Hi,
I'm trying to use this library to get my LCD alive.
I already have one working library in use but with this certain one, there is cool icon generator among which I find quite useful and that why would like to use this library.
I suspect that the issue is in library pin setup which I try to change, so that this library would work with the current HW setup.
I cannot print anything to the screen but I can adjust the contrast with the library command.
Even the example file dont seem to work.
So the question is, do I need to do some magic when i'm making changes to the library files, so that changes are among in the next compilation and test?
Some libraries have the pin call embedded, some don't. In the latter event, you call the pins in your programme and it's just a matter of making sure they agree with the wiring - and the wiring is kosher.
If the calls are in the library, they should be clearly identified and you can easily edit them using np++. I don't know what is so special about np++ but you are probably wasting your time using anything else.
Either way, I guess the only pin that is functioning at the moment is that which controls the contrast.
Thank you,
for the answer but I think you misunderstood my previous message.
I have tried to change the library codes with Notepad++, but it seems that my changes dont have any effect. So I was wondering if I need to do something additional, somehow load the changes in after making the changes to library files?
From this I take it that the pin call is in the library, i.e. the standard PCD8544. I think editing them should be all that is needed. Perhaps you need to restart the Arduino IDE, but I assume you have done that by now. Make sure the library is in the proper place and indeed replaced the old version.
Ok, thank you.
Is there someone on the forum who has this kind of LCD and could try this library?
There is example code among so it should be easy just to add the library and set the pin settings to the header file.
