Tutorial - First Time Use

Arduino IDE Configuration

Please pay attention to the followings when using FireBeetle 2 ESP32-S3 for the first time.

1. Add the json link in the IDE
2. Download the core of the MCU
3. Select the development board and serial port
4. Open the sample code and burn it into the board
5. Get to know the serial monitor

Arduino IDE compiler environment config

• Configure URL to the Arduino IDE

1. Open Arduino IDE and click File->Preferences, as shown below.

2. In the newly opened interface, click the button in the red circle as shown below

3. Copy the following link into the new pop-up dialog box: https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json

Note: If you have installed another environment before, you can press Enter key at the beginning or end of the previous link and paste the link at a new line.

4. Click OK. Update the board. Open Tools->Board:->Boards Manager... as shown below：

   

5. Boards Manager will automatically update the boards as shown below:

   

6. After completing the update, you can enter esp32 at the top, select esp32 and click install when the following occurs (It's recommended to install the latest version):

   

7. Wait for the end of the following progress bar:

   

8. After completing the installation, the list will show that the esp32 has been installed, as shown below:

   

9. Click Tools->Board, select DFRobot FireBeetle 2 ESP32-S3.

10. Before starting, you need to configure the following settings (when you select Disabled, the serial port is RX(44), TX(43), if you need to print on the Arduino monitor via USB, you need to select Enable)

11. Click Port to select the corresponding serial port.

5.2 LED Blinking

The default pin for the onboard LED is pin 12.

Sample Code

int led = 21;
void setup() {
pinMode(led,OUTPUT);
}

void loop() {
digitalWrite(led,HIGH);
delay(1000);
digitalWrite(led,LOW);
delay(1000);
}

• Copy the codes above to the code editing box.
• Click the arrow to complile the program and burn it into your development board.

Burning Successful

The image above shows that your codes have been successfully loaded into the board. Then, the onboard LED will start blinking.

• Burning failed? Click here.

Tutorial for MicroPython

Build Environment for MicroPython

To run microPython on the FireBeetle 2 ESP32-S3, you need to burn the firmware into FireBeetle 2 ESP32-S3 first.

1.Click to download microPython firmware

2.Click to download esptool Flash burning tool

3.Run flash_download_tool_3.9.3.exe

4.Select the ESP32-S3 main controller, than Press Boot, press RST and release both, then try burning again.

5.Select the downloaded firmware, clear the flash and then burn the firmware.

MicroPython Interpreter

1.Click to download thonny

2.Open the software and set up the interpreter (Run->Configure interpreter...)

3.Copy and paste the code into the code box, save the file to the MicroPython device and name it main.py

import time
from machine import Pin

led=Pin(21,Pin.OUT)

while True:

led.value(1)
time.sleep(1)
led.value(0)
time.sleep(1)

4.Reboot the FireBeetle 2 ESP32-S3, and you can see the L LED flashing.

FAQ

1. What will cause burning error?

• There is no delay or too short delay in Loop.

• The USB cannot be recognized by the PC as some functions are incorrectlly called.

  

How to solve

• Press Boot, press RST and release both, then try burning again.

2. Data cannot be printed on serial port

• Check if the USB CDC is enabled
• Check print information using other serial debugger.
