Example

--Note: due to the use of sys.wait() all apis need to be used in the coroutine
-- Usage Examples
local sc7a20 = require "sc7a20"
i2cid = 0
i2c_speed = i2c.FAST
sys.taskInit(function()
    i2c.setup(i2cid,i2c_speed)
    sc7a20.init(i2cid)--initialization, passing in i2c_id
    while 1 do
        local sc7a20_data = sc7a20.get_data()
        log.info("sc7a20_data", "sc7a20_data.x"..(sc7a20_data.x),"sc7a20_data.y"..(sc7a20_data.y),"sc7a20_data.z"..(sc7a20_data.z))
        sys.wait(1000)
    end
end)
