 vfd_ctrl.h     -       This file is for VFD controller, All varibles and functions 
                                are HW relative. 
                                1. PANEL_Initial() : Initial VFD controller 
                                2. PANEL_KeyScan() : Panel KeyScan function, include SW Key
                                3. _Hardware_CTRL(): Transfer dispalyram.
                                4. _LightVFD_LED() : Light VFD Led.
                                5. _OutByteVFD()   : Write one BYTE to VFD controller.
                                6. _InByteVFD()    : Read one BYTE key data from VFD controller
