Hi, I'm trying to implement an I2C controller for my project, and have started from the Xilinx application note XAPP333.
ftp://ftp.xilinx.com/pub/applications/refdes/xapp333.zip (Need to register to download I think). The I2C controller section is an VHDL entity, and the SDA / SCL lines are defined as: -- I2C bus signals sda : inout std_logic; scl : inout std_logic; So.. my total NOOB question.. when I make a symbol for that, and instantiate it in my schematic, exactly how to I hook up those signals to a bi-directional IO buffer. The IOBUF has explicit I, O and T (direction) connections. -- Peter Clifton Electrical Engineering Division, Engineering Department, University of Cambridge, 9, JJ Thomson Avenue, Cambridge CB3 0FA Tel: +44 (0)7729 980173 - (No signal in the lab!) _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
