 Hi i am doing my first project to understand about ARM
stm32f407 microprocessor using TTL/CMOS logic gates externally,and
check the function of a SOP design by generating 
inputs to the logic and reading the outputs. So LEDs will be used as
indicators</description><dc:language>en-US</dc:language><generator>Telligent Community 10</generator><item><title>RE: First project on ARM</title><link>https://community.arm.com/thread/62533?ContentTypeID=1</link><pubDate>Wed, 29 Jan 2014 18:44:10 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:7af9b82f-8fd4-423f-9a4e-4ca0a2e22fe1</guid><dc:creator>Westonsupermare Pier</dc:creator><description>&lt;p&gt;&lt;p&gt;
So go get a manual for the chip and board you&amp;#39;re using. Study
them.&lt;/p&gt;

&lt;p&gt;
Download the firmware library from ST&lt;/p&gt;

&lt;p&gt;
Review the code examples, with some focus on configuring GPIO
pins.&lt;/p&gt;

&lt;p&gt;
Build some of the examples. Study the results.&lt;/p&gt;

&lt;p&gt;
Check the board documentation to understand which pins are free to
use, and which pins are tolerant of 5V inputs, if that&amp;#39;s what your
circuits generate.&lt;/p&gt;

&lt;p&gt;
You have 4 outputs, cycle through the 16 binary output
combinations, and after setting the outputs, examine the two inputs.
You could compare these values to known correct values, or store them
in a table for display or comparison later.&lt;/p&gt;

&lt;p&gt;
If you don&amp;#39;t understand how to do aspects of the project, break
them down to simpler tasks. There is plenty of documentation if
you&amp;#39;re interested in learning how to do things.&lt;/p&gt;

&lt;p&gt;
SOP, sum of products?&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
