====== 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.

===== 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.
