Version 2.05 Date: Jan-8, 2007 Page: 4

1. Introduction

PCI-1202/1602/180x Development Toolkit provides DLL (Dynamic Link Library) and

simple DEMOs. Those DEMOs will show you how easy to use DLL to complete the

I/O process without facing complex hardware.

This document introduces PCI-1202, PCI-1602, and PCI-180x series functions

in the DLL. It is intended to be a companion to know functions, using the special

functions (Continuous Capture, MagicScan...), programming, and error code

information.

These DLL can perform a variety of data acquisition operation as follows:

1. Testing function

2. Plag & Play function

3. DIO function

4. DA function

5. AD funciton

6. MagicScan function

7. M_Function

8. Continuous Capture function

9. Batch Capture function

Section 1.1 : Functions categories and define.

Section 1.2 : Error code define.

Section 1.3 : The list of Configuration code that can control amplifier signal.

Section 1.4 : The list of thread priority setting.

(With the priority setting, you can get higher thread priority in the OS.)

1.1 Function Define

When you read the function manual, please notice the "KeyWORD" for variables.

KeyWORD

functions

Set after call functions and return

value

[Input] Yes No

[Output] No Yes

The functions in the PCI-1202 DLL are divided into 9 categories. (The red WORD

"P1202" of functions name could be replaced with "P1602" or "P180x" to use the

functions which have the same purpose defined in P1602 or P180x DLL.)

wChannel=0 (analog output Channel 0)

wChannel=1 (analog output Channel 1)

wDaVal : [Input] 12 bits data sent to DA port. 0=minimum and 4095=maximum.

The DA output can be +/- 5V or +/- 10V depending on the setting of hardware

JP1. The software can’t detect the state of JP1. So the maximum wDaVal

“4095” may be +5V or +10V

2.5.1 P1202_SetChannelConfig

This subroutine is used to set the AD channel configuration code. (Refer to

section 1.3) It also sets the active AD channel for P1202_AdPolling,

P1202_AdsPolling and P1202_AdsPacer.

*This function will refer to the current active PCI-1202 board. Use the

P1202_ActiveBoard(….) to set the active board.



Syntax :

WORD P1202_SetChannelConfig(WORD wChannel, WORD wConfig);



Parameters :

wChannel : [Input] AD channel number

wConfig : [Input] Configuration code. Refer to "Section 1.3 Configuration Table"



Return :

0 : No Error

Others : Please refer to section 1.2.

2.5.2 P1202_AdPolling

This function will perform a single A/D conversion by software polling. The

P1202_SetChannelConfig function is used to change the active channel and

configuration code that the P1202_AdPolling function using.

*This function will refer to the current active PCI-1202 board. Use the

P1202_ActiveBoard(….) to set the active board.



Syntax :

WORD P1202_AdPolling(float *fAdVal);



Parameter :

*fAdVal :[Output] address of fAdVal which store the AD data, this data is

automatically computed from hexadecimal to float based on the setting of

P1202_SetChannelConfig.
