Re: EHP External Hardware Proposal

Bertho,
Glad you pointed that out.

I'm not doing servo systems.. and I don't want DSP at the moment... My latest investment is going into USB development equipment for
a new project later this year...

I'll just do it my way, and then if anyone with existing hardware want it, they can use it...

regards
Hans W
