Setup

Using Linux (Ubuntu 18.04) + PlatformIO CLI (see my setup)

platformio.ini

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

lib_deps = olikraus/U8g2@^2.32.7

monitor_port = /dev/ttyUSB1
monitor_speed = 74880 ;Xtal on ESP8266 board (ESP-12E) is 26Mhz so 2880 * 26 = 74880

upload_speed = 921600 ; increased upload time from ~17 to ~3 secs.
build_type = debug

Running on ESP8266

Oh, hello there R2!
