in ESP8266 OLED Starter Kit by (550 points)

I've got the ESP8266 OLED starter kit with the 0.96" screen and it works great!

I puchased a 1.3" screen to make it a bit easier to read.

The included .96 Screen had VCC GND SCL SDA

The new screen has  VDD GND SCK SDA

Connected to the same code, I get some of the image, but most of the screen is scrambled:


Does anyone know if this is a sign of miswiring (Maybe I need a pull up resistor?)

Or is a sign that I need to change the driver or it's configuration (maybe SCL != SCK)

Or could it be a bad display?

Hi Jack

The scrambled screen indeed indicates that you are using the same driver for the bigger screen as you used for the 0.96". The 1.3" most certainly has a SH1106 chip so you should use this driver:

Have a look at this section which explains exactly what you'll have to change:


Kind regards,
