5.7 _8216_DA

@Description

This function is used to write data to D/A converters. There are two

Digital-to-Analog conversion channels on the ACL-8216. The

resolution of each channel is 12-bit, i.e. the range is from 0 to 4095.

@ Syntax

int _8216_DA(int da_ch_no, unsigned int data )

@ Argument

da_ch_no:

D/A channel number

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 "8216.h"

main()

{

_8216_Initial( CARD_1, 0x220 );

/* Assume NoError when Initialize ACL-8216 */

/* If the hardware setting for DA output is 0~5V

_8216_DA( CH_1 , 0x800 );

printf( "The output voltage of CH1 is 2.5V.\n" );

_8216_DA( CH_2 , 0xFFF );

printf( " The output voltage of CH2 is 5V.\n" );

}
