GLK12232 Vertical text

[tolrtd`]

During development, my GLK12232 started displaying the text in two vertical columns rather than in rows. I am using I2C. I am wondering if perhaps a stray string of bits triggered this mode. Any way to reset the device or solve this? The first column is directly in the middle of the screen and the second column is all the way to the right of the screen. It even auto-wraps around, although the characters show up overlapped.

Hi Tolrtd`,

Thanks for your question, sorry to hear you've been having some trouble displaying text on your GLK12232 using I2C. To reset your device, you will want to try the manual override outlined in your manual. Unfortunately, I'm not really sure which version of the GLK12232 you have, or the PCB revision, but if you can get that info to me I can outline the process should you be unable to locate it in a manual.

In addition, you may want to try putting the unit back over to RS232, wiping the file system, and uploading your bitmaps and fonts again using MOGD#. I know the jumpers can be a pain, but using solder instead of resistors can help, and this will provide a better understanding of the fault should the override bu unsuccessful.

If you have any further questions or concerns, please just let me know.

Thanks,
Troy

Troy,

Thank you for your advice- I used mogd.exe to reload the display. It seems that rewriting the fonts worked perfectly. Some stray command during my bit bashing must have changed an internal setting!

As always, thanks for the awesome products and even better support.
