我试图对组件进行重新编程，但是从教程中编译代码时遇到了一些错误。
这是我尝试从顶部和底部温度传感器读取和打印值的代码。
#include "mbed.h"
#include "MAX14720.h"
#include "MAX30205.h"
//Define all I2C addresses
#define MAX30205_I2C_SLAVE_ADDR_TOP (0x92)
#define MAX30205_I2C_SLAVE_ADDR_BOTTOM (0x90)
#define I2C_ADDR_PMIC (0x54)
// I2C Masters
I2C i2c1(I2C1_SDA, I2C1_SCL); // used by MAX30205 (1), MAX30205 (2), BMP280
I2C i2c2(I2C2_SDA, I2C2_SCL); // used by MAX14720, MAX30101, LIS2DH
//Top Local Temperature Senso
MAX30205 MAX30205_top(&i2c1, MAX30205_I2C_SLAVE_ADDR_TOP);
//Bottom Local Temperature Sensor
MAX30205 MAX30205_bottom(&i2c1, MAX30205_I2C_SLAVE_ADDR_BOTTOM);
// PMIC
MAX14720 max14720(&i2c2,I2C_ADDR_PMIC);
DigitalOut led(LED1);
//Serial
Serial pc(USBTX, USBRX);
int main()
{
max14720.boostEn = MAX14720::BOOST_ENABLED;
max14720.init();
led = 0;
// Temperature Variables
uint16_t rawTemp_top, rawTemp_bottom;
float celsius_top, celsius_bottom;
// Endless loop
while(1) {
// Read temperature
MAX30205_top.readTemperature(&rawTemp_top);
MAX30205_bottom.readTemperature(&rawTemp_bottom);
// Convert to Celsius
celsius_top = MAX30205_top.toCelsius(rawTemp_top);
celsius_bottom = MAX30205_bottom.toCelsius(rawTemp_bottom);
// Print Celsius Values
pc.printf("Top Temperature: %.2f\370C\n\rBottom Temperature: %.2f\370C \n\n\r", celsius_top, celsius_bottom);
// Wait 1 second
wait(1);
}
}
这里有MAX30205的库（用于温度传感器）
MAX30205.h

这会将传感器值打印到终端上。
此示例还包括来自BMP280气压传感器的数据，但如果愿意，可以轻松删除。您还可以轻松添加其他MAXREFDES100传感器。
