| Shadow in the S6A0069 16x2 LCD |
 Posted: Thu Jul 11, 2013 6:10 pm |

Hi Everyone!
I could not fix the "shadow" that appears when any variable value changes in the blue LCD (S6A0069). Sliding texts is even worse.
In the image below you can see the back shadow in purple when changing from 850Rpm to 900Rpm.
It might be related to currently LCD update rate that I'm using (100ms), but the strange part is that I had no issue with the hd44780 controller by usuing the same update rate! Video (Sorry only in portuguese) available at http://www.youtube.com/watch?v=mJWwJaoi9q0
I've already tried the post below,( but did not work too...)
http://ccsinfo.com/forum/viewtopic.php?t=25961&highlight=&sid=862da1013c12444a90c72d7eb2fd61ca
CCS Version is 4.114, full code is below.
Any help from the experts would be really appreciated!
Thanks in advance!
Hugo

The line above doesn't make an array. It makes a pointer. If you want
an array, you need to declare it. Example:
There are several places in your program with false "arrays" like this.
You need to fix all of them. |

Just a comment on the update rate - I don't think I would go less than 250 ms. Less than that and even if the display can handle it, your eyes typically can not deal with numbers changing that fast. 500ms would probably be even better. There are some things like rpm that are often better displayed with an analog type meter (either a real one or an led type bar graph). 499, 500, 502, 498, 503 all in less than a second generally will simply confuse your eyes (and brain).

Mikey's right about the update rate. consider an LCD clock. The colon between the hrs and min flashes at a 1hz rate( 1/2 sec on, 1/2 off).Any faster and it'd be 'blurry'.LCD DVMs typically update at 3 HZ.
Same holds true for digital tachs, 1-2 readings per second.
It's a case where faster is not better.

Guys thanks for the replys, and I agree that 250ms should be fine in most of the applications... The point is that in that particular application I'd like to have the texts sliding in at least 200ms for a better and fast reading of the messages... and as you can see in the video (link above) it was working ok with 200ms update rate.... however after I've replaced to the new one I could not make it work again...Just do not know why or if it's related to the new controller S6A0069.
