SSD1306 oled with NRF52840

Rohit Gujarathi

Hi everyone,

I am not able to get  ssd1306 working with zephyr. i am trying with nrf52840. The same setup works with adafruit library but not with zephyr. I am using I2C and get ACKs for all the data and commands but nothing gets displayed. I used a logic analyser to see what difference is there and saw a few differences in the commands so i modified the ssd1306 driver for zephyr to align with what adafruit library was sending but still nothing is displayed on the oled. can someone please help. i have attached zephyr logs, modified driver and logic analyser comparison csv.
