这是英特尔运行加速度计(Grove数字)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.getRawValues(); // Read raw sensor data
var force = adxl.getAcceleration(); // Read acceleration force (g)
var rawvalues = raw.getitem(0) + " " + raw.getitem(1) + " " + raw.getitem(2);
console.log("Raw Values: " + rawvalues);
console.log("ForceX: " + force.getitem(0).toFixed(2) + " g");
console.log("ForceY: " + force.getitem(1).toFixed(2) + " g");
console.log("ForceZ: " + force.getitem(2).toFixed(2) + " g");
}, 1000);
它构建并上传到Edison Arduino板,但在运行时抛出此错误:
ERROR: /home/root/.node_app_slot/main.js:10
ERROR: var adxl = new adxl345.Adxl345(0);
ERROR: ^

有什么想法吗?加速度计连接到I2C端口。另一个传感器(温度)工作正常。
答案 0 :(得分:0)
grove acceleremoter不是ADXL345,而是MMA7660,如here所述。
以下是MMA7660的upm代码
SELECT roles.id, permissions.id FROM roles INNER JOIN permissions;
