小e 电子表

闲来无事，用小e做了个电子表，时间从网络自动获取，运行界面如下图所示：


源代码：

1. #include <ESP8266WiFi.h>
   
2. #include <time.h>
   
3. #include <Wire.h>
   
4. #include "SSD1306.h"
   
5. 
   
6. 
   
7. const char* ssid = "xxx"; //wifi name
   
8. const char* password = "xxxxx"; //wifi password
   
9. 
   
10. // Initialize the oled display for address 0x3c
    
11. //I2C-ADD=0X3C, sda-pin=2 and sdc-pin=14
    
12. SSD1306 oled(0x3c, 2, 14);
    
13. 
    
14. void setup()
    
15. {
    
16.         Serial.begin(115200);
    
17. 
    
18.         Serial.setDebugOutput(true);
    
19. 
    
20.         WiFi.mode(WIFI_STA);
    
21.         WiFi.begin(ssid, password);
    
22.         Serial.println("\nConnecting to WiFi");
    
23.         while (WiFi.status() != WL_CONNECTED)
    
24.         {
    
25.                 Serial.print(".");
    
26.                 delay(1000);
    
27.         }
    
28. 
    
29.         configTime(8 * 3600, 0, "pool.ntp.org", "time.nist.gov");
    
30.         Serial.println("\nWaiting for time");
    
31.         while (!time(nullptr))
    
32.         {
    
33.                 Serial.print(".");
    
34.                 delay(1000);
    
35.         }
    
36.         Serial.println("");
    
37. 
    
38.         oled.init();
    
39.         oled.flipScreenVertically();
    
40. }
    
41. 
    
42. void loop()
    
43. {
    
44.         time_t now = time(nullptr);
    
45.         String currenttiem = ctime(&now);
    
46.         Serial.println(currenttiem);
    
47.         String hms = currenttiem.substring(11, 19);
    
48.         String date = currenttiem.substring(0, 11)+currenttiem.substring(20);
    
49. 
    
50.         oled.setFont(ArialMT_Plain_16);
    
51.         oled.setTextAlignment(TEXT_ALIGN_LEFT);
    
52.         oled.drawString(0, 0, date);
    
53. 
    
54.         oled.setFont(ArialMT_Plain_24);
    
55.         oled.setTextAlignment(TEXT_ALIGN_LEFT);
    
56.         oled.drawString(0, 30, hms);
    
57. 
    
58.         oled.display();
    
59.         oled.clear();
    
60. 
    
61.         delay(1000);
    
62. }
