![]() This looks really crazy and not so useful. In my LCD, I don’t like the fact that about 1/3 of LCD is yellow when pixel is ON and the rest is blue. Parallel interface is really not necessary here because of small amount of data to be transfered since each pixel is a bit in a bytes area. Driver itself allows also some other communications like 3-wire SPI or 4-wire SPI as well as 6080 parallel interface any maybe more. The heart of this OLED LCD is SSD1306 driver. Probably I should make it using I2C DMA transfer. But anyway, for having this LCD just to showing small updates and notifications for users in your project, I2C is still nice. To update full LCD, there are 1024 bytes of data to be transfered. ![]() I2C communication from my module isn’t really powerful because of slow I2C, even at 400kHz. These little, small and with nice contrast devices are really great.
