Getting Started With ESP32 on a Mac: Blink and LED

Introduction: Getting Started With ESP32 on a Mac: Blink and LED

The ESP32 development board is super-charged version of the popular ESP8266. It is a WiFi-compatible microcontroller, in addition to having Bluetooth low-energy (BLE4.0) and 27 I/O pins. It also has a very small form factor relative to the Arduino and is also very cheap, approximately $5, making it the ultimate prototyping micro control. Since it has both WiFi and Bluetooth it is a great device to be used for Internet of Things (IoT) devices and projects.

This project is an introductory lesson in the use of the ESP32 in a series of tutorials for a variety of use cases and projects for the ESP32 development board, ranging from simple sensor interfacing to IoT devices.

I am inspired to write this instructable since I could not find a decent guides regarding how to get started with the use of the ESP32 Development Board. It is such a powerful board for it’s size and price that I believe people should be more aware of it’s existence and use.

Step 1: Tools and Materials

• 2 Breadboards
• ESP32 Development Board
• 5mm Red LED
• 100Ω Resistor
• USB to micro-usb cable

Step 2: Installing the ESP32-Arduino-ACore Firmware

Natively, the Arduino IDE does not support the ESP32 Development board. Thus, the option to use the ESP32 will not be visible until the firmware is properly installed and that the Arduino IDE has been restarted.

1. Open the Terminal and enter the following lines of code.

2. Press enter and let the code run.

3. Restart the Arduino IDE and the you will see the ESP32 appear in the Tools>>Board

Step 3: Install the SiLabs Driver

The ESP32 Development board’s ports will not be recognized by the Arduino IDE since there are several drivers that are missing on a Mac.

1. Download the drivers through the SiLabs website: https://www.silabs.com/Support%20Documents/Softwar.
2. Install the drivers onto the computer
3. Plug in the ESP32 through the micro-usb cable to the computer, and the port will appear on the Arduino IDE under Tools>>Ports.

Step 4: Plugging in the ESP32 Development Board

The ESP32 board is larger than its predecessor the ESP8266 as such it has to fit in between two breadboard to be usable.

1. Tape two breadboards together.
2. Plug in the ESP32 Development board in between the two breadboards.

Step 5: Wiring the Circuit

1. Connect the 100Ωresistor to the pin called D6 on the ESP32.
2. Connect the Anode of the LED to the end of the 100Ωresistor.
3. Connect the Cathode of the LED to the pin called GND on the ESP32.

Step 6: Coding

The code is relatively similar to that of the Arduino and are both written in C. However, there are differences in the baud rate as shown below.

Step 7: LED Blinking Demonstration

The LED blinking demonstration is the same result as the Arduino, but with the use of a much smaller form factor.

I have tried just about everything, but can NOT get a ‘COM’ port to appear in the menu. I am using Arduino IDE 1.8.9 on a Mac Mojave 10.14.6 (USB 3.0) and a HiLetgo ESP-WROOM-32 ESP32 ESP-32S Development Board. Everything in this instructable was run without error. Any help would be greatly appreciated.

Установка, прошивка платы ESP32 в Arduino IDE (Windows, Mac OS X, Linux)

Существует надстройка для Arduino IDE, которая позволяет программировать ESP32 с использованием Arduino IDE и его языка программирования. В этой статье мы покажем вам, как установить плату ESP32 в Arduino IDE, не зависимо от используемой вами операционной системы: Windows, Mac OS X или Linux.

Если у вас возникли какие-либо проблемы во время процедуры установки, сообщите об этом на форуме.

Необходимые условия: Arduino IDE последней версии.
Перед началом установки убедитесь,что на вашем компьютере установлена последняя версия Arduino IDE. Если у вас стоит не последняя версия, сперва удалите текущую версию и затем установите более новую версию. В противном случае, данная инструкция может не сработать.
Имея последнюю версию Arduino IDE, установленную с официального сайта, продолжайте установку по данной инструкции.

Установка дополнения ESP32 в Arduino IDE

Чтобы установить плату ESP32 в Arduino IDE, выполните следующие действия:
1. В вашем Arduino IDE перейдите в Файл> Настройки

2. Войдите https://dl.espressif.com/dl/package_esp32_index.json. в поле «Дополнительные ссылки для менеджера платы», как показано на рисунке ниже. Затем нажмите кнопку OK.

Внимание: Если вы у вас установлена в Arduino IDE ESP8266 то добавьте 2 строки или через запятую:

3. Откройте Менеджер плат. Перейдите в меню Инструменты > Платы > Менеджер плат

4. Ищем ESP32. И нажимаем кнопку Установка.

5. Вот и все. Через пару минут у вас все установиться.

Первая загрузка скетча в ESP32.

Подключите плату ESP32 к компьютеру. Открываем Arduino IDE и выполним следующие действия:

1. Выберите доску в меню Инструменты > Плата (в моем случае это DOIT ESP32 DEVKIT V1 )

Плата (в моем случае это DOIT ESP32 DEVKIT V1)» width=»382″ height=»240″ style=»display: block; margin: auto; width: 382px; height: 240px;» rel=»display: block; margin: auto; width: 382px; height: 240px;»>

2. Выберите порт (если вы не видите COM-порт в Arduino IDE, вам необходимо установить драйверы CP210x USB to UART Bridge VCP). В моем случае ком порт отображается по другому. Это связанно с тем что я использую OS Linux.

3. Открыть в следующем примере в Файл > Примеры > WiFi > WiFiScan

4. В вашей среде Arduino IDE откроется новый скетч.

5. Нажмите кнопку Загрузить в Arduino IDE. Подождите несколько секунд, пока код компилируется и загружается на вашу плату.

Внимание! Если у вас бежит строка с повторяющимися точками и линиями. Нажмите кнопку Boot на плате и удерживайте ее пока не побегут проценты загрузки. После чего кнопку можно отпустить.

6. Откройте последовательный монитор Arduino IDE со скоростью передачи данных 115200.

7. Нажмите кнопку EN на борту ESP32 , и вы увидите список сетей, доступных для вашей ESP32.

Подведение итогов.
Это краткое руководство, которое иллюстрирует, как подготовить ваш Arduino IDE для ESP32 на компьютере с ОС Windows, Mac OS X или Linux. Если во время установки возникнут какие-либо проблемы, пишите на форум.

Теперь вы можете начать создавать свои собственные проекты IoT с ESP32.

ESP32. Getting started with ESP32-Arduino on IDE Arduino, macOS, Windows, Linux

The ESP-Arduino development kit (for Espressif IoT Development Framework) for the Arduino IDE allows to develop code for all development boards based on ESP32. It provides access to most of the functions of the ESP-IDF library. It is very easy to install from the library manager of the Arduino IDE. It is also possible to use the ESP-IDF framework from the command line from the Terminal (macOS or Linux) and PowerShell (Windows).

The Espresso Development Kit (SDK) for ESP32 boards is available on GitHub . It is compatible with the Arduino IDE for macOS, Windows, Linux 32-bit, 64-bit and ARM chips (Raspberry Pi, Orange Pi, etc …). Very detailed documentation is available here .

Install the ESP32-Arduino Framework for ESP32 on the Arduino IDE

Now that the ESP-IDF framework for ESP32 development boards is directly available from the board manager of the Arduino IDE, the installation procedure is the same whatever the operating system (Windows 10, macOS, Linux, Raspberry Pi OS , Armbian…)

1 Open the preferences panel from the Arduino menu

2 click the button to the right of the Additional board manager URL option .

3 In the dialog box that opens, add the link below and click OK

There is also a link to the version under development (release). This version is not recommended for production. It makes it possible to evaluate the new functionalities under development.

4 The link to the repository is added to the list. Close the settings by clicking on OK

5 Open the board manager from the Tools menu then Card type

6 Search for the SDK with the keyword ESP32. Choose the board package named ESP32 by Espressif Systems then click on install.

Wait for the framework to be downloaded and installed from the internet. The installation process is fully automated. There is absolutely nothing more can be done.
