Newbe - LCD Blank

[MDN]

Hello,
Just received my RA and was able to get everything setup and working out of the box.
I am using a MAC so after tracking down where all the folders were suppost to be I was able to get the Wizard running as well.
Ran through the Wizard and everything went great - uploaded the code, all went well. Wizard said "Success", all good right.
Wrong -
My LCD is blank, I can see the backlight is on but cannot read anything on the screen. I think the RA is working because if I press the joystick I can hear a relay click. I am assuming this is "Lights On" the first menu option.
I tried loading the Preloaded code back on, it loaded but same LCD problem.
Anyone have any thoughts ?
Thanks in advance,
Mike

Your library version? Try naming the current library folder to libraries.old and downloading the Mac installer off reefangel.com in the download section. Install. Upload again and see what happens.

[MDN]

Thanks for the quick reply.
Libs are 1.0.2 and I just downloaded and installed everything tonight - but I can try again.

Oh never mind then. Just a thought. Roberto will help you when he can. He always knows the answer

[DrewPalmer04]

A good place to start is to share the code you'd like to upload and maybe he can spot the reason

No worries, I was just grabbing the code as you were typing. Thanks

Remove
ReefAngel.AddStandardMenu(); // Add Standard Menu

Upload then see If you get the simple menu to display.

[MDN]

Removed:
ReefAngel.AddStandardMenu(); // Add Standard Menu

Again, uploaded fine, RA reboots - no display. Just the backlight on.

[DrewPalmer04]

Ok sorry it didn't work. Roberto will know...

Try this:
Locate the file ReefAngel.cpp. It's located in Documents\Arduino\libraries\ReefAngel folder.
Open it in notepad or your preferred text editor.
Delete this line:

Code: Select all

    SendCMD(SWRESET);

Save the file.
Upload your code again.

[MDN]

Rob,
I do not have that line in my ReefAngel.cpp file. I have looked and done a search for it.

Thanks
Mike

[rimai]

Ooops... My bad...
Wrong file.
Documents\Arduino\libraries\RA_NokiaLCD\RA_Nokia.cpp

[MDN]

Eureka !!!! Perfect, LCD back online. You are the man.
So, does this mean the Lib's need updated and until then make this change if I reinstalled the software ?

Thanks
Mike

[rimai]

Yes, I'll work on libs update tonight.
Thanks for reminding me about this issue.

I received my RA today and saved my configuration from the wizard and now my LCD is blank. I tried the fix suggested by Rimai and no luck restoring the LCD. Can anyone assist?

[rimai]

Libraries updates were pushed already.
Your Arduino IDE should detect and update itself automatically. It may take until tomorrow to auto-detect.
The auto-detect only works once a day to avoid nagging prompts.

[MDN]

You updated this file:Documents\Arduino\libraries\RA_NokiaLCD\RA_Nokia.cpp - correct ?
Once I removed the line, I closed the Arduino app and reopened it. Opened the code that the wizard created for me, verified it and then uploaded it.
I left the line :ReefAngel.AddStandardMenu(); // Add Standard Menu in the code, I did not remove it as suggested in an earlier post.

[MDN]

Roberto,
Did you update the MAC lib's as well ? I see the windows installer is 1.0.2a but the MAC is still 1.0.2

Thanks
Mike

[rimai]

The libraries will auto-update by itself when you open Arduino.
If Arduino was already opened today, you will only see the auto-update check tomorrow.

[rimai]

If you wish to force the check, you need to hack the preferences.txt file:
http://arduino.cc/en/Hacking/Preferences
And change the update.last to:
update.last=1000

[MDN]

Thank you Sir.

Instead of waiting for the auto update from my Mac I installed the software on my PC and was able to push the new code to the controller and issue resolved. Thanks for fixing this issue!
