You can check here the source files with the configurations for multiple boards.
Nevertheless, an interesting feature of the ESP32 support for the Arduino IDE is that there are some built in constants that we can use to abstract knowing the mappings between different boards and the ESP32 microcontroller. So, in reality, pin D9 of the FireBeetle board corresponds to pin 2 of the ESP32 microcontroller. Note however that these board pin numbers don’t directly map to the ESP32’s digital pins. Since the pin we are going to control is attached to a LED, then the LED will be on and off as we change the state of the digital pin.Īs we stated before, the on board LED is connected to pin D9. So we will be basically using the Arduino digitalWrite function, which allows us to control if a digital pin is in a HIGH or LOW state. The code for this tutorial will be very simple, since it will be kind of a “Hello World” program using the hardware. Please consult this previous post if you haven’t yet enabled the ESP32 support on the Arduino IDE. This ESP32 board has a built in LED on pin D9, which we will control using a very simple Arduino program. You can learn more about the FireBeetle ESP32 board on this previous tutorial.
BLINK BOARD OR BLINK LITE HOW TO
The objective of this post is to explain how to make the DFRobot’s FireBeetle ESP32 board built in LED blink.
