[oopic] Re: trying to link a oKnob to a oPWM

Hello Denis,

Thanks for your fast replay.
Maybe it is better if i explain what i want to do a maybe you could
tell me what best to use, since you wrote that the oKnob is not very
stable in the extreme situations of its working range.
I need to control a PWM from a data logger with a 0-5 Volt analogue
output from the logger this should than give me the full range on the
PWM at a frequency of 19,6 kHz. Also i need a digital high when a
pulse is produced that is between 1 and 255 binary on the oPWM.

Thanks for your help in advance.

Regards,

Fred
