Oled display not working, show Black Screen after-show dots

luqman

Hi.

I'm new on this form and also new on nrf dev board. I want to use OLED with nrf52832 using Twi / i2c. I grab some code on Github https://github.com/monpetit/nrf52-spi-i2c-master-ssd1306

which is running on my SDK 16.0. But the Oled now shows not any full response on this code just show some dots on the screen when I upload the code and after that, it's going dark Disappointed

I try using the TWI_scaner example which shows me the address 0X3C

as well but I don't have a logic analyzer to check the states of pins so if one knows the solution please let me know. 

thanks.

    Hi!

    We could try to give you some guidance here. However, some mode details are needed. What is the part number for your display? Are you using an 128x64 OLED with the SSD1306 driver? Do you have any image of the display available? Which pins are you using? Which voltages have you set the project up with?

    Is your project relying on using specifically nRF5 SDK 16.0, or have you considered using the latest nRF5 SDK? Or have you considered moving to  nRF Connect SDK? The nRF Connect SDK has samples and drivers available for several displays.

    Also notable is that Jimmy Wong has set up the mentioned OLED displays with nRF 52 DK and nRF5 SDK v15.3. Perhaps you could try SDK v15.3 first to confirm this is working?

    Yes I'm using 128x64 OLED with the SSD1306 driver The link of the code is given above, 
    Not really, depend on 16.0 SDK as the above sample use SDK 16 that's why I jumped to it.
     I checked that example of too with SDK 15.3 but it does not show any response too. I'm new on nrf maybe I'm wrong at some point but after uploading code not show any response on led, 
    I'm use 
    Sck  27
    sda.  26 pins 
    It returns the address of old when I run twi scanner example..i try that nrf connect too but I don't get why this couldn't be show response

    Thank you for sharing the details.

    Our FAE Jimmy Wong has made an example with 'OLED display support for nRF52 Series'. The code is on github and here is his blog post on the project.

    This should work on nRF52832 as well.
