I built an Arduino-compatible pressure multi-touch controller called Snowboard and tried to use CCV to add multi-touch support to it.
Since 2D force image is sent to a PC via serial port, I modified codes of CCV1.5 so that it can get raw touch image data from a serial port.
And here is a result video. CCV is now working very well with my Snowboard.
