The dspmc only seams to work properly if...

Hi,
Thanks again for your time
don't want to start any dispute, but are you guys saying the same thing or do you have different opinions?

but im still confused.
dam didn't realise my attachment got compressed
the best i can do then is provide a link to my other...

hello everyone,

first post so go easy:)
Trying to work out the right way to earth dyn4 servo system with a dspmc controller

still confused if i need to bond the dc common buss to earth ground...
