SSD1306, DIGISparkOLED not working with teensy3.2 - arduino

Question

OLED display is not working with teensy3.2 board, but it is working fine with arduino UNO with the same code as below:
#include <U8glib.h>
U8GLIB_SSD1306_128X64 u8g(U8G_I2C_OPT_NO_ACK); // Display which does
not send AC
int frame=0;

Their are no compiling errors. The OLED is not even turning on. AND on scanning the address comes out to be 0X3C.I have searched a lot on google but i think theirs and issue in I2C communication.
Please help me out.

Answer 1

#vasu Hi I had the same problem but please also check for any hardware faults before following my answer.
The oled display I bought only had VCC-GND-SCL-SDA. So I don't have a reset PIN here.
But the oled library initially tries to pull the reset PIN high on startup. Since I don't have a reset pin, it sits there and waits for a reset HIGH. So in order to initialise your oled display without reset pin then try this in your Arduino sketch file
//1-->Manually set HIGH to digitally assigned reset pin
pinMode(A4, OUTPUT); //A4 is reset pin assigned programmatically (for example)
digitalWrite(A4, HIGH);
//2-->Try changing your init to this
U8GLIB_SSD1306_128X64 u8g(U8G_I2C_OPT_NONE);
//As this will be the right one to define from the user manual shown in the link
//https://reprap.org/forum/file.php?267,file=54605
Try the above and let me know how it went.
Cheers
