====== GUI Options for Embedded Design ======

===== Arduino-based =====
Portability to [[http://espressif.com/ | ESP8266/ESP32]], [[https://www.pjrc.com/teensy/ | Teensy]], and similar devices is a huge plus.

==== Software ====
=== Drivers ===
== Character LCD ==

  * [[https://www.arduino.cc/en/Reference/LiquidCrystal | Arduino Liquid Crystal]]
  * [[https://github.com/gregington/BigCrystal | Arduino BigCrystal]]: big characters, serial and PFC8574 I2C input
  * [[https://github.com/gregington/BigCrystalTWI | Arduino BigCrystalTWI]]: big characters, MCP2008 I2C input

== Monochrome graphics ==
  * [[https://github.com/olikraus/u8g2/wiki | u8g2 ]]: monochrome graphics library
  * [[https://github.com/olikraus/u8glib/wiki | u8glib ]]: monochrome graphics library
  * [[https://bitbucket.org/bperrybap/openglcd/wiki/Home | openGLCD]]: GPL, appears to be monochrome only
  * [[http://www.rinkydinkelectronics.com/library.php?id=49 | MGLCD]]: character LCDs

==== Hardware ====
=== Display only ===
  * Cheap 16x2 and similar character LCD
  * Cheap graphic LCD
  * TFT graphic LCD
  * OLED
  * ePaper

=== Display with input ===
  * TFT capacitive touch
    * eg [[https://www.adafruit.com/product/1947]]
  * [[https://nextion.itead.cc/ | Nextion]] via iTead

==== Sources ====
  * [[http://www.buydisplay.com/ | East Rising]]:  Character LCD, graphic LCD, TFT (w and w/o touch), OLED, e-Paper.
  * [[https://www.waveshare.com/product/modules/oleds-lcds.htm | Waveshare]]: Particularly known for e-Paper, but also character LCD, graphic LCD, TFT (w and w/o touch), OLED.
  * [[https://www.adafruit.com | Adafruit]] : Comes at a premium, e.g. [[https://www.adafruit.com/product/1047 | 8x8 matrix]].

===== RPi/BeagleBone-based =====

==== Software ====

=== Kivy ===

=== HTML ===
  * See [[hybrid_apps:alternative_architecture_for_hybrid_applications|An Alternative Architecture for Hybrid Applications]] and [[hybrid_apps:alternative_architecture_notes|Notes for Alternative Architectures for Hybrid Applications]].
  * [[https://electronjs.org/|Electronjs]] and similar.

=== Qt ===
  * Currently deprecated for my use due to licensing hassles.

==== Hardware ====
  * For BeagleBone, 4.3" and 7" touchscreen capes are available.
  * For RPi, 7" is the canonical, 2.8" also appears to be available.
