After having selected the target-platform you are going to use, this is where you go to specify the interfaces you wish to use. Each pin can be clicked, after which it shows a drop-down list with the functions/protocols it can support. The available functions depend on the pheripherals provided by the microcontroller/hardware-platform and the built-in libraries provided by the XPad-target.</FONT></div> <bR> <div> <B>E</B><FONT SIZE="2" COLOR="#003300" FACE="Arial" >xamples are:</FONT></div> <div> <IMG BORDER="0" SRC="Symb075c00b700c8ff000000.gif" HEIGHT="13" WIDTH="24" ALIGN="bottom" HSPACE="0" VSPACE="0">I2C SDA and CLK lines</div> <div> <IMG BORDER="0" SRC="Symb075c00b700c8ff000000.gif" HEIGHT="13" WIDTH="24" ALIGN="bottom" HSPACE="0" VSPACE="0">RS232 TX and RX lines</div> <div> <IMG BORDER="0" SRC="Symb075c00b700c8ff000000.gif" HEIGHT="13" WIDTH="24" ALIGN="bottom" HSPACE="0" VSPACE="0">1Wire (Dallas) dataline</div> <div> <IMG BORDER="0" SRC="Symb075c00b700c8ff000000.gif" HEIGHT="13" WIDTH="24" ALIGN="bottom" HSPACE="0" VSPACE="0">Output Pulses</div> <div> <IMG BORDER="0" SRC="Symb075c00b700c8ff000000.gif" HEIGHT="13" WIDTH="24" ALIGN="bottom" HSPACE="0" VSPACE="0">LCD datalines (HD44780 based)</div> <div> <IMG BORDER="0" SRC="Symb075c00b700c8ff000000.gif" HEIGHT="13" WIDTH="24" ALIGN="bottom" HSPACE="0" VSPACE="0">Analog input</div> <div> <IMG BORDER="0" SRC="Symb075c00b700c8ff000000.gif" HEIGHT="13" WIDTH="24" ALIGN="bottom" HSPACE="0" VSPACE="0">Discrete input</div> <div> <IMG BORDER="0" SRC="Symb075c00b700c8ff000000.gif" HEIGHT="13" WIDTH="24" ALIGN="bottom" HSPACE="0" VSPACE="0">Discrete output</div> <bR> <div> <FONT SIZE="2" COLOR="#FF0000" FACE="Arial" ><B>B</B></FONT>y means of a <FONT SIZE="2" COLOR="#0000FF" FACE="Arial" >"Bus Id"</FONT> pins can be combined into a single multi-pin protocol. (I.e. the I2C SDA and CLK pins have the same Bus Id number). These Bus Id show up in your model as Bus-variables, which you can simply pass to the built-in libraries to generate the correct signals, without you having to border about the pins ever again. If you change your mind about the pin-assignment, all you have to do is to re-assign the pins and use the same Bus Id for the new combination. Your model will automatically use the new setting during simulation and compilation!</div> <bR> <div> <B>F</B><FONT SIZE="2" COLOR="#003300" FACE="Arial" >urthermore you can specify some global platform-dependent information here, such as:</FONT></div> <div> <IMG BORDER="0" SRC="Symb075c00b700c8ff000000.gif" HEIGHT="13" WIDTH="24" ALIGN="bottom" HSPACE="0" VSPACE="0">crystal frequency (the built-in libraries will automatically adjust their timing accordingly);</div> <div> <IMG BORDER="0" SRC="Symb075c00b700c8ff000000.gif" HEIGHT="13" WIDTH="24" ALIGN="bottom" HSPACE="0" VSPACE="0">memory map information (location of RAM, ROM, Stack, etc) .</div> <bR> <div> <B>A</B><FONT SIZE="2" COLOR="#003300" FACE="Arial" >fter submitting your specification XPad evaluates the validity of your configuration and returns feedback if a problem was detected.</FONT></div> <bR> <div> <FONT SIZE="2" COLOR="#FF0000" FACE="Arial" ><B>A</B></FONT>lternatively each target comes with a <FONT SIZE="2" COLOR="#0000FF" FACE="Arial" ><I>wizard</I></FONT>, which can do the configuration for you.
