So just AND the 0-255 value with 31.

I don't know if you would consider it simple, but the HAL_RAND.ASPIC module
contains a pseudo-random number generator.  It is available in the HAL PIC
project from http://www.embedinc.com/pic.  Remeber that Embed Inc software
releases must be installed in oldest to newest order.  I don't think this
release has been updated in a long time.  If you install it, you must go
back and re-install any newer releases you wish to function correctly.
