You misunderstood my point, or maybe I was not clear enough. I know the smooth PWM algorithm are available for I3.2.
What I require is all the source code that's running on my handy board to be available. It's not the case for IC3.2, so I'm not using it. To be more precise I think the low-level routines should be available in source, I don't really care about the virtual machine.

| Hi everybody! I've been running both the Polaroid sonar sensor and Vector 2x digital compass on the HB without the expansion board. I'm using Kent Farnsworth's older sonar driver code that is designed for the motor driver output ports (U11). The (...) (25 years ago, 16-Apr-99, to lugnet.robotics.handyboard)
