Can you rewrite your PID algorithm to use only 16 bit integer
arithmetic? If not, are you willing to add an external floating point
coprocessor running on either the slow, bit-banged, I2C bus or the
slow, bit-banged, SPI bus? You may get some speed help from virtual
circuits but you need to consider that the OOPic may only execute 300
lines of code per second (plus or minus).

Given the availability of PID process controllers, using the OOPic
would be the hard way to do it. But it could probably be done.
