_8154_db51_HSL_D_set_int_renewal_bit
:
This function is used to set the Di data bits of specified modules
that user want to monitor the states.
_8154_db51_HSL_D_set_int_control
:
This function is used to enable or disabel the DI interrupt.
_8154_db51_HSL_D_wait_di_interrupt
:
When user enabled the Interrupt function by
_8154_db51_HSL_D_set_int_control
() and set the renewal
type and data bits on specified slave DI modules by
_8154_db51_HSL_D_set_int_renewal_bit
(),
_8154_db51_
HSL_D_set_int_renewal_type
(). This function can be used to
wait on a specific interrupt. When this function is running, the pro-
cess would never stop until a even is triggered or the function is
time out. The following code is an example.
I16 ret;
_8154_db51_HSL_D_set_int_renewal_type(1, 1);
// slave id = 1, monitor the states of bit 0 and
bit 1
_8154_db51_HSL_D_set_int_renewal_bit(1, 1,
0x003);
_8154_db51_HSL_D_set_int_control(1, 1); //enable
…
// start wait
ret =_8154_db51_HSL_D_wait_di_interrupt(1,
10000);
if(ret == ERR_No_Error)
{ // DI state trainisted and check which bits
change states…
}else
{ // time out
}…
