This repo contains sample reactive programs that show data received from a Nintendo Wiimote using a Gtk GUI. All the programs are very simple; you are encouraged to open the haskell code and try to understand it. If the meaning is not obvious, you should open a bug report in keera-hails.

• In there are two kinds of Reactive Values:

  • Wiimote Accelerometer RVs, polled regularly.
  • GUI RVs, representing the texts in the entries.

• contains an additional pair of RVs for each field, and uses the Functional Reactive Programming DSL Yampa to integrate the values of the acceleration over time using Signal Functions.

• is a larger example featuring a glade gtk3 UI to show the state of a wiimote. All the buttons, plus accelerometer data, are supported.

In all cases, simple, declarative, reactive relations/rules are used to keep all Reactive Values in sync.

Compilation

Apart from installing all the dependencies, you should compile the program with the flags -threaded and -rtsopts, and run it with +RTS -V0.

Once the program is launched, press 1+2 (or sync near the battery slot) on your wiimote to connect to the computer.

You should expect to see the following (respectively, WMGui.hs and Minimal.hs):
