Is it really worth it, trying to waste other peoples time just for
the fun of it? Go abuse another forum instead!&lt;/p&gt;

i have an 80sa451 but it is running slow and i want to overclock
to run quigly.&lt;/p&gt;

&lt;p&gt;
i know you need more wattage to do it.&lt;/p&gt;

&lt;p&gt;
but is it possible to increase the wattage source.&lt;br /&gt;
i.e for example if a consider a battery with 12v,6A, then the watts
it can be produce is maximum of 72w. is it possible to extract more
than that i.e 200w .by connecting any circuits.&lt;/p&gt;

&lt;i&gt;&amp;quot;use the &amp;#39;union&amp;#39; command in ANSI-C&amp;quot;&lt;/i&gt;&lt;/p&gt;

&lt;p&gt;
Why? What would that achieve?&lt;/p&gt;

&lt;p&gt;
&lt;i&gt;&amp;quot;Then You can control a X-dimensional array&amp;quot;&lt;/i&gt;&lt;/p&gt;

&lt;p&gt;
&amp;#39;C&amp;#39; naturally supports multi-dimensional arrays - unions have
nothing to do with it!&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: About printf</title><link>https://community.arm.com/thread/135201?ContentTypeID=1</link><pubDate>Mon, 12 Nov 2007 14:40:27 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:145e36ad-90ff-4f56-b04a-475005bb577b</guid><dc:creator>ImPer Westermark</dc:creator><description>&lt;p&gt;&lt;p&gt;
I know how to build a 16-led &amp;quot;4-dimensional&amp;quot; hypercube (i.e.
2x2x2x2 LED) folded into two 3-dimensional cubes inside each other,
but I don&amp;#39;t want to even think about a 4x4x4x4 hypercube with 256
LED. The folding part is slightly outside my geometric thinking
capabilities, and if the fourth dimension isn&amp;#39;t folded into our three
dimensions but temporal, I would have problems sending the control
signal forward or backward in time.&lt;/p&gt;

&lt;p&gt;
My next problem is that a 4x4 side is too little for projecting
text, so I can&amp;#39;t use it as output device for the printf()
function.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: About printf</title><link>https://community.arm.com/thread/124235?ContentTypeID=1</link><pubDate>Mon, 12 Nov 2007 13:19:01 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:7f3e269b-03d2-4c36-b3b2-e8754f263853</guid><dc:creator>Andy Neil</dc:creator><description>&lt;p&gt;&lt;p&gt;
Does this have anything even remotely to do with printf?&lt;/p&gt;

&lt;p&gt;
&lt;i&gt;&amp;quot;I want to build a 4x4x4x4 LED cube using blue LEDs&amp;quot;&lt;/i&gt;&lt;/p&gt;

&lt;p&gt;
Using them for what?&lt;/p&gt;

&lt;p&gt;
&lt;i&gt;&amp;quot;i want it working.&amp;quot;&lt;/i&gt;&lt;/p&gt;

&lt;p&gt;
Again, what does &amp;quot;working&amp;quot; mean?&lt;br /&gt;
Doing what??&lt;/p&gt;

&lt;p&gt;
&lt;i&gt;&amp;quot;you can see some sample videos on youtube&amp;quot;&lt;/i&gt;&lt;/p&gt;

&lt;p&gt;
The whole youtube site is entirely full of videos of all sorts of
stuff - what one(s) are you talking about??&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: About printf</title><link>https://community.arm.com/thread/130223?ContentTypeID=1</link><pubDate>Mon, 12 Nov 2007 13:17:42 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:9942e7cc-ff41-4550-970b-ec486757f196</guid><dc:creator>afta haight</dc:creator><description>&lt;p&gt;&lt;p&gt;
An idea would be to use the &amp;quot;union&amp;quot; command in ANSI-C. Then You
can control a X-dimensional array. You can possibly use a random
function or some other function on how to lit the differen t
LED:s.You also have to check the different compiler manuals wether
they support onions or not.&lt;/p&gt;

&lt;p&gt;
If you need help we listen and you ask&lt;/p&gt;

&lt;p&gt;
Good luck!&lt;/p&gt;

I&amp;#39;m afraid my species is limited to manipulating a mere three
spatial dimensions, so I could at best help you with a 3x3x3
cube.&lt;/p&gt;

&lt;p&gt;

Hi,&lt;/p&gt;

&lt;p&gt;
I want to build a 4x4x4x4 LED cube using blue LED&amp;#39;s or bicolor
(RGB LED&amp;#39;s). Has anyone built something like this? Any schematics,
code? No matter what microcontroller used. Buy i want it working.&lt;/p&gt;

&lt;p&gt;
you can see some sample videos on youtube.&lt;/p&gt;

&lt;p&gt;
thank&amp;#39;s for any help&lt;/p&gt;

The question has come up several times - so try a bit of searching
(don&amp;#39;t forget the &amp;#39;Advanced&amp;#39; search)...&lt;/p&gt;

There must be some problem with caching or delayed insert on the
server. After my first try, a full reload of the page did not contain
any answer.&lt;/p&gt;

Either write your own com2_printf() that makes use of vsnprintf()
and then copies the formatted string to the second port, or add a
variable that controls which physical port that should receive the
output from printf().&lt;/p&gt;

&lt;p&gt;
By the way, I don&amp;#39;t like forums that tells me that I have already
posted once, when the forum has specifically not accepted the
post...&lt;/p&gt;
