More I/O pins, more memory. To use all the features of that LCD shield (touchscreen and SD card reader) you need an Arduino Mega smiley


If you buy a Arduino Uno, then you need this shield to connect the display:

But then you won't be able to use all the features of the LCD.

I recommend the Arduiono Mega so no problems smiley-cool

If you use 74HC595 shift registers, you could try this one

NP, can I suggest buying this LCD, because it's the same thing but cost less:

Or, if you didn't buy the arduino already, buy this pack:

http://www.sainsmart.com/sainsmart-mega2560-board-3-5-tft-lcd-module-display-shield-kit-for-atmel-atmega-avr-16au-atmega8u2.html

I bought the same pack on ebay for 35€ (~45$) smiley

Is there a string longer or shorter than 3 characters in his code? No so why are you discussing things unrelated to the question...
530  Using Arduino / Displays / Re: LCD TOUCH HELP on: January 08, 2013, 02:24:46 pm
Yes, but it is recommended to connect it with the help of this adapter shield:

531  Using Arduino / Programming Questions / Re: Text Array on: January 08, 2013, 08:09:18 am
Or,
Code:
char sNames[7][4] = {"Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sun"};

Je pense que c'est la librairie UTFT qui est lente, elle est conçue pour fonctionner avec pleins d'écrans et donc utilise une méthode universelle pour remplir l'écran: pixel par pixel.

Je ne sais pas quel contrôleur ton écran utilise, mais si tu regarde son datasheet tu y verra probablement une méthode nettement plus rapide pour effacer (ou remplir) l'écran. Maintenant pour convertir ce qui est dit dans le datasheet, en code C... smiley-grin

pYro I don't really care about an oscillator (or whatever it is), I'm more interested about testing your fast library and see the differences (in the code) between it and UTFT. I'm stuck converting what I can read from the SSD1289 datasheet to a C++ code (timing, etc)...Your lib will teach me a lot, I think smiley
535  Using Arduino / Programming Questions / Re: Add to an integer on: January 01, 2013, 06:20:26 pm
You have few choices:
Code:
i = i + 1;
i += 1;
i ++; //post increment
++ i; //pre increment

Ok thanks, can I do something else, like for example, wire the SQW pin (set to 1Hz), to a relay's low level input, to turn on/off a light every seconds, without the need of the Arduino? Can it be used as an alternative to a timer such as the 555 timer chip? Sorry if my questions sound stupid smiley

Ok thanks I understand this but I'm very beginner about hardware, what I don't understand is, what those pins can be used for? Can you give an example?

Want!

Hello pYro 65,

Good job! Once you fix the errors, can you describe precisely how you did the whole thing?

Thanks smiley

Hello all smiley

I bought a DS3231 RTC breakout board:


I've read DS3231's datasheet, but I'm still wondering what are those pins SQW and 32Khz. Can someone explain what they are, and how useful they can be, what is their typical use, etc...

Thanks in advance smiley
