I&amp;#39;ve got a big problem with the LCD showing fixed text that never
changes.&lt;/p&gt;

&lt;p&gt;
I&amp;#39;ve tried changing the program but it doesn&amp;#39;t help.&lt;/p&gt;

&lt;p&gt;
Where can I send the code?&lt;/p&gt;

There are many HCT chips that may be used. Hence, many ways to
connect them too.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Help with LCD</title><link>https://community.arm.com/thread/147342?ContentTypeID=1</link><pubDate>Wed, 27 Jun 2007 00:09:44 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:eb623a54-3c06-44d9-8ab6-91d058f8bdc3</guid><dc:creator>Ales Moskon</dc:creator><description>&lt;p&gt;&lt;p&gt;
Can you write me witch number is this HCT please,&lt;br /&gt;
and how to connect. LCD is 5V and also working with&lt;br /&gt;
3V.&lt;/p&gt;

Maybe the loops in delay_ms() are optimised out?&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Help with LCD</title><link>https://community.arm.com/thread/146088?ContentTypeID=1</link><pubDate>Tue, 26 Jun 2007 07:21:30 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:42f8b674-999e-40db-8620-3cbff1fa9e11</guid><dc:creator>erik  malund</dc:creator><description>&lt;p&gt;&lt;p&gt;
&lt;i&gt;I have LPC936 and CM2040 (4x20 LCD).&lt;/i&gt;&lt;br /&gt;
Insert a 5V powered HC&lt;b&gt;T&lt;/b&gt; between the 3V3 LPC and the 5V LCD.
The slow risetimes from the &amp;#39;wonderful&amp;#39; 5V compatible pins can &amp;#39;kill&amp;#39;
the LCD.&lt;/p&gt;

Probably this is importaint:&lt;br /&gt;
I have LPC936 and CM2040 (4x20 LCD).&lt;br /&gt;
I connect&lt;br /&gt;
RS---P2.2&lt;br /&gt;
EN---P2.1&lt;br /&gt;
RW---P2.0&lt;/p&gt;

While you&amp;#39;re there, look at the &amp;#39;Tutorials&amp;#39; section...&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Help with LCD</title><link>https://community.arm.com/thread/135038?ContentTypeID=1</link><pubDate>Thu, 21 Jun 2007 02:37:37 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:3248a3f6-a7c0-47ab-bbaf-71e33f8d3f64</guid><dc:creator>ImPer Westermark</dc:creator><description>&lt;p&gt;&lt;p&gt;
Yes, I was thinking about something else when writing the
text.&lt;/p&gt;

&lt;p&gt;
I definitely meant a thread per week.&lt;/p&gt;

&lt;p&gt;
Sorry for the confusion!&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Help with LCD</title><link>https://community.arm.com/thread/123898?ContentTypeID=1</link><pubDate>Thu, 21 Jun 2007 02:05:28 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:484252eb-3356-4157-9774-707cab9347f2</guid><dc:creator>Andy Neil</dc:creator><description>&lt;p&gt;&lt;p&gt;
&lt;i&gt;&amp;quot;There is probably a thread/weak&lt;/i&gt; (sic) &lt;i&gt;about the use of
displays.&amp;quot;&lt;/i&gt;&lt;/p&gt;

&lt;p&gt;
I think he means, &lt;i&gt;&amp;quot;There is probably a thread &lt;b&gt;per week&lt;/b&gt;
about the use of displays.&amp;quot;&lt;/i&gt;&lt;/p&gt;

&lt;p&gt;
In other words, it&amp;#39;s already been thoroughly discussed and you
just need to do a little &amp;#39;&lt;b&gt;Search&lt;/b&gt;&amp;#39; to find what you&amp;#39;re looking
for...&lt;/p&gt;

&lt;p&gt;
Did the Application Note suggested earlier not help you?&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Help with LCD</title><link>https://community.arm.com/thread/112974?ContentTypeID=1</link><pubDate>Thu, 21 Jun 2007 00:38:37 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:3d713878-925e-4a39-acb1-8a77b5696f54</guid><dc:creator>Ales Moskon</dc:creator><description>&lt;p&gt;&lt;p&gt;
Can you explain this sentence:&lt;br /&gt;
There is probably a thread/weak about the use of displays.&lt;/p&gt;

&lt;p&gt;
Im sorry im bad in other language.&lt;/p&gt;

How much have you searched on this forum? There is probably a
thread/weak about the use of displays.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Help with LCD</title><link>https://community.arm.com/thread/75208?ContentTypeID=1</link><pubDate>Wed, 20 Jun 2007 07:19:48 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:7985afa7-6f4e-4b18-bd4e-32866f5a55dd</guid><dc:creator>Ales Moskon</dc:creator><description>&lt;p&gt;&lt;p&gt;
