Example
--Note: due to the use of sys.wait() all apis need to be used in the coroutine
-- Usage Examples
local adxl34x = require "adxl34x"
i2cid = 0
i2c_speed = i2c.FAST
sys.taskInit(function()
i2c.setup(i2cid,i2c_speed)
adxl34x.init(i2cid)--initialization, passing in i2c_id
while 1 do
local adxl34x_data = adxl34x.get_data()
log.info("adxl34x_data", "adxl34x_data.x"..(adxl34x_data.x),"adxl34x_data.y"..(adxl34x_data.y),"adxl34x_data.z"..(adxl34x_data.z))
sys.wait(1000)
