The factory provides a BUNCH of OOPic code at
http://www.micromegacorp.com/oopic.html
The simple example (that does nothing) is umfpu-serial.osc. It
provides the entire framework for an application without actually
doing anything. You insert your own code - perhaps something trivial
like add a couple of numbers and send the result to the serial port
as a string. There are many other LCD examples that will provide
guidance.
There is also a reference guide specific to the OOPic
http://www.micromegacorp.com/downloads/documentation/uMFPU-V3_1%
20OOPic.pdf The guide also provides tutorials.
Alas, I haven't bought the chip... I don't have an application for
it at this time.
