  • The GPIO of Fireduino will not be able to select the pull up and down when input,its built-in have fixed the up and down direction,if you need to turn on this function,can according to the following table configuration pull function of GPIO,and you can continue to use the configuration method of Arduino to configuration pull up and down,its actual function is for pull function of GPIO.

                                        • GPIO pull direction

PIN Sliding direction PIN Sliding direction PIN Sliding direction PIN Sliding direction
0 pull up 8 pull down 14 pull up 23 pull up

  • Analog pin (A0~A7) of Fireduino can't be used as digital pins,only can be used in the ADC data acquisition,and analog input voltage must be less than the reference voltage of 2.55V.The reference voltage of Fireduino is not available,the fixed at 2.55V.

  • All analog pins of Fireduino can be used as PWM output pin,for the software timer implementation,there will be some small deviation (< 1%).The PWM duty cycle the adjusting range of 0~255,the frequency of 556Hz.

  • External interrupt,trigger mode of Fireduino also have four,but four patterns for low level trigger,high level trigger,rising edge and falling edge trigger,there is no level change triggered interrupt options.
