| + | ===== Description ===== | ||
| + | \\ | ||
| + | The Toggle Counter cell counts the number of edges seen on its input pin and outputs the count as a 32.0 integer value. The toggle detection can be set to detect rising or falling edges on the input. | ||
| + | \\ | ||
| + | ===== Usage ===== | ||
| + | \\ | ||
| + | The toggle counter increments an internal counter each time an edge is detected on the input. Two algorithms exist: one for detecting and counting rising edges, and one for detecting and counting falling edges. | ||
| + | |||
| + | The rising edge counter starts at zero when the program begins. Each time the input detects a rising edge - in any number format - the counter will increment. After the counter exceeds the maximum count value (which can be configured in the GUI), it will reset to zero and resume counting again. | ||
| + | |||
| + | The falling edge counter starts at zero when the program begins. Each time the input detects a falling edge - in any number format - the counter will increment. After the counter exceeds the maximum count value (which can be configured in the GUI), it will reset to zero and resume counting again. | ||
