Hi Guys, 

 
What is meant by &amp;quot;reserve PAYLOW_BUFFER_SIZE (0x08G4 is defined as
default value) bytes as a reception buffer&amp;quot; , PAYLOW Length , Paylow
data. How to write the C code for this. 

 
Can anyone please help me on this.

Note that the question was vague in the extreme, and lacking a
great number of important details.&lt;/p&gt;

&lt;p&gt;
Therefore the answer was based on a great deal of assumptions and
guesswork - so there is a high risk that it is not (quite) right for
your particular situation...&lt;/p&gt;

I don&amp;#39;t think we should assume to much until the OP do return and
actually gives us a bit of explicit information to work on.&lt;/p&gt;

PAYLOAD == PAYLOW&lt;/p&gt;

&lt;p&gt;
thats my assumption.&lt;/p&gt;

&lt;p&gt;
can sam confirm?&lt;/p&gt;

&amp;quot;PAYLOW that&amp;#39;s the data we actually interested in&amp;quot;&lt;/p&gt;

&lt;p&gt;
Are you sure you are not thinking about payload?&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: req: i want answer for my  qestion</title><link>https://community.arm.com/thread/77899?ContentTypeID=1</link><pubDate>Wed, 04 Nov 2009 00:54:11 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:5282088a-a655-42cc-a0b1-0dea44217d1f</guid><dc:creator>JEREMY SWAN</dc:creator><description>&lt;p&gt;&lt;p&gt;
Hello sam,&lt;/p&gt;

&lt;p&gt;
It seems you&amp;#39;re writing some communication code.&lt;/p&gt;

&lt;p&gt;
PAYLOW_BUFFER_SIZE - Total amount of ram reserved as Receive
Buffer&lt;br /&gt;
PAYLOW Length - It&amp;#39;s total size of &amp;#39;actual data&amp;#39; within 1 frame.&lt;br /&gt;
PAYLOW Data - It&amp;#39;s the actual data of interest within 1 frame.&lt;/p&gt;

&lt;p&gt;
If you&amp;#39;ve written code for communications (typically asynchronous
i.e. only data is transmitted &amp;amp; receiver generates it&amp;#39;s own clock
as per baud) you know that -&lt;br /&gt;
1) Receiver can get data at any time.&lt;br /&gt;
2) Received data may be out-of-order, corrupted, incomplete.&lt;br /&gt;
3) Data may be too large to transmit in one go.&lt;br /&gt;
4) Receiver may not be able to cope with all the incoming data at the
rate of transmission.&lt;br /&gt;
5) There may be more than one receiver, more than one
transmitter.&lt;br /&gt;
etc.. etc..&lt;/p&gt;

&lt;p&gt;
So you&amp;#39;ve what are known as &amp;#39;Communication Protocols&amp;#39;. They define
the rules which are adhered to by transmitter as well as receiver to
successfully communicate with each other.&lt;/p&gt;

&lt;p&gt;
Typically these communcation protocols define, How data is
transmitted as FRAMES. That&amp;#39;s chunk of data+additional data. This
additional data may include receiver address, frame no., crc,
time-stamp, transmitter id, data id etc. This helps receiver(s) to
correctly identify data addressed only for them, decode it, ask
resend if it was corrupted.&lt;/p&gt;

&lt;p&gt;
Receiver seperates data within frame as 1) PAYLOW that&amp;#39;s the data
we actually interested in &amp;amp; 2) Additional data. You can see any
introductory book on TCP/IP or other comm. protocols, you&amp;#39;ll get this
in much more details.&lt;/p&gt;

&lt;p&gt;
As for defining them in C it is just as array - either of simple
bytes or of some struct defined. This depends on protocol you&amp;#39;re
implementing.&lt;/p&gt;

&lt;p&gt;
I may add that please be more elaborative with your questions so
that you may get more detailed answers.&lt;/p&gt;

&lt;p&gt;
Hope that helps,&lt;/p&gt;

&lt;p&gt;
JEREMY SWAN&lt;/p&gt;

I figure the same Google link that describes the
PAYLOW_BUFFER_SIZE constant also describes the number base.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: req: i want answer for my  qestion</title><link>https://community.arm.com/thread/57197?ContentTypeID=1</link><pubDate>Wed, 04 Nov 2009 00:01:50 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:700c06c8-9c91-431f-800b-8b80cee22087</guid><dc:creator>Andy Neil</dc:creator><description>&lt;p&gt;&lt;p&gt;
What number base is that??&lt;/p&gt;

What does it mean when someone asks about a variable or constant
name, but forgets to mention where he/she found the name in the first
place? That they do not know what processor they are using or where
they found the source code?&lt;/p&gt;
