| Abstract: | In order to reduce design complexity introduced by the variety of hardware used in embedded systems,this paper presents how to use the Hardware Abstraction Layer(HAL) provided by open source motion control software EMC2 to construct the HAL drive for CNC system.The structure and principle of HAL are introduced.An example of how to use HAL in soft PLC software ClassicLadder is given.Practice shows that HAL has effectively improved the expandability and portability of software and hardware in the system. |
