Function Documentation

Button_IsPressed()

bool Button_IsPressed

(

void

)

Read the K1 user button state.

Returns

true if the button is currently held down (pin sampled low after the active-low conversion), false otherwise.

Note

Pure read — no debounce, no edge detection. Callers that care about transitions should sample twice with a short delay between reads or maintain their own previous-state flag.

Safe to call from any task context. Does not enter a critical section.
