Real Time Clock with Display Example

[korttoma]

I was thinking the same thing as @GREGL
I'm using the following to initialize my LCD:

LiquidCrystal_I2C lcd(0x27,20,4);
lcd.init();

Don't think I'm using the same Lib either.

I was just poking around on codebender and found the lib..but none of the examples use all these params.

IIRC ,I use a different lib...as my i2c lcd controllers are pretty old..byvac from memory.

Found the new liquidcrystal library while searching my display Funduino/1602.

The parameters are:

addr, en,rw,rs,d4,d5,d6,d7,bl,blpol

Tried the lib out in my setup and it seems to be working just fine so I think I will use that one to so that I can be on the same page as @hek

@korttoma

I has been checked in to master.

These OLED displays seem pretty cool also if the quality is ok and the library doesn't eat up too much space:

A lot more information being displayed in a much smaller package. Price is similar to the 16x2 LCD and they run on 3.3-5V apparently. Available as I2C also.

Hey maybe i can use this with the microview http://forum.mysensors.org/topic/48/idea-s-microview/

I have a couple of these (I2C) and they are great.
I have tried to use them together with a temp sensor but I failed doing so.
I was able to compile and upload the sketch but due to a lack of patience I did not investigate why it failed.
My gut feeling is that the problem was the use of too many string values...

I have a couple of these OLED displays on order, will see if I can get them working with the sensors.

Hi

Can you modify code for adding temp sensor to GW.
And may be display day of week.
Thank you.
