Quick update. I have tried communicating with the OLED Carrier board in 68XX-parallel (8-bit) mode, 4-wire SPI mode and 3-wire SPI mode. In each case, I can send it Command bytes but not Data bytes. It just seems like the data bytes are not latching. (I have done a bunch of logic checks on D/C). Has anyone had any experience with the new version of this board?
