UG-2864AMBAG01
|

==============
|
||||
|
||||
I purchased an OLED display on eBay. The OLDE 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
|
||||
the display contents:
|
||||
|
||||
Here is how I have the OLED connected. But you can change this with the
|
||||
settings in include/board.h and src/stm324fdiscovery-internal.h:
