[Tinyos-help] imu interfacing with imote2 via i2c bus

[Fatma Faruq]

the following code doesnot compile with following errors

  I2CSCL.setGAFRpin not connected
  I2CSCL.setGPDRbit not connected
  I2CSDA.setGAFRpin not connected
  I2CSDA.setGPDRbit not connected

We dont know how to resolve these errors
