Do you already know &amp;quot;normal&amp;quot; C?&lt;/p&gt;

&lt;p&gt;
If not, learning the &lt;b&gt;&amp;#39;C&amp;#39; programming language&lt;/b&gt; must be your
first step:&lt;/p&gt;

&lt;p&gt;
&lt;a href="http://bit.ly/X5Atml"&gt;http://bit.ly/X5Atml&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;
You will also need to understand the &lt;b&gt;8051 architecture&lt;/b&gt;. It
is an extremely long-established and widely-used architecture - there
is no shortage of resources; eg:&lt;/p&gt;

&lt;p&gt;
&lt;a href="http://www.8052.com/faqs/120112"&gt;www.8052.com/.../120112&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;
&lt;a href="http://www.8052.com/forum/tutorial"&gt;www.8052.com/.../tutorial&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;
&lt;a href="http://www.keil.com/books/8051books.asp"&gt;http://www.keil.com/books/8051books.asp&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;
In addition to the general 8051 architecture, you will need to
understand the specific details of the particular chip(s) you are
using - for this, you will have to study the &lt;b&gt;Manufacturer&amp;#39;s
&lt;i&gt;Datasheets&lt;/i&gt;&lt;/b&gt;.&lt;br /&gt;
You should also take time to browse the &lt;b&gt;Manufacturer&amp;#39;s website&lt;/b&gt;
for supporting materials - application notes, examples, tutorials,
etc.&lt;/p&gt;

&lt;p&gt;
You will also need to study the &lt;b&gt;Keil &lt;i&gt;manuals&lt;/i&gt;&lt;/b&gt; for the
implementation-specific details particular to the C51 tools:&lt;/p&gt;

&lt;p&gt;
&lt;a href="http://www.keil.com/support/man_c51.htm"&gt;http://www.keil.com/support/man_c51.htm&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;
You should also take time to browse the &lt;b&gt;Keil website&lt;/b&gt; for
supporting materials - application notes, examples, tutorials,
etc.&lt;/p&gt;

&lt;p&gt;
And, of course, don&amp;#39;t forget the resources at &lt;b&gt;your school&lt;/b&gt; -
teachers, lesson notes, library, etc.&lt;/p&gt;

&lt;p&gt;
Not to mention &lt;b&gt;google...&lt;/b&gt;&lt;/p&gt;

Was it your teacher who sent you here?&lt;/p&gt;

&lt;p&gt;
To get extra help because the school is too bad to manage to give
the proper background knowledge?&lt;/p&gt;

&lt;p&gt;
Can&amp;#39;t you post the name of the school, so other people can avoid
it?&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
