Tutorial - Beginning Embedded Electronics - 9
about 5 years ago
I really like your tutorial and now have a schematic with 9 ICs (8 are optos). Through hole – old school 5V ttl. Two questions:
(1) I pulled a 74165 from the eagle library. How do I tell the board tool about its power pins? The block diagram has data and control lines only. Any helpful URLs?
(2) I auto-routed the board, then I added some resistors. The “error checker” states the resistors are not part of the board. Duh. Can I transfer them over without re-laying out the whole board (it takes about 30 minutes, really, no biggie).
thanks // brian
