OME-A-826PG Software Manual [Win 95/98/NT]

3.3.5 A826_Uni5_DA

• Description :

This subroutine will send the 16 bits data to D/A analog output. The output

range of D/A dependent on setting by hardware jumper, JP1 ( -5v or –10v),

JP10/JP11 (Bipolar or Unipolar). The software can not detect the output range

of D/A converter. This subroutine can be used only when the jumpers settings

are : Unipolar , -5v . The output range is between 0.0v and 5.0v. Please refer

to hardware manual to setting jumpers.

• Syntax :

void A826_Uni5_DA(WORD wBase, WORD wChannel, float fValue);

• Parameter :

wBase : [Input] I/O port base address, for example, 0x220

wChannel : [Input] D/A channel number, validate for 0

fValue : [Input] 16 bits data send to D/A converter

• Return Value :

void

3.3.6 A826_Uni10_DA

• Description :

This subroutine will send the 16 bits data to D/A analog output. The output

range of D/A dependent on setting by hardware jumper, JP1 ( -5v or –10v),

JP10/JP11 (Bipolar or Unipolar). The software can not detect the output range

of D/A converter. This subroutine can be used only when the jumpers settings

are: Unipolar , -10v. The output range is between 0.0v and 10.0v. Please

refer to hardware manual to setting jumpers.

• Syntax :

void A826_Uni10_DA(WORD wBase, WORD wChannel, float fValue);

• Parameter :

wBase : [Input] I/O port base address, for example, 0x220

wChannel : [Input] D/A channel number, validate for 0

fValue : [Input] 16 bits data send to D/A converter

• Return Value :

void
