專案總覽
先上圖，看效果！
該專案主要是通過esp8266-12e連接wifi獲取心知天氣資料和蘇寧時間api，通過決議json代碼得到資料，然后通過e-paper墨水屏顯示出來，本專案基于墨水屏例程，添加了部分中文字體以及天氣圖示，通過文字取模軟體對圖示和文字進行了編碼與取模，

- 蘇寧時間api：http://quan.suning.com/getSysTime.do
- 獲取到的代碼塊示例
{
"sysTime2": "2021-08-15 11:34:54",
"sysTime1": "20210815113454"
}
- arduinojson：https://arduinojson.org/assistant/
- 主要是用來esp8266決議獲取到的網頁資料
- 注意選擇v5版本
- 示例：需要決議的資料
{
"sysTime2": "2021-08-15 11:34:54",
"sysTime1": "20210815113454"
}
- 決議后的代碼
const size_t capacity = JSON_OBJECT_SIZE(2) + 60;
DynamicJsonBuffer jsonBuffer(capacity);
const char* json = "{\"sysTime2\":\"2021-08-15 11:34:54\",\"sysTime1\":\"20210815113454\"}";
JsonObject& root = jsonBuffer.parseObject(json);
const char* sysTime2 = root["sysTime2"]; // "2021-08-15 11:34:54"
const char* sysTime1 = root["sysTime1"]; // "20210815113454"
只需要將const char* json = 注釋掉，然后將json改為通過http獲取到的字串就可以了，
顯示屏部分
螢屏檔案介紹
https://heltec.org/project/154-e-ink/
通信協議：
- 三線spi：CLK+SDI+CS
- DC引腳+BUSY引腳
供電電壓：
- 3.3v （高電壓或低電壓都會造成亂碼顯示）
螢屏解析度（1.54英寸黑白墨水屏）：
- 200像素*200像素
螢屏文字影像取模
取模軟體：PCtoLCD2002完美版
取模方式
- 取模選項
- 取模示例：
如何理解：
每一行代表了像素點的位置，14號字體，寬度14像素，高度14像素，一共14行，每一行是兩個8為16進制數，最大可以表示16號字，
若需要表示更大的字，值需要在每一行加一個16進制數即可，依然是每一行表示對應的像素點位置，
{
0x02,0x00,
0x02,0x00,
0x05,0x00,
0x08,0x80,
0x14,0x40,
0x22,0x20,
0xC2,0x18,
0x00,0x00,
0x3F,0xC0,
0x00,0x40,
0x00,0x80,
0x00,0x80,
0x01,0x00,
0x02,0x00},/*"今",0*/
- 對應程式中的函式：
paint.DrawCharAt(120, 0, ’ '+9, &Fontzh14, COLORED);//今
第一、二個引數是列印位置x，y
第三個引數代表‘ ’字符加上第幾個元素，因為函式是從‘ ’開始檢索的
第四個引數用來選擇字號，需要用對應的font.c檔案，還需要再font.h檔案中進行結構體宣告
第五個引數用來選擇列印顏色，colored即為前景色，黑色
此函式與列印ascii碼的函式通用，需要顯示中文只需要改動對應字庫即可
添加字庫方法（中文英文通用）
-
首線復制一份font.c檔案并重新命名
-
然后在檔案中修改對應變數名，根據字號修改字符寬度和高度
-
在font.h檔案重新宣告變數
