Is there any OLED dirver demo for 51822

[xtting]

Hi,

I need to implement 51822 drirver, is there some demo for that. By now I don't decide wich oled to use, and I don't know how many type of OLED at all. I wish a oled driver demo to let me know the basic information about how to use a oled.

Any one can give some document about oled, or some advice?

Thanks, Tao

Hi Tao,

first find out which controller your display is working with. E.g. the ssd1306 is very common on these cheap OLED displays you find on eBay or aliexpress.

Second, what is the interface of your display, TWI (I2C) or SPI? Then look at the data sheet of the controller (e.g. ssd1306) and send the appropriate commands via TWI or SPI to the display.

In this post devzone.nordicsemi.com/.../ you might find some ideas how to proceed and an example code as well.
