Clock and calendar using Arduino due internal RTC and I2C LCD display

Показать описание

This short video introduces us to - 1) Real time clock RTC of Arduino due to get date and time. No need of external RTC chip/board (2) Running I2C LCD display on arduino due using Arduino IDE version 1.6.6 (3) Displaying fixed text and scrolling text. (4) Fixing issue of only one character being displayed on LCD displays, especially using higher version arduino IDE.

I downloaded the RTC library, but it requires a file called chip.h which I discovered in it's turn requires endless other .h files, so basically, the sketch is unusable !

Hi!did you separate the supply of the LCD from the due? LCD SDA and SCL is still connected to the arduino due this going to work?

I also can't use this library due to the missing chip.h file :/ Any solution to this?

Exactly what I was looking for!

Just a small problem, time is really going too slowly ... (3 sec for one).

Any idea?

Thank's

What if I need this display to be seen from 10 meters ?? can I get other display boards compatible with raspberry pi ??

freemanfreed

It kinda works ... well atleast it doesnt shows any errors inside the Sketch but neither it show Anything on the LCD do you know whats the problem with that? or why that is or how to fix? Im realy sorry but im kinda confused at the moment pls help ^^ + it always kicks the Arduino out of com4 so i have to replug it-.-

aliegeus.

Are you sure that using 5V I2C will not be damaging the Due?
