Argument:
da_ch_no:
D/A channel number, DA_CH_1 or DA_CH_2.
data:
D/A converted value, if the value is greater
than
4095, the higher 4-bits are negligent.
Return Code:
ERR_NoError
ERR_BoardNoInit
ERR_InvalidDAChannel
Example:
#include “8112.h”
main()
{
_8112_Initial( CARD_1, A8112B_DG, 0x220 );
/* Assume NoError when Initialize ACL-8112 */
/* if the hardware setting for DA output range is
0~5V */
_8112_DA( DA_CH_1 , 0x800 );
printf( "The output voltage of CH1 is 2.5V \n" );
_8112_DA( DA_CH_2 , 0xFFF );
printf( "The output voltage of CH2 is 5V \n" );
}
