I tried to use a cap from 22 pF, 33 pF and a trimmer, nothing did
make influence, except the appearance of my hand by the pins osci and
osco did make a significant difference. The datasheet indeed says
that the cap is used for adjustment, and is not necessary.
How come the pcf8583 works without a crystal as well?
many thanks for anybody who can help me out here!
