Datasheet

You don't have to set Programmer because it will always use the serial port, just ignore that menu item!

Blink Test

We'll begin with the simple blink test

Enter this into the sketch window (and save since you'll have to)

Now you'll need to put the board into bootload mode. You'll have to do this before each upload. There is no timeout for

bootload mode, so you don't have to rush!

1. Hold down the GPIO0 button, the red LED will be lit

2. While holding down GPIO0, click the RESET button

3. Release RESET, then release GPIO0

4. When you release the RESET button, the red LED will be lit dimly, this means it's ready to bootload

Once the ESP board is in bootload mode, upload the sketch via the IDE

void setup() {

pinMode(0, OUTPUT);

}

void loop() {

digitalWrite(0, HIGH);

delay(500);

digitalWrite(0, LOW);

delay(500);

}
