Cortex-Mx and MSP430 Lite Targets

The Lite target is not fully compatible with the PowerForth target supplied with the other compiler editions. The Lite target has changes to reduce code size and for compilation to Flash. It may also change as we have to cope with an increasing range of chips.

Despite their small size, the Lite targets are capable of real applications. Duncan Louttit reports:

Attached is a photo of the robot that I used at the inaugural IET robot triathlon competition. I used the beta version of the MSP430 Lite compiler for the software. It had to compete in three events; line follower, drag race and time trial. It came 2nd in each competition and second overall. The Forth system is sufficient for this competition. I ended up with one download for the line follower and drag race and another one for the time trial. If I had had more time, we only had 8 weeks to do the whole thing including design and build the hardware, I could have done much better. The winner used a lot of commercial hardware and library routines for things like the PID controller.
