Function Parameters

Name	Description
board	The handle of the board to operate on
config_bytes	The value(s) used to configure the digital I/O ports. See each board's user manual for information on the number and definition of the configuration bytes.

Return Value

Usage Example

The following code example configures digital I/O direction on a Garnet MM-48. See the Garnet user manual for more information.

    ERRPARAMS errparams;
    BYTE config_bytes[2];

    config_bytes[0] = 0x9b;  // Set all ports on first chip to input
    config_bytes[1] = 0x80;  // Set all ports on second chip to output

    if ((result = dscDIOSetConfig(dscb, config_bytes)) != DE_NONE)
    {
        dscGetLastError(&errparams);
        fprintf(stderr, "dscDIOSetConfig failed: %s (%s)\n", 
                dscGetErrorString(result), errparams.errstring);
        return result;
    }
