I am using the Accutron prototyping board with the ADuC841
controller to develop an application that converts voltages to power
to display power, VSWR and temperature and displays the results on a
4 line LCD display.

Doh!! And guess what, I was right. Tied the R/W line to ground and
everything behaves perfectly again. Hey-ho, the things we dream up to
waste our time.&lt;/p&gt;

Sorry, I forgot to add that the reset is via a button on the board
and is tied to a suitable level - no not RC, I don&amp;#39;t do that.&lt;/p&gt;

The development board is nothing special, just an 841 with a
serial interface for downloading. Debugging is by software! I put in
leds or messages on the lcd to see what is happening!&lt;/p&gt;

&lt;p&gt;
Actually, while reclining in my bath this evening I had a thought
- I once tried to utilise the BUSY flag of the lcd display for
getting the write timing correct. That did not work so I reverted to
using delays (horrible I know). It occurred to me that I have left
the R/!W pin connected to a port rather than connected to supply
ground. This could well account for the erratic behaviour and will be
investigated tomorrow. I will let you know the outcome.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Strange reset behaviour</title><link>https://community.arm.com/thread/59862?ContentTypeID=1</link><pubDate>Thu, 22 Sep 2011 08:59:58 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:888f6470-620e-4be2-b429-cd977db60a7b</guid><dc:creator>&amp;#178;erik malund</dc:creator><description>&lt;p&gt;&lt;p&gt;
1) what kind of reset - hopefully not RC&lt;br /&gt;
2) could very well be (an) uninitialized variable(s)&lt;br /&gt;
what debugging tools do you have? JTAG/ICE etc&lt;/p&gt;

&lt;p&gt;
&lt;i&gt;I am using the Accutron prototyping board&lt;/i&gt;&lt;br /&gt;
which I&amp;#39;m sure some will know what is, I do not&lt;/p&gt;
