I compiled the bouncing ball code to ESP8266-12E board with no errors, but the OLED shows nothing, I replaced the OLED, checked wiring with no hope. please advice

Thanks

I did the following:
ran I2C scanner and reported I2C device at 60 , I2C bus connection is OK
ran bouncing ball code with two external 10K pull-up resistors (SDA and SCL)and one more time without them, OLED did not respond in both cases
measured voltage 5.03V
ran same code on arduino leonardo, OLED worked OK
I don't know what is wrong
