Bean
EventCntr8
|
Event counter 8-bit
Parameters of the bean.
|
Properties:
-
Bean name - Name of the bean.
-
Counter - Counter register of the timer.
-
Interrupt service/event - Bean uses the interrupt service for the counter function.
-
Interrupt - Interrupt vector invoked from the timer (for information only).
-
Interrupt priority - Priority of the interrupt associated with the timer.
-
Event - Event settings.
-
Counter input pin - Counter external clock pin.
-
Input pin signal - Signal name of input pin.
-
Pull resistor - Setting of pull resistor.
There are 6 options:
- no pull resistor: Input without pull resistor is required
- pull up: Input with pull-up resistor is required
- pull down: Input with pull-down resistor is required
- pull up or no pull: Input with pull-up resistor is preferred, but no-pull is acceptable
- pull down or no pull: Input with pull-down resistor is preferred, but no-pull is acceptable
- autoselected pull: There are no special requirements for pull resistors
-
Settings no supported for HC08 only.
-
Edge - Type of signal edges that are counted.
There are 4 options:
- rising or falling edge: One of the following edge type will be selected: rising or falling
- rising edge: Rising edge required
- falling edge: Falling edge required
- both edges: Both edges (rising and falling) required
-
Initialization - Initial settings (after power-on or reset).
-
The following items are visible only if integration of Processor Expert with Simulink supported.
-
Bean name - Name of the bean.
-
Edge - Type of signal edges that are counted.
There are 4 options:
- rising or falling edge: One of the following edge type will be selected: rising or falling
- rising edge: Rising edge required
- falling edge: Falling edge required
- both edges: Both edges (rising and falling) required
-
Mode - Counting mode.
Simple counter - counter counts up to 256 cycles and then overflows. Repetitive - counter counts to a given number of cycles and after that it invokes OnEnd user event.
-
Iterations before action - Number of cycles to invoke the OnEnd event. (Property is only available when the bean is in Repetitive mode)
