可以先按照gitbook的方法确认模块是否正常工作然后用如下代码测试

#include <MikuDuino.h>
#include <Wire.h>
void setup()
{
Wire.begin();
}
void loop()
{
Wire.requestFrom(72, 2);
while(Wire.available())
{
int part1 = Wire.read();
int part2 = Wire.read();
printf("result is : %.1f\r\n",part1+part2/256.0);
printf("-----------------\r\n");
}
delay(500);
}
运行效果如下图
