VXC-182i 0xe159 0x0001 0x0161 0x0001 0x00
All necessary functions are provided as follows:
1. PIO_DriverInit(&wBoard, wSubVendor, wSubDevice, wSubAux)
2. PIO_GetConfigAddressSpace(wBoardNo,*wBase,*wIrq, *wSubVendor,
*wSubDevice, *wSubAux, *wSlotBus, *wSlotDevice)
3. Show_PIO_PISO(wSubVendor, wSubDevice, wSubAux)
All functions are defined in PIO.H. The important driver information is as follows:
1. Resource-allocated information:
•
