  • Page 27: Introduction

    Below, the individual calls of the program interface will be described. The prototypes of the calls and the required constants are in the header file ‘io72api.h’. When using the CPCI-DIO72 board, the header file must always be integrated into the source code. Write and read accesses into registers of the CPCI- DIO72 board are generally 32 bits wide.

    BUFFER_SIZE ,BUFFER_COUNT); The advantage of io72MultiDma-functions compared to the io72DmaRead- function is that all input data are stored after io72MultiDmaStart has been called, until io72MultiDmaStop is called.

  • Page 42: Io72Multidmaread()

    Description of Functions io72MultiDmaRead() Name: io72MultiDmaRead() - Reading inputs of the CPCI-DIO72-board via DMA Call: io72MultiDmaRead HANDLE hnd, void *buffer Description: This function blocks until a buffer area which has been designed for this by io72MultiDmaStart is filled with data. If this is the case, a pointer pointing to the beginning of this filled buffer area is returned at the position pointed to by buffer.

  • Page 43: Io72Multidmastop()

    Call: io72MultiDmaStop HANDLE Description: By calling this function a DMA-transfer which was started by means of io72MultiDmaStart is stopped. The handle of a CPCI-DIO72-board is specified to this function via hnd. Specification: *hnd: Handle which was returned by io72Open.

    ENOMEN The buffer cannot be allocated. EBUSY The function cannot run because a resource on the CPCI-DIO72 is already used (e.g.: a DMA-transfer is active). Table 3.7: Returned values and error codes CPCI-DIO72 Software Manual Rev. 1.5 - esd gmbh...

  • Page 49: Operation Of Multi-Dma-Calls

    The io72MultiDma. . . - calls can automatically fill various memory areas successively with reading data without the need of starting another DMA-transfer from the programming code. The driver uses the scatter-gather-DMA-mode of the PCI9054 bridge on the CPCI-DIO72 board for these functions. By means of the API-call io72MultiDmaStart various data structures are constructed and initialised first.
  • Page 50 As soon as the entire list has been worked off, the process proceeds with the beginning of the list again (chain structure). This procedure can be aborted any time by calling io72MultiDmaStop. The capacity of these API-calls is the indepent processing of the scatter-gather-descriptor list by means of the PCI- bridge.

    In the second part of the routine a second task is started, which created several edges in the inputs after a short delay. These edges trigger interrupts which the first task is waiting for. The edge capture register is returned at the end of this test. CPCI-DIO72 Software Manual Rev. 1.5 - esd gmbh...

    This test demonstrates the way the io72MaskWrite-calls of the programming interface are working. Writing accesses in the routine always only mainpulate the bit positions which have been enabled for this by masking data. CPCI-DIO72 Software Manual Rev. 1.5 - esd gmbh...
