Hi!
I try use ESP8266 with GPIO6-11.
I use pinMode (9, FUNCTION_3); (or I tryed Function_4), but not work. Why?
// the setup function runs once when you press reset or power the board
void setup() {
// initialize digital pin LED_BUILTIN as an output.
pinMode (6, FUNCTION_3);
pinMode(6, OUTPUT);
pinMode (7, FUNCTION_3);
pinMode(7, OUTPUT);
pinMode (8, FUNCTION_3);
pinMode(8, OUTPUT);
pinMode (9, FUNCTION_3);
pinMode(9, OUTPUT);
pinMode (10, FUNCTION_3);
pinMode(10, OUTPUT);
pinMode (11, FUNCTION_3);
pinMode(11, OUTPUT);
pinMode(2, OUTPUT); //built in led
}
// the loop function runs over and over again forever
void loop() {
digitalWrite(11, HIGH); // turn the LED on (HIGH is the voltage level)
digitalWrite(2, HIGH);
delay(1000); // wait for a second
digitalWrite(11, LOW); // turn the LED off by making the voltage LOW
digitalWrite(2, LOW);
delay(1000); // wait for a second
}
