Why doesn't my GPIO pin stay high below 200 Hz in my frequency counter code?
The frequency counter might not be reading consistently at lower frequencies.add a small debounce delay or hysteresis to stabilize the pin state. The UART code likely isn't affecting this, but if unused, you can comment it out or disable UART in the initialization code to avoid resource conflicts. For PA0 not working, ensure it's not reserved for other functions, like input capture.
