Description
This block reads the value of a frequency input. Some modules also support duty cycle measurement and/or edge count measurement through this input. Support of duty cycle and edge-count measurement is hardware-specific (if parameters to enable ports for these features don't appear in the block mask, these features are not supported by the module).
Outputs
| Output | Type | Description |
|---|---|---|
| Frequency Input | uint32 | The frequency of the selected input in 0.01Hz. For example, a raw value of 1000 = 10Hz |
| Duty Cycle | uint16 | The duty cycle of the selected input in 0.01%. For example, a raw value of 5000 = 50% duty cycle. |
| Edge Count | uint32 | The number of edges detected on the selected input since the previous time this block was triggered. |
Parameters
| Parameter | Type | Description |
|---|---|---|
| Hardware Resource | Specifies which input from the hardware is being read. | |
| Pull Up/Down | Specifies pull up/down resistor for input on modules which support this function. | |
| Duty Cycle Measurement | Enables duty cycle measurement on inputs and modules which support this function. | |
| Edge Count | Checkbox | Enables edge count measurement on inputs and modules which support this function. |
