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). IŽll test it the next days.
stay tuned,
