I purchased an OLED display on eBay. The OLED is 128x64 monochrome and
|

is based on an UG-2864AMBAG01 OLED controller. The OLED can run in either

parallel or SPI mode. I am using SPI mode. In SPI mode, the OLED is

write only so the driver keeps a 128*64/8 = 1KB framebuffer to remember

Darcy Gong recently added support for the UG-2964SWEG01 OLED which is also

an option with this configuratin. I have little technical information about

the UG-2964SWEG01 interface (see configs/stm32f4discovery/src/up_ug2864sweg01.c).
