FunKey Freedom Has Multiple Modes. Here's how to set them:
There are four modes and it's easy to change from one to the other.
--Remove all connections, disconnect the USB
--Connect the designated holes for any mode (W/H, for example) on the board with an alligator clip
--Power the board with the USB cable
--Remove the alligator clip
--FunKey Super is now in the desired mode, and will stay there until reconfigured to a different mode
--Onboard LEDs show the mode
Input/Output Mode: D/K maps inputs to outputs, plus specific built-in helper code to support a servo motor. You can use computer power via USB cable or from a battery box with no computer connection necessary. See I/O page for details.
Arduino Mode. FunKey Super is based on a standard Arduino chip. So you can code it directly with the Arduino IDE. In this mode, FunKey Super offers great convenience in providing multiple analog and digital port access, with a full power and ground connection for each port, so it's much more simple to use than the many Arduino boards and clones on the market. However, if you go to Arduino mode by installing and using the Arduino IDE, it will erase the built in modes.
