hi

&amp;quot;What is The maximum speed that I got Display the picture on
TFTLCD whit 1788 ?&amp;quot;&lt;/p&gt;

&lt;p&gt;
Since there are not a large number of people who want to play
video with the 1788 I think this is a task for you to find out.
Please come back with the width * height * frame-rate that you can
mange.&lt;/p&gt;

&lt;p&gt;
&amp;quot;I do not want the use to other processor all these things (read
the image from memory and displayed on the LCD) I want to do
1788&amp;quot;&lt;/p&gt;

&lt;p&gt;
An important thing - there is a big difference between &amp;quot;I want&amp;quot;
and &amp;quot;I can get&amp;quot;. With the 1788 you will have to keep down frame-rate
or resolution or both. And you will have to experiment to figure out
how much processor budget to use for memory card transfers +
decompression and how much to use for transfers to the LCD.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: How to use lpc 1788 display video?</title><link>https://community.arm.com/thread/131410?ContentTypeID=1</link><pubDate>Tue, 13 May 2014 00:37:42 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:ceaa0a63-ee56-418e-89dd-94b1379da0c7</guid><dc:creator>speed daemon</dc:creator><description>&lt;p&gt;&lt;p&gt;
If the time taken to show an image is too great then you need to
consider ALL aspects.&lt;/p&gt;

&lt;p&gt;
When it is taking four times longer to show a jpg than a bmp then
it is highly unlikely it&amp;#39;s just the lcd interfacing that you need to
consider. The processing required to decode a JPG is far greater than
that of a BMP.&lt;/p&gt;

&lt;p&gt;
It looks like you&amp;#39;re expecting too much from the processor.&lt;/p&gt;

hi&lt;br /&gt;
i previously study this documentation&lt;br /&gt;
but i use emwin and lcd 7&amp;quot;&lt;br /&gt;
But speed is displayed on the LCD is very low.&lt;br /&gt;
Almost every second a Photo(bmp)&lt;br /&gt;
And every 4 seconds a Photo(jpg)&lt;br /&gt;
But I need more speed&lt;br /&gt;
How can I do this faster (reading memory image and showing on the LCD
side) do&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: How to use lpc 1788 display video?</title><link>https://community.arm.com/thread/120325?ContentTypeID=1</link><pubDate>Mon, 12 May 2014 23:46:37 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:2ea1b2fb-2d39-4abd-8859-af7c4395506f</guid><dc:creator>Andy Neil</dc:creator><description>&lt;p&gt;&lt;p&gt;
Have you spent any time studying the &lt;b&gt;documentation&lt;/b&gt; for this
chip to determine its capabilities:&lt;/p&gt;

&lt;p&gt;

&lt;a href="http://www.nxp.com/products/microcontrollers/cortex_m3/LPC1788FET208.html#overview"&gt;www.nxp.com/.../LPC1788FET208.html&lt;/a&gt;&lt;/p&gt;

So, without any idea of whether it is appropriate or even capable
for this task, you&amp;#39;re just going to stubbornly insist upon it?&lt;/p&gt;

Video? Then you should consider a processor with video hardware -
i.e. something that can perform processing of video data and not just
have some ability to interface with a LCD panel.&lt;/p&gt;

&lt;p&gt;
Video means an ability to produce content and update lots of
pixels on that display for every single frame displayed - and also
that the frame rate is high enough. So hardware acceleration should
not be ignored.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
