Modular ESP Firmware - Baseline - Work Environment

platformio.ini

Common settings

 1 [env]
 2 platform = espressif8266
 3 ; For now, let's stick with the 8266 family MCUs
 4 
 5 framework = arduino
 6 
 7 monitor_speed = 115200
 8 ; I like my serial comms fast.  (Without this line you get the default of 9600)
 9 
10 build_flags = -D DEBUG
11 ; This is just plain handy.  You can use it to turn debugging output on/off...

Most ESP8266 Devices

1 [env:esp8266]
2 board = esp07
3 ; Pretty much ANY esp8266 board is an esp07 as far as Platformio is concerned

esp-01

1 [env:esp01]
2 board = esp01

esp-M3

1 [env:espM3]
2 board = esp8285

Notes

You can put as many [env:] sections in as you like & select one at compile-time based on which particular device you're programming.

You'll also be adding other options to the [env:] blocks.

Things like lib_deps come to mind...

build_flags are a good way to customise compiles from a single codebase onto different devices.

For an in-depth set of documentation, see “platformio.ini” (Project Configuration File). You can get pretty involved in this file & do a lot to control how things are built.
