Hi Martin,
Thanks for the information. I was planning on using the board with my own
application board, so the information you provide was very useful.
It's a shame TS can't provide a simple programming environment as a VMWare
appliance which can be loaded into the free VMWare player... That would provide
the option for everyone to be able to use the same development system, and
would allow everyone to start programming more quickly.
I'll probably order a 7500 to play with, but I'm currently considering an XMOS
based board (XC-2) as it allows me to develop my I/O requirements more easily -
and there's no OS issues (as it doesn't use one!).
Regards,
PJE
