One of our favorite designers Marcus, creator of the Hybrid SID player, made a PIC32 development board that works with the snap-together Grove rapid development system. An operating system called StickOS runs simple BASIC programs.
His work is now on sale at Seeed Studio.
Via the forum.
Does the Basic have a math package?
@Chuckt – You can checkout StickOS and the various features it has at http://www.cpustick.com/ or http://www.cpustick.com/features.htm
Rich (the designer) is a nice guy and helpful.
