UCD3138 Ramp generator question

Other Parts Discussed in Thread: UCD3138

Hello,

What is the effect of updating either the ramp value end register or the ramp step size register of the UCD3138 while it is running? Will the new values take affect "smoothly", or should the ramp be stopped & then re-started?

thanks,

Paul T.

Paul,

The Ramp Module was not designed or tested for register updates while the ramp is running. However, that being said the new values should take affect smoothly. Is this something you could try yourself?

Regards,

Hi Brandon,

I will try this out sometime, but probably not very soon. I'll post an update when I get some results.

thanks,
