18f2550 and LCD1602 blank
Hello

I've serched in google and found that (i think) there is a problem in the IDE that makes LCD and 2550 not working togheter?

Today I tryed and for me, it didn't worked.

I have a 18f2550 with bootloader v4.14
Pinguino x.4 rev999.
I tryed the examples clock and HelloWorld.

Double and triple checked the connections, everything is like the examples.

I run pinguino on W7 SP1 ultimate.
The LCD is a HD44780 compatible.

The screen lits, the pot regulates the contrast and nothing more...

Is there any workaround?

Thanks
Fernando

Why not try with the last version of the IDE and libraries ?

It is easier to complain than it is to do, but it is better to do than it is to complain.

Thanks for the answer.

I've tried, but all errors...

First.
With admin acount, i've runed pinguino-11.2015.02.02-setup.exe, pyside complaints that it can't find python27, and i've installed, it is in c:\python27, and in environment variables too.

I've searched for resolution, but i can't get it right.

Next everything installs, but as i double clic the pinguino icon, a prompt apears and desapers very fast, and nothing...

What can i do?

Tanks again.

Well, sometimes that old rule still is works.


I uninstalled everything, restarted the computer, run pinguino installer, and only 8bits and 32bits compiler gave error.

Restarted the installer each time, and bingo!

Now have to try the lcd if it works.
