Modular ESP Firmware - Baseline - Work Environment

platformio.ini

Most ESP8266 Devices

 1 [env:esp8266]
 2 platform = espressif8266
 3 ; For now, let's stick with the 8266 family MCUs
 4 
 5 board = esp07
 6 ; Pretty much ANY esp8266 board is an esp07 as far as Platformio is concerned
 7 
 8 framework = arduino
 9 
10 monitor_speed = 115200
11 ; I like my serial comms fast.  (Without this line you get the default of 9600)
12 
13 build_flags = -D DEBUG
14 ; This is just plain handy.  You can use it to turn debugging output on/off...

esp-01

1 [env:esp01]
2 platform = espressif8266
3 board = esp01
4 framework = arduino

esp-M3

1 [env:espM3]
2 platform = espressif8266
3 board = esp8285
4 framework = arduino

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...
