ESP32 PlatformIO	Microcontroller development project setup / template	2020-05-03	[tutorial]	hendrik	WTFPL

Install PlatformIO

apt install platformio
platformio platform update

Project setup

Choose your development board from the list. You can see all supported boards with the command: platformio boards espressif32

Now create your new project:

cd ~/Projects/esp32/
mkdir new_project
cd new_project
platformio project init --board esp-wrover-kit

[env:esp-wrover-kit]
platform = espressif32
board = esp-wrover-kit
framework = arduino
monitor_speed = 115200

#build_flags =

/**
 * Blink

 * Turns on an LED on for one second,
 * then off for one second, repeatedly.
 */
#include <Arduino.h>

#ifndef LED_BUILTIN
#define LED_BUILTIN 13
#endif

void setup()
{
  // initialize LED digital pin as an output.
  pinMode(LED_BUILTIN, OUTPUT);
}

void loop()
{
  // turn the LED on (HIGH is the voltage level)
  digitalWrite(LED_BUILTIN, HIGH);

  // wait for a second
  delay(1000);

  // turn the LED off by making the voltage LOW
  digitalWrite(LED_BUILTIN, LOW);

   // wait for a second
  delay(1000);
}

now compile and upload your program

platformio run
platformio run --target upload
platformio device monitor

SPIFFS

mkdir data/

place your files in the directory data/

platformio run --target uploadfs

Git

.gitignore:

.pio

and push to your project on github or gitlab:

touch README.md
git init
git commit -m "first commit"
git remote add origin https://gitlab.com/username/new_project.git
git push -u origin master
