Re: I keep getting a compiling error on Arduino with ESP8266
Posted: Sat Jul 22, 2017 6:37 pmYou probably first want to compile and upload a simple sketch, like blinking the blue LED on the ESP, before trying larger sketches. 
Code: Select all
#define led_pin BUILTIN_LED // pin 2 on most boards
#define led_interval 500
void setup() {
Serial.begin(115200); // Initialize serial for communication
Serial.setDebugOutput(false); // Turn off WiFi debug messages for now
Serial.print("Setting pin mode of pin ");
Serial.print(led_pin);
Serial.println(" to OUTPUT");
pinMode(led_pin, OUTPUT);
}
void loop() {
Serial.print("Setting pin ");
Serial.print(led_pin);
Serial.println(" to HIGH");
digitalWrite(led_pin, HIGH);
delay(led_interval);
Serial.print("Setting pin ");
Serial.print(led_pin);
Serial.println(" to LOW");
digitalWrite(led_pin, LOW);
delay(led_interval);
}
