RS-485 Unterminated Bus and bias resistors After looking at several application notes (by National, TI, B&B Electronic...) I can't understand if I can bias the two-wire bus without inserting a 120 ohm resistor between A and B cables. Reading B&B Electronics (http://www.dzjsw.com/shu/bz22.pdf) it seems to be possible (pages 18 and 19). Reading National (htt... 9 Mar 2010 14:36

Embedded C++ Book? Any book recommendations for C++ techniques for deeply embedded systems? I know how to do this, but I kind of picked it up by osmosis in the 90's. I need a book I can recommend to folks. I'm not looking for something that assumes a hard disk and a Pentium or Power PC -- I'm looking for a solid reference for... 10 Mar 2010 14:10
