OLED display is showing garbage

[YASH]

Hi All,

I am working on nrf52840 pdk, where i can see that my OLED SPI 128x32 display isn't displaying properly and displaying only garbage value.

Although the same code is running on nrf51422 dk, and i have mapped the pins with respect to nrf52840 also. I am using sdk 12.2.0. What could be the possible reason behind my display showing garbage value?

Thank you in advance.

well nobody can really help you because all you've posted is a qualitative description of the problem, no code, no debugging output, no model of the display, indication of what you've tried, logic analyser output or in fact any information which could lead to someone being able to hazard a guess what's wrong.

Hello, sorry for the insufficient information. I have uploaded the photo of my display. Although i don't have a logic analyser available right now. Thank you.

By the way i doubt if its happening because of different clock speed in nrf52840? But the thing is that the SD card reader is running perfectly as it was in nrf51422 without any change.

Still it's not enough information. You need to provide what RK asked: debug output, code, display model. How did you debug.
