I thought this may be of interest
to some people. It's some code
that implements lightweight co-operative
threading support on the Pilot; feel
free to use it (or abuse it!) in any way
you want:
- Available on my web site
at www.golden.net/~deepnet
is CoordTask.zip. It contains source code,
a makefile, etc. that implements a lightweight
kernel to do manual threads in a safe way
on the Pilot.
- See 'CoordTask.h' for complete details, or
www.golden.net/~deepnet/CoordTask.html
- NO undocumented or 'wierd' Pilot
APIs are used. The implementation uses
stack copying and a bit of assembly code
to do the context switch.
- Why did I do this? The threading APIs on the Pilot
are undocumented, and developers are STRONGLY
discouraged from using them. Also, full
preemptive multitasking was overkill for what I
needed, and too 'heavy'. This solution is extremely
'lightweight' and 'safe' (although possibly not as
speedy as it could be).
If it useful for you, please let me know!
