Oled remains blank #1

This is a great project! I happened to get a T-beam and TTGO Lora32 with Oled. The T-beam is talking to the Lora32, I can see the gps on the serial monitor, but it isn't appearing on the Oled. Is there something I should check? The Lora32 says T3_V1.6 20180606 on the PCB.

Fixed: On the V2(?) V3(?) I had to change the code to

define OLED_SDA 21

define OLED_SCL 22

define OLED_RST 16

The above pin assignments worked for my TTGO Lora32 with Oled. However the text is missing every other line of pixels. I have two identical boards and both behave the same.

My google fu is failing me but thanks for the info.
