{

}
从这次的小应用中我学会了很多东西，比如在tft屏幕上显示图片、动态图、中文。如何抓取天气信息，如何把抓取到的信息显示到tft屏幕上。

所以去旅行吧，不理会繁杂的琐事，自由自在地，去体验一个城市，一段故事，留下一片欢笑。

屏幕使用的GDI接口，即插即用。天线就是用一根公公头导线插的16/D11号引脚。
