英特尔爱迪生node.js示例代码不适用于grove 3轴数字I2C加速计
这是Intel运行Grove digital加速度计的示例代码：英特尔爱迪生node.js示例代码不适用于grove 3轴数字I2C加速计,node.js,accelerometer,intel-edison,Node.js,Accelerometer,Intel Edison,这是Intel运行Grove digital加速度计的示例代码： // Load accelerometer var adxl345 = require('jsupm_adxl345'); // Instantiate on I2C bus var adxl = new adxl345.Adxl345(0); setInterval(function() { adxl.update(); // Update the data var raw = adxl.getRawValu
// Load accelerometer

// Instantiate on I2C bus
var adxl = new adxl345.Adxl345(0);
setInterval(function()
{
adxl.update(); // Update the data
var raw = adxl.getRawValues(); // Read raw sensor data

你有什么想法吗？加速计连接到I2C端口。另一个传感器温度正常。grove acceleremoter不是ADXL345，而是MMA7660，如前所述

您确定这是您的传感器类型吗？我相信正常的grove发送的是mma7660部分：我没有看到你的错误，但是当我运行adxl345代码时，我得到了虚假的值。另外，当你在串行连接中键入“configure_edison-version”时，你得到了什么？我现在在159号。
