Is the proper way to use a common cathode alphanumeric display (datasheet) with Arduino to multiplex and switch the cathode pins on and off by changing between input and output? I can't find any reference.
I did go to DesignCon on Wednesday. 30% test equipment manufacturers (Anritsu, Agilent, etc). 30% connector manufacturers (Molex, Tyco, Amphenol, Hirose, FCI). Predominantly high speed connectors. 20% PCB fabs and PCBA shops 20% other stuff
@NickAlexeev Guess I missed the beer and goodies then.
@NickAlexeev I've been to an exhibition once where drinks, including beer, were free ... one stand had very happy personell. Left not a good impression with me.
@jippie At the last show I went to one of the German companies (Schott Glass? Huber+Suhner? Rohde&Schwartz? I don't remember at all) was serving pretzels and beer. I think they even had the server wear lederhosen.
I should have told them that as a Bavarian-American I was offended by their gross caricature of my culture...and they should serve me double beer to compensate.
@ThePhoton you are probably right, we didn't do much above 1GHz when I worked there. They did however have a piece of calibrated coaxial cable which was spec'd up to 10 GHz.
@ThePhoton Something tells me I shouldn't open it to check.
