Graphics Primitives by Phillip Burgess
Each device-specific display library will have its own constructors and initialization functions. These are documented in the individual tutorials for each display type, or oftentimes are evident in the specific library header file. The remainder of this tutorial covers the common graphics functions that work the same regardless of the display type.

The function descriptions below are merely prototypes — there’s an assumption that a display object is declared and initialized as needed by the device-specific library. Look at the example code with each library to see it in actual use. For example, where we show print(1234.56), your actual code would place the object name before this, e.g. it might read screen.print(1234.56) (if you have declared your display object with the name screen).

ESP8266 WiFi Weather Station with Color TFT Display We were playing around already with LED MATRIX's, devices to visualize measured values and/or texts. In this blog post (Tutorial) we will use a TFT Display (Thin-film-transistor liquid-crystal display) with touch screen to display a three (3) days weather forecast with moon phases. This…

Adafruit LED backpacks make it incredibly simple to add small bitmapped displays to a project. Each requires just four wires: power, ground and two communication lines to a microcontroller.

Two common questions we receive:

How can I use more than one 8x8 matrix backpack in an Arduino sketch?

Can I have two (or more) matrices always showing the same image?

This tutorial demonstrates both.

We’ve had spooky Halloween displays on the brain lately, but the concepts here are equally applicable to more innocent schemes!

This is a quick tutorial for our 128x64 and 128x32 pixel monochrome OLED displays. These displays are small, only about 1" diagonal, but very readable due to the high contrast of an OLED display. Each OLED display is made of 128x64 or 128x32 individual white OLEDs, each one is turned on or off by the controller chip. Because the display makes its own light, no backlight is required. This reduces the power required to run the OLED and is why the display has such high contrast; we really like this miniature display for its crispness!

In this project we’ll show you how to make a WiFi enabled, portable Weather Station using an ESP8266. LINKS BELOW! The software, written by Daniel Eichhorn, uses the Wunderground API to pull weather data. It shows the date, time, current weather conditions, 4-day forecast and even moon phases.

The user interface features lovely typography and icons that makes really a clean layout. The 2.4” TFT Feather Wing combined with the Adafruit Feather HUZZAH ESP8266 make assembling this project incredibly easy. Full Tutorial, Files and Code: https://learn.adafruit.com/wifi-weath...
