Subject: [alt-beam] Re: PNC problems.
Hi Jakub
Sorry somebody treated you that way, I understand you know electronics!
Actually Chiu gave the answer but you probably didn't realize it.
Your PNC problem is simple : you connected Vcc and Gnd to the RC in
reverse! So instead of holding the output high for a few seconds and
then low after, it operates in reverse. By adding an extra inverter
at the output you corrected the problem but with extra parts.
Anyway I hope this helps. Have fun and keep on learning more about these
funny little Beam circuits (ie BiCore) which are sometimes hard to
understand even for electronics experts.
best regards

Few days ago I wrote an e-mail about my PNC problems. I got only one
leter but nothing constructive. The author of the leter treated me like
complete ignorant who doesent know anything about electronics. And this
is suppose to be an educational mailing list! ANYONE who can
help me please reply. I managed to go around the problem and designed my
own PNC solution but I stel whant to know what was wrong with
the previous circuit. Heres a copy of my previous e-mail:
