This page serves as documentation for the Fiddle.
The Fiddle turns an ioNode into a generic gadget platform.
Footprint is compatible with the ioNode - it is made to be attached as a "backpack" module to an ioNode or a project using an ioNode.
The display is a 128x32 OLED using the very common SSD1306 driver.
These displays communicate via I2C.
A library is provided to control the display: ssd1306.
A tutorial is also available: Using an I2C OLED display
Input¶The Fiddle offers 7 inputs:
- 5-way tactile switch (mini-joystick)
- 2 buttons (not counting the reset button)
A library is provided to control the module: esp8266.
A tutorial is also available: Using an ESP8266 WiFi Module.
A MicroSD slot is included with the Fiddle. We provide a library for (micro-)SD cards: sdcard.
The Dooba SDK includes a library to facilitate development using the Fiddle: fiddle.
The wiki also includes a tutorial explaining how to use it: Using the Fiddle.
