  • I think i already know the answer to this, but...

    Let's say I have a matrix keyboard, where connecting line X0 with line Y0 results in a keypress. Pretty standard part.

    I connect all the rows/columns, one each to a pin on this or similar multiplexing chip. Is there any way, with one chip, to connect those pins to each other?

    I figure I can do it with two mux ICs, one for columns, one for rows, joined at their common I/O pin, but I'm trying to save room and parts by trying to combine that into one chip. If not this one, then maybe someone can recommend one? I need an 8x10 matrix.

  • would the spacing on these connectors fit the FSRs sparkfun carries (e.g. http://www.sparkfun.com/products/9673 )

No public wish lists :(
