Today i found ozoled and tinyozoled and converted the libs will try to work with it.
Has any one a working example?


the hello world example for ozolib is

#include <Wire.h>
#include <OzOLED.h>


void setup(){

OzOled.init(); //initialze Oscar OLED display
OzOled.printString("Hello World!"); //Print the String

}

void loop(){
}

Try the attached library.
B4X:
Sub Process_Globals
   Public Serial1 As Serial
   Private oled As SeeedOLED
   Private wire As WireMaster
End Sub

Private Sub AppStart
   Serial1.Initialize(115200)
   Log("AppStart")
   wire.Initialize
   oled.Initialize
   oled.ClearDisplay
   oled.SetNormalDisplay
   oled.SetPageMode
   oled.SetTextXY(0, 0)
   oled.PutString("Hello World!")
End Sub

It works fine with ardruino Uno board but not with mega 2560 !!! why ???
i do nothing wrong there are only 4 cables + - , analog4 and analog5 !!!
Is it possible to select custom analog pins for a4 and a5 ?

Strange thing....
The above code works only if i run the Hello World example with ardruino studio and after that the example you wrote with b4r
If i unplug the power and compile again the code with b4r the oled screen stays blank !!!

This is the code i run:

#include "U8glib.h"

// setup u8g object, please remove comment from one of the following constructor calls
// IMPORTANT NOTE: The following list is incomplete. The complete list of supported
// devices with all constructor calls is here: https://github.com/olikraus/u8glib/wiki/device

I tested the code with ardruino studio and b4r. Nothing off the above works with mega 2560!!
I would like to find a solution for my small project using the oled with mega 2560.

After some test i found out that on mega 2560 i have to use pins 20 and 21 instead of a4 and a5. So it works on mega also.
But only with u8glib !!!!

And so it looks like if i run after the code with rSeeedOled lib.
If i unplug the cable and run again the code with b4r it will not work anymore !!
(The font size is also very small)

Try the attached library.
Hi Erel,
I've tried your code in #4 but i've got that error message listed blow, i ran another C++ example from this page in Arduino studio, and it worked very well. kindly tell what to do. one little note, the rTFTv2 library does not have graphics methods like the original U8glib!

Thanks

Hi,
compiled an uploaded ok (error because of duplicated cpp and h files in lib folder), but screen is blank now, i noticed that my tft has 2 extra pins labeled RES and DC, in C++ example page they are wired to pin 3 and 2 on arduino UNO.
