A simple yet powerful library for controlling graphical displays. Multiple display controllers are supported using inheritance.
Dependents: mbed_rifletool Hexi_Bubble_Game Hexi_Catch-the-dot_Game Hexi_Acceleromagnetic_Synth
NOTE: This library is in beta right now. As far as I know, everything here works, but there are many features that are lacking so far. Most notably containers, button handling, and display drivers other than the SSD1306.
