PlatformIO CLI on Linux (Ubuntu 18.04)

Install PlatformIO CLI on Linux (Ubuntu 18.04) for use in programming IOT devices (i.e., ESP8266, ESP32, NodeMCU)

Plus Post Install setup to test the installation (ESP8266 LED blink)

tl;dr

1) Add "export PATH=$PATH:~/.platformio/penv/bin" to .profile in home directory.

2) $ python3 -c "$(curl -fsSL https://raw.githubusercontent.com/platformio/platformio/master/scripts/get-platformio.py)"

3) $ curl -fsSL https://raw.githubusercontent.com/platformio/platformio-core/master/scripts/99-platformio-udev.rules | sudo tee /etc/udev/rules.d/99-platformio-udev.rules

Prerequisites

Python3
curl

Long instructions...

Add a line to .profile in home directory for current user.

Add:
	export PATH=$PATH:~/.platformio/penv/bin


~$ nano .profile
		# ~/.profile: executed by the command interpreter for login shells.
		# This file is not read by bash(1), if ~/.bash_profile or ~/.bash_login
		# exists.
		# see /usr/share/doc/bash/examples/startup-files for examples.
		# the files are located in the bash-doc package.

		# the default umask is set in /etc/profile; for setting the umask
		# for ssh logins, install and configure the libpam-umask package.
		#umask 022

		# if running bash
		if [ -n "$BASH_VERSION" ]; then
		    # include .bashrc if it exists
		    if [ -f "$HOME/.bashrc" ]; then
			. "$HOME/.bashrc"
		    fi
		fi

		# set PATH so it includes user's private bin if it exists
		if [ -d "$HOME/bin" ] ; then
		    PATH="$HOME/bin:$PATH"
		fi

		# set PATH so it includes user's private bin if it exists
		if [ -d "$HOME/.local/bin" ] ; then
		    PATH="$HOME/.local/bin:$PATH"
		fi

▶		export PATH=$PATH:~/.platformio/penv/bin

=> SIDE STEP

At this point it is convenient for the future to make sure your user is in the 'dialout' group so you (user) have permission to access /dev/ttyUSB# devices.

$ sudo usermod -aG dialout {username}

Log out of user and log back in again.

Install PlatformIO CLI (make sure to have python3 >=3.6 installed)

Post Install

For newbies to get started from here and test the installation:

If you have an IOT device to connect, now is a good time (I like to use the following steps).

$ watch lsusb
        Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
        Bus 001 Device 004: ID 8087:0a2a Intel Corp. 
        Bus 001 Device 034: ID 258a:1007  
        Bus 001 Device 033: ID 1a40:0101 Terminus Technology Inc. Hub
        Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Plug in USB device (i.e, NodeMCU, ESP32, etc)
Something like this should appear in the list.

	Bus 001 Device 028: ID 10c4:ea60 Cygnal Integrated Products, Inc. CP210x UART Bridge / myAVR mySmartUSB light

In my board's case, it is using a CP210x UART Bridge which happens
to be the first entry in our 99-platformio-udev.rules file
we had added earlier.

$ pio device list

	******************************************************************************************
	We found 2.06MB of unnecessary PlatformIO system data (temporary files, unnecessary packages, etc.).
	Use `pio system prune --dry-run` to list them or `pio system prune` to save disk space.

So, my board was assigned the /dev/ttyUSB0 device for communication, yay.

Now to create a PlatformIO project (in my case, have the ESP8266 blink
its onboard LED)


$ mkdir ~/esp8266/blink
$ cd ~/esp8266/blink
$ pio project init
        The current working directory /home/scotty/esp/testing will be used for the project.

        The next files/directories have been created in /home/scotty/esp/testing
        include - Put project header files here
        lib - Put here project specific (private) libraries
        src - Put project source files here
        platformio.ini - Project Configuration File

        Project has been successfully initialized! Useful commands:
        `pio run` - process/build project from the current directory
        `pio run --target upload` or `pio run -t upload` - upload firmware to a target
        `pio run --target clean` - clean project (remove compiled files)
        `pio run --help` - additional information

Now update the platformio.ini file:

; PlatformIO Project Configuration File
;
;   Build options: build flags, source filter
;   Upload options: custom upload port, speed and extra flags
;   Library options: dependencies, extra library storages
;   Advanced options: extra scripting
;
; Please visit documentation for the other options and examples
; https://docs.platformio.org/page/projectconf.html

[env:latest_stable]
framework = arduino
platform = espressif8266
board = nodemcuv2

monitor_port = /dev/ttyUSB0
upload_speed = 921600 ; increased upload time from ~17 to ~3 secs.

And create a main.cpp file in src directory:

#include "Arduino.h"

void setup() {
  pinMode(LED_BUILTIN, OUTPUT);     // Initialize the LED_BUILTIN pin as an output
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(LED_BUILTIN, HIGH);   // Turn the LED on (Note that LOW is the voltage level
                                    // but actually the LED is on; this is because 
                                    // it is acive low on the ESP-01)
  delay(1000);                      // Wait for a second
  digitalWrite(LED_BUILTIN, LOW);  // Turn the LED off by making the voltage HIGH
  delay(2000);                      // Wait for two seconds (to demonstrate the active low LED)
}

So in my project folder (~/esp8266/blink) I have:

.gitignore
include/
lib/
.pio/
platformio.ini
src/
  |_ main.cpp
test/

Now to compile and upload to the board and hopefully see A little LED blinking:

../blink$ pio run --target upload

Ah, I see a little LED on the ESP-12E component of the board blinking!  Yay.

And now, to attach a little OLED screen to the ESP8266 and display a little R2D2 image...AHHH...it's just too fun...

Seriously though I did do that here.
