In our, we recommend using the Arduino IDE to program the ESP32 development board. However, in some Windows computers it’s a bit tricky to install the ESP32 add-on using Git GUI due to permission errors, Arduino IDE version, or multiple Arduino IDE installations. There’s also another popular method to program ESP32 development boards using the combined with. With this method you can still use the same programming language you use on Arduino IDE. This next tutorial was tested on a Windows 10 PC and on a Mac OS X computer. Installing Atom Text Editor The first step is to go to website and download the free text editor.
You can download the release versions from Clang is also provided in. From Xcode 4.2, Clang is the default compiler for Mac OS X.
ENROLL IN: After that, open the downloaded installation file and run it. The installation is pretty straightforward. Complete the on-screen instructions to finish the Atom installation. Installing Python 2.7.X on a Windows PC In order to use PlatformIO IDE and program your ESP32 boards, you must have Python 2.7.X installed on your computer. Go to the page and download the latest version of Python 2.7.X for your OS (Operating System).
Note: for this Unit, we’ve used Python 2.7.15. Any other Python 2.7.X version should also work. Open the downloaded file to start the Python installation wizard. During step 2, follow these next instructions:. Scroll down through the “ Customize Python 2.7.15” window;.
Open the “ Add python.exe to Path“;. And select the option “ Will be installed on local hard drive“. After that, press “ Next” button to complete the installation.
After installing Python 2.7.X, you need to open the “ Command Prompt“. DOWNLOAD FREE GUIDE: Run the next sequence of commands to check the Python and pip version installed: python -version Python 2.7.15 pip -version pip 9.0.3 Both commands should return a similar output (the version might be slighter different in your case). After that, check if you have virtualenv installed: virtualenv -version If it’s already installed, you can go to the next section. Otherwise, you need to install it with this command: pip install virtualenv After that, run this command again to check if virtualenv was installed properly: virtualenv -version 16.0.0 2b. Installing Python 2.7.X on Mac OS X In order to use PlatformIO IDE and program your ESP32 boards, you must have Python 2.7.X installed in your computer. Run the next sequence of commands to install Python 2.7.X. Then, check if Python, pip, and virtualenv are installed: $ brew install python2 $ python -version Python 2.7.15 $ pip -version pip 9.0.3 $ virtualenv -version $ pip install virtualenv 3. Installing Clang for Code Completion PlatformIO IDE uses Clang for the Intelligent Code Completion.
To check if Clang is available in your system, open Terminal/Command Prompt and run: clang -version If clang is not installed, then install it by following the instructions for your Operating System:. Windows: download. Select “ Add LLVM to the system PATH” option during the installation step shown in the image below. Warning: DO NOT INSTALL CLANG 4.0, ONLY CLANG 3.9 IS SUPPORTED AT THE MOMENT.
Mac OS X: along with the latest Command Line Tools. They are installed automatically when you run clang in Terminal for the first time, or manually by running: xcode-select -install.
Linux: using package managers: apt-get install clang or yum install clang. Other systems: download the latest. Installing PlatformIO IDE on Atom After installing all the PlatformIO IDE dependencies, open Atom text editor and go to File Settings: On the left menu, open the “ Install” tab: Search for “ platformio” and press the Enter/Return key: Install the “ platformio-ide” option highlighted in the preceding image. After the installation is completed, restart the Atom text editor for the changes to take effect. PlatformIO IDE Overview Now, when you open Atom text editor a new window should load with the “Welcome to PlatformIO” screen: Press the “ New Project” button in the quick access menu: A new window loads that allows you to create a new project for your board, follow these next steps:. Name your project (example: Blink);.
Search for “ ESP32” and select your ESP32 board (example: DOIT ESP32 DEVKIT V1);. Select Arduino framework;.
Press the “ Finish” button. After the new project is created, you’ll see the project folder on the left menu that you can use to navigate through files and folders.
Open the srcfolder and double-click the main.cpp file to open it. A new window opens in Atom with that file, so you can edit it: The main.cpp file is like your Blink.ino file used in the Arduino IDE. You can write your Arduino code, but you need to start with the file by including the Arduino framework. So, basically all the Arduino sketches work with PlatformIO IDE, if you start the sketch with this line following line: #include 6. Testing PlataformIO IDE Let’s try an example to test PlataformIO IDE. We’ll blink an LED connected to GPIO23. Zebra ql420 plus driver for mac. Here’s the list of parts you need to follow this example:.
–. You can use the preceding links or go directly to to find all the parts for your projects at the best price! Follow the next schematic to assemble your circuit.
Here’s a sketch for testing purposes that blinks the LED: Copy the code to the Atom text editor and follow these next steps to upload code to your ESP32 board:. Connect your ESP32 board to your computer;.
Save thew newly created sketch ( File Save);. Press the “ Upload” button (highlighted in the next image).
Wait a few seconds while the sketch uploads to your board: After uploading the sketch, your ESP32 should be blinking the LED attached to GPIO 23 every 1 second. The PlatformIO was successfully installed and you can use it to program your ESP32 board.
PlatformIO IDE Additional Tips We’ve just scratched the surface on what PlatformIO IDE can do. Here’s what each button in the PlatformIO IDE does/means:. PlatformIO Home. PlatformIO Build. PlatformIO Upload.
Upload to remote device. PlatformIO Clean. PlatformIO Test. PlatformIO Debug. Run other target. Toggle Build Panel.
Find in Project. Terminal. Serial Monitor (it’s like the Arduino IDE Serial Monitor).
Download Clang For Mac Pc
Atom Settings We’ve modified the Blink code used previously to include some Serial.println commands to demonstrate how the Serial Monitor looks like. You can open the Serial Monitor by clicking that icon: The PlatformIO software should automatically complete your settings. Otherwise, select your ESP32 COM port and its baudrate. Then, press the “ Start” button: Just like the Arduino IDE Serial Monitor, you have a window that outputs all the Serial.println commands used in your code: As you can see, it’s printing the messages: “LED on” and “LED off”. Wrapping Up We recommend using the following links as a resource to explore the additional functionalities and features that PlaformIO offers:.
