PA 1500
BYTE b_HardwareOrSoftwareGateSelect
- PA1500_HARDWARE_GATE: Input
16 is used for the gate.
- PA1500_SOFTWARE_GATE: Input
16 has no influence on the gate.
BYTE b_InterruptHandling
Interrupts can be generated, when the
counter or watchdog has run down.
With this parameter the user decides to
use interrupts or not.
- PA1500_ENABLE: Interrupts are
enabled.
- PA1500_DISABLE: Interrupts are
disabled.
Task:
Selects the operating mode of the third counter/watchdog. Enter its limit.
You have to decide:
-
if the counter must execute once or several times the counting operation.
-
if the counter/watchdog is used as a counter or a watchdog
-
if an interrupt must be generated when the counter/watchdog has run
down.
-
and if the external gate is used (if it is used as a counter).
Return value:
0: No error
-1: The handle parameter of the board is wrong
-2: The parameter for selecting the counter or the timer is wrong
(PA1500_COUNTER or PA1500_WATCHDOG)
-3: Interrupt selection error (PA1500_ENABLE or PA1500_DISABLE)
-4: User interrupt routine is not installed
-5: Cycle parameter is wrong
(PA1500_CONTINUOUS or PA1500_SINGLE)
-6: Gate parameter is wrong
(PA1500_SOFTWARE_GATE or PA1500_HARDWARE_GATE)
