Solution to the character 10 problem

For any who have a similar issue to me, in that sending character 10 displays a 13 pixel wide bar, the solution was obvious once I looked at the numbers, 10 being the line-feed character and 13 being carriage-return.

The linux terminal I was using to write to the display (/dev/tts/0 in my case ...

More detail on bar graph characters.

The documentation for the LCD2041 lacks any detail of how the horizontal bar characters are made up or how the characters are used, so some questions:

1)
Is it possible to display horizontal graphs in both directions at once? uProject's demo would imply it should, but doesn't display properly (this ...

I don't know about the other because it's not in my possesion at the moment. I'll get a returns number when I've bought some more in to replace this one, thanks.

I can confirm that uProject also has the problem with the horizontal bar graphs being incorrect - during the demo the bars jump erratically. The right-to-left bar graph is even more screwed up.

Testing with exact commands reveals that when doing a left-to-right bar graph (direction 0), sending ...

I'll try uProject as soon as I can, in the meantime I think I'll just buy another display and see if it's the same.

With regards to "factory reset", is there such a function available?

Thanks for your help

Given that I can do pretty much everything else this display is capable of flawlessly, I doubt it's my inability to send the number 10 :p

Is there a way for me to reload the unit to it's default configuration and try that? Failing that can I please send this back to you for exchange?

I just realised a typo mistake in my original post. I meant bank 1, not 0, in the following part:

I have tried setting custom horizontal bar characters by programming bank 0, but even after loading them instead of the defaults I get the same result. I have only set the first 5 characters of bank 0 ...

Is the result supposed to be sent back down the serial line or displayed on the LCD screen?

I get nothing back when I read after sending that command, but when I do read, a "V" is printed on the display, which would imply the version is v5.6

LCD2041 internal memory corruption?

Hi,

I bought 2x LCD2041 from you a few months back for prototype work, and I now want to use them in the final product, however..

The two I have work flawlessly for 99% of operation (RS232, 19200 baud), but I have problems whenever I try to send the value 10 as part of a command.

The commands ...
