    CYBLE-214015-01 - MODE HIGH IMPEDIANCE/ OPEN DRAIN

    AdRa_4011776

      We are using the CYBLE-214015-01 microcontroller, in one of its pins we configure it as "High Impediance Analog" or "Open Drain" and connect it to an LED, the power of the microcontroller is 2.5V, and for the LED it is 5V Then according to the configuration that we have adjusted when a 1 or 0 is sent to the pin output, it should be floating, that is, the LED should be completely off or on depending on the configured mode, but it happens that when we want to turn off the LED (with any of the settings), it remains illuminated. Could someone explain to me why this happens?
