Description

Declaration

Arguments

typedef struct  iodbpi {
    short datano_s; /* start number of pitch error data */
    short dummy;    /* (not used) */
    short datano_e; /* end number of pitch error data */
    char  data[N];  /* pitch error compensation data */
} IODBPI ;          /* N : number of pitch error data */

Return

EW_OK is returned on successful completion, otherwise any value except EW_OK is returned.

The major error codes are as follows.

As for the other return codes or the details, see "Return status of Data window function"

CNC option

This function need the following CNC option.

The pitch error compensation option.

And this function is related to the following CNC option.

Bi-directional pitch error compensation
Extended bi-directional pitch error compensation

For HSSB connection,

The extended driver/library function is necessary.

For Ethernet connection,

The Ethernet function and the extended driver/library function are necessary.

However, in case of Series 16i/18i/21i-B, 0i-B/C/D/F, Series 30i and PMi-A, the required CNC option is as follows.

When Embedded Ethernet is used,

above two optional functions are not required.

When Ethernet board is used,

only Ethernet function is required.

CNC parameter

This function is related to the following CNC parameter.
See the manual of CNC parameter for details.

When you use the Bi-directional pitch error compensation : No.3605#0

CNC mode

This function can be used in any CNC mode.

Available CNC

Note) 0i-C does not support the HSSB function.

Example(C Language)

 
The following program writes the pitch error compensation data within the
specified number range.

#include "fwlib32.h"

/* start/end are start/end number to be written. */
/* data is array of value to be written. */
short example( short start, short end, char *data )
{
    IODBPI *pitch ;
    short ret, idx ;
    pitch = (IODBPI *)malloc( 1024 ) ;
    pitch->datano_s = start ;
    pitch->datano_e = end ;
    for ( idx = 0 ; idx < end-start+1 ; idx++ )
        pitch->data[idx] = data[idx] ;
    ret = cnc_wrpitchr( h, 6+(end-start+1), pitch ) ;
    free( pitch ) ;
    return ( ret ) ;
}
 

Example(C#)

The following program writes the pitch error compensation data within the
specified number range.

class example
{
    /* start/end are start/end number to be written. */
    /* data is array of value to be written. */
    public short sample(short start, short end, sbyte[] data)
    {
        Focas1.IODBPI pitHead = new Focas1.IODBPI();
        short ret, idx;

        byte[] bytes = new byte[1024];
        IntPtr ptrHead = Marshal.AllocCoTaskMem(Marshal.SizeOf(pitHead));

        pitHead.datano_s = start;
        pitHead.datano_e = end;
        Marshal.StructureToPtr(pitHead, ptrHead, false);
        Marshal.Copy(ptrHead, bytes, 0, 6);
        for (idx = 0; idx < end - start + 1; idx++)
        {
            bytes[6 + idx] = (byte)data[idx];
        }
        ret = Focas1.cnc_wrpitchr(h, (short)(6 + (end - start + 1)), bytes);
        Marshal.FreeCoTaskMem(ptrHead);
        return (ret);
    }
