    Hi! Last year, I was looking for a display to show different information on my home theather computer. I wanted a display to fit in a 5" 1/4 bay and no LCD technology as I don't want backlight that lights all my room when I watch a movie (high contrast required). Then I discovered the 3.2" monochrome OLED display ER-OLEDM032 based on SSD1322 chip. Support in Aida64 was implemented by Fiery. It looks great! Infinite contrast of OLED technology is perfect. 4 different models exist for 4 different colours. Blue: Green: White (what I chose): And yellow: Dimensions: 4 protocols are available. Protocol to be used is set using bridges on the display PCB. 6800 8-bit parallel 8080 8-bit parallel 3 wires SPI 4 wires SPI 6800 and 8080 are obsolete as we don't use anymore parallel port. I chose 4 wires SPI rather than 3 wires SPI because communication speed is a bit higher. To convert USB to 4 wires SPI, I used a FTDI UM232H-B-WE breakout module based on chip FT232H. Here is the schematic of connections between USB breakout module and OLED display:
