请教一下MPU6050的使用问题，谢谢
本帖最后由 shuaigou 于 2014-1-14 19:50 编辑Arduino Uno + MPU6050三轴,Arduino测试时全部是0,波特率38400 COM3我的是3,出来都是0刷新挺快的,是不是6050坏了?谢谢! 我用的是Arduino1.01 这个代码!

uno 要接中断，好像是int对应d2 wunanyx 发表于 2014-1-14 20:08 static/image/common/back.gif

谢谢老师回复!!d2你指的是?
不行啊!
:L 好啦！
把排针焊好，又仔细看了一下6050，突然发现A4\A5接反了:L，这个折腾啊！ 初学的菜鸟们看了引以为戒哦！！！:lol:lol:lol shuaigou 发表于 2014-1-15 10:03 static/image/common/back.gif
