    I'm using two LattePanda 4G/64GB with Windows10.
    One Arduino uses 1.8.10.
    Another Arduino uses 1.0.6. (original)

    I have a problem with Arduino digital output.
    Digital output does not respond even if the following code is executed.
    The operation is the same for both Lattepandas.

    void setup() {
    pinMode(7, OUTPUT);
    digitalWrite(7, LOW);
    }

    void loop() {
    delay(500);
    digitalWrite(7, HIGH);
    delay(500);
    digitalWrite(7, LOW);
    }


    Pin No.7(D7), 9(D9) are NG.
    but, Pin No.10(D10), No.13(D13) are OK.
    No.13's LED is blinking.

    am I forgetting any settings?
