求助，ds18b20和max30100不能同时运行的问题
只有把loop函数里红色那俩行注释掉，心率和血氧的值才有变化，否则一直是0，而两个模块单独运行则没有问题，求解答！#include <Wire.h>
#include "Wire.h"
#include "MAX30100_PulseOximeter.h"
//#include <Adafruit_MLX90614.h>
#include <Adafruit_GFX.h> //Include Adafruit GFX Library
#include <OneWire.h>
#include <DallasTemperature.h>
#include <Adafruit_SSD1306.h> //Include Adafruit OLED Library
#define PIN_BEEP 14
#define ONE_WIRE_BUS 4
#define REPORTING_PERIOD_MS 1000
#define SCREEN_WIDTH 128 // OLED display width, in pixels
#define SCREEN_HEIGHT 64 // OLED display height, in pixels
#define OLED_RESET 4 // Reset pin # (or -1 if sharing Arduino reset pin)
