LM3S811, mirror reversed text on LCD display

Posted by Joe Flowers on January 15, 2012
Text comes out mirror reversed on LCD display of LM3S811.

I'm using a new LM3S811 with FreeRTOS and running the demo that came with FreeRTOS,
."\FreeRTOS\FreeRTOSV7.1.0\Demo\CORTEX_LM3S811_GCC".

I compiled with the latest version of the Lite Sourcery CodeBench (gcc) Lite.

Any ideas what is causing this mirror imaged, reversed text?

Thanks!

The demo for that board was written on one of the original hardware versions. I believe the OLED display (or the controller thereof) has been changed several times since then - so it might just be a case of grabbing the latest version of the Luminary/TI display driver from their StellarisWare package.

Regards.

Hi Richard,

Thanks a lot for your pointer. I have been trying and compiling other code distros for this but no luck yet.

I assume by the display driver you mean these files are what I need to change:

osram96x16.c
osram96x16.h

"osram96x16.c - Driver for the OSRAM 96x16 graphical OLED display."

Thanks Richard!!!

I know it is a different board, but if you search for the term "Note for LM3S2965 and LM3S6965 users" on the following page, you will see that, for that board at least, the name of the driver file changed too. The same might be the case for your board.

Richard,

Thanks a ton for your kindness and help.

I think it would be best at this point if I switch gears and start working on the boards that are more suitable to our final product, the LM3S8962 & the LM3S9D92.

I hope these don't exhibit this same behavior or I'll have to revisit this problem.

Thanks again Richard.
