1、arduino代码如下：

可直接进行串口打印或者oled显示（spi）

#include <Wire.h>
#include <math.h>
#include <Adafruit_GFX.h>
#include <Adafruit_SSD1306.h>

#include <MsTimer2.h> 
#include "TSL2581.h"
//---------------------------TDS-----------------------------------
#include <OneWire.h>
#include <DallasTemperature.h>
//-----------------------------------------------------------------
#include <SoftwareSerial.h>      //开启软串口
 
 
SoftwareSerial mySerial(2 , 3); //第2= RX,第3= TX   //开启软串口
WaveShare_TSL2581 tsl = WaveShare_TSL2581();

#define SCREEN_WIDTH 128 // OLED display width, in pixels
#define SCREEN_HEIGHT 32 // OLED display height, in pixels

// Declaration for SSD1306 display connected using software SPI (default case):
#define OLED_MOSI   9
#define OLED_CLK   10
#define OLED_DC    11
#define OLED_CS    12
#define OLED_RESET 13
Adafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT,
  OLED_MOSI, OLED_CLK, OLED_DC, OLED_RESET, OLED_CS);

#define NUMFLAKES     10 // Number of snowflakes in the animation example

#define Blank_KEY      7
#define Dark_KEY_INT   1
#define LED_Control    8
