solution for SM fig. 4 point J
@tecstatic
thank you, now I can really handle KiCad thanks to your valuable tips
@all
there is an outstanding task for integration of frequency to voltage conversion as substitute for SM fig. 4. Point "J" seems to be a variable frequency source that has to be changed to linear voltage between 0V and Vbatt.
I have found LM 2907 http://www.national.com/ds/LM/LM2907.pdf and it seems to be a cheap and useful supplement for SM fig. 4. If it fits our needs it can be plugged and integrated into freedom circuit rev 0.6 via expansion port P7 (it can also be integrated to elder version rev 0.51). I´ll test it the next days.
stay tuned,

and I will not tell everyone it's time to get off of the boat once I get it up and running. People are looking for me to pull through for them, I just hope to make the world a better place for my childrens future. Only time will tell, right? Anyway it has been a long hard road and I am glad it almost over so I can get on with my life.
