    GPIO pin max current


      I want to connect a LED to GPIO Pin. The LED brightness is controlled using PWM signal. LED specifications are

      Vf = 3.3v

      If = 20mA

      Vr= 5V

      Ir = 2uA

      Do I have to connect any resistor or LED driver?

      what is the max current I can get from GPIO pins of FX3.
