前言
作了个b站的粉丝显示器，挺好好玩的，记录一下踩过的坑
使用u8g2库
具体可以参考菜鸟哥的教程,说些容易出错的地方
1.如果单片机是esp8266，0.96寸的应该在有如下东西
#define SDA 4
#define SCL 5
U8G2_SSD1306_128X64_NONAME_F_SW_I2C u8g2(U8G2_R0, /* clock=*/ SCL, /* data=*/ SDA, /* reset=*/ U8X8_PIN_NONE);
// All Boards without Reset of the Display
2.如果要用u8g2.print,记得在初始化的时候加上
u8g2.enableUTF8Print();
3.关于string转const *char
可以参考这篇博客
，我是这样用的。
String str= timeClient.getFormattedTime();
const char* p=str.c_str();
u8g2.drawStr(15,30,p);
实时显示时间
有些up主，用时间戳显示时期/星期/时间，挺麻烦的，主要是我time库总是包错，应该是，，类型不对。也一直没有解决，就偷了个懒，只显示时间了啦!
附上测试时候的小代码
#include
// change next line to use with another board/shield
#include
//#include // for WiFi shield
//#include // for WiFi 101 shield or MKR1000
#include
const char *ssid = "@xxxxx";
const char *password = "xxxxxx";
WiFiUDP ntpUDP;
NTPClient timeClient(ntpUDP, "ntp1.aliyun.com",60*60*8, 30*60*1000);
void setup(){
Serial.begin(115200);
WiFi.begin(ssid, password);
/* 最好注释调这里，要不然后面会出错
while ( WiFi.status() != WL_CONNECTED ) {
delay ( 500 );
Serial.print ( "." );
}*/
timeClient.begin();
}
void loop() {
timeClient.update();
String a ;
a=timeClient.getFormattedTime();
Serial.println(timeClient.getFormattedTime());
Serial.println(a);
delay(1000);
}
至于日期就自己画上区了啦
爬去b站的数据
可以用以下代码爬取b站的很多资料啦，具体可以在串口监视器里面看到，然后就是对这里的数据进行json解析，拿去出我们想要的信息啦
bool getJson()
{
bool r = false;
http.setTimeout(HTTP_TIMEOUT);
//followe
http.begin("http://api.bilibili.com/x/relation/stat?vmid=" + biliuid);
int httpCode = http.GET();
if (httpCode > 0){
if (httpCode == HTTP_CODE_OK){
response = http.getString();
//Serial.println(response);
r = true;
}
}else{
Serial.printf("[HTTP] GET JSON failed, error: %s\n", http.errorToString(httpCode).c_str());
r = false;
}
http.end();
//return r;
//view
http.begin("http://api.bilibili.com/x/space/upstat?mid=" + biliuid);
int httpCodeview = http.GET();
if (httpCodeview > 0){
if (httpCodeview == HTTP_CODE_OK){
responseview = http.getString();
Serial.println(responseview);
r = true;
}
}else{
Serial.printf("[HTTP] GET JSON failed, error: %s\n", http.errorToString(httpCode).c_str());
r = false;
}
http.end();
return r;
}

参考了很多的资料啦，总的效果图就有时间在放出来啦
