5.27 _7200_DI_Timer

@ Description

This function is used to set the internal timer pacer for digital input. There are two configurations for the internal timer pacer:

1. Non-cascaded (One COUNTER 0 only)

8254 Timer/Counter

4MHz Input

CLK0Counter 0

GATE0OUT0

Digital Input Trigg

Timer pacer frequency = 4Mhz / C0

2. Cascaded (TIME2 cascaded with COUNTER0)

8254 Timer/Counter

CLK0Counter 0

GATE0OUT0

Counter 1

CLK1

GATE1 OUT1

4MHz Input

Counter 2

CLK2

GATE2 OUT2

Digital Input Trigg

Timer pacer frequency = 4Mhz / (C0 * C2)

@ Syntax

Visual C++ (Windows 95)

int W_7200_DI_Timer (U16 c0, U16 c2, Boolean mode)

Visual Basic (Windows 95)

W_7200_DI_Timer ( ByVal c0 As Integer, ByVal c2 As Integer, ByVal mode As Byte ) As Long

C/C++ (DOS)

int _7200_DI_Timer (U16 c0, U16 c2, Boolean mode)

@ Argument

c0: frequency divider of Counter #0. Valid value ranges from 2 to 65535.

c2: frequency divider of Counter #2. Valid value ranges from 2 to 65535.

Note: Since the Integer type in Visual Basic is a signed integer. Its range is within -32768 and 32767. In Visual Basic, to set c0 or c2 to a value larger than 32767, set it as the intended value minus 65536. For example, to set c0 as 40000, set c0 as 40000-65536=-25536.
