Counter
Counter panel provides users with pulse signal counting and frequency measurement. You can set the trigger edge and frequency measurement time interval to adapt to different signal characteristics.
Parameter Setting and Operation
Before using the counter function, please confirm your device channel settings and signal source.
caution
Note: Counter function and PWM function share hardware resources, so they cannot be enabled on the same channel at the same time.
Parameter Description
The following parameters can be adjusted in the interface:
| Parameter | Description |
|---|---|
| Counter channel | Select the counter channel to operate (e.g., 0 or 1). |
| Active Edge | Set the signal edge that triggers counting: - Rising: Rising edge trigger - Falling: Falling edge trigger |
| Frequency Window (ms) | Set the time sampling interval (milliseconds) for frequency measurement. The longer the interval, the higher the frequency resolution, but the slower the update speed. |
Control Buttons
Operate the buttons below to control the counting function:
| Button | Function |
|---|---|
| Start | Start counting and frequency measurement. |
| Stop | Stop counting and frequency measurement. |
| Reset | Reset current count value to zero. |
Value Display
After starting, the panel will display the following information in real-time:
- Current Count: The current cumulative count value.
- Current Frequency: The current signal frequency (Hz).
