Topic: LCD Time and Date stop working when Ethernet code used (Read 518 times) previous topic - next topic

Hi,

I am trying to display the Time and the Date from DS1307 on a Hitachi HD44780 and in the same time to control a LED from a Web page using the Ethernet shield of arduino. I can display the Time and the Date using a simple program but when i add the Ethernet function on the program I can only control the LED through the Ethernet but I do not see anything on the LCD. I attach my program to have a look. Please any ideas will be much appreciated.

Many Thanks!

LiquidCrystal lcd(12, 11, 10, 5, 4, 3, 2);


According to http://shieldlist.org the Arduino Ethernet shield uses digital pins 10, 11, 12, and 13 so you cannot use those for your LCD. 

Also, it appears that you are implementing the R/W connection for your LCD.  Are you sure that you need to do this?

Hi Don,

Thank you very much for your help. I changed "LiquidCrystal lcd(12, 11, 10, 5, 4, 3, 2);" with "LiquidCrystal lcd(8, 7, 5, 4, 3, 2);" and it worked.

Regards,
Steve
