linux - 对象 <#BeagleBone> 没有方法 'i2cConfig' 尝试使用 Beaglebone-IO 运行 MPU6050

Question

尝试将 MPU6050 连接到在 Beaglebone-IO 下运行 Debian、Node.js 和 Johnny-Five 的 Beaglebone Black。

使用 Johnny-Five 示例初始化 MPU6050:

var imu = new five.IMU({
  controller: "MPU6050"
});

每次发生错误时:

TypeError: Object #<BeagleBone> has no method 'i2cConfig'
at EventEmitter.Drivers.MPU6050.initialize.value (/root/node_modules/johnny-five/lib/imu.js:42:12)
at Object.Drivers.get (/root/node_modules/johnny-five/lib/imu.js:345:12)

at Board.emit (events.js:92:17)
at process._tickCallback (node.js:419:13)

我猜这与 i2c 配置有关，因为我无法使用 npm install i2c 安装 i2c，它总是输出:

make: *** [Release/obj.target/i2c/src/i2c.o] Error 1
make: Leaving directory `/root/node_modules/i2c/build'

看起来 Beaglebone-IO 尚未获得更新的 I2C 支持:https://github.com/julianduque/beaglebone-io/pull/16/files
