This function is only available for C/C++ and Pascal for DOS.
1) i_APCI1500_SetBoardIntRoutineDos (..)
Syntax:
<Return value> = i_APCI1500_SetBoardIntRoutineDos
(BYTE
b_BoardHandle,
VOID
v_FunctionName
(BYTE
b_BoardHandle,
BYTE
b_InterruptMask
BYTE
b_InputChannelNbr))
Parameters:
- Input:
BYTE
b_BoardHandle
Handle of board
xPCI-1500
VOID
v_FunctionName
Name of the user interrupt routine
- Output:
No output has occurred.
Task:
This function must be called up for each
xPCI-1500
on which an interrupt
action is to be enabled. It installs an user interrupt function in all boards on
which an interrupt is to be enabled.
First calling (first board):
- the user interrupt routine is installed
- interrupts are enabled.
If you operate several boards
xPCI-1500
which have to react to interrupts, call
up the function as often as you operate boards
xPCI-1500
. The variable
v_FunctionName
is only relevant
for the first calling
.
From the second call of the function (next board):
- interrupts are enabled. The first board can receive IRQ.
Interrupt
The user interrupt routine is called up by the system when an interrupt is
generated.
An interrupt is generated when:
- the counter/timer has run down
- an event is generated
- the watchdog has run down
