I'm trying a way to connect a OLED display with SSD1322 controller to the Flexbus peripheral of a Kinetis K60 microcontroller. This controller can be configured to communicate through a 6800 bus.
If I understood well, during write (from MCU to OLED controlled) operations, the SSD1322 reads data on the falling edge of the signal named E. How can I obtain this falling edge with Flexbus? Here it is the basic write operation of Flexbus peripheral.
During data valid interval, there aren't Flexbus signals that go down (falling edge). I could connect FB_CSn to CS of OLED controller and negated FB_CSn to E of OLED controller, but I will have at the same time a rising edge on chip-select and a falling-edge on E signal, and I think this dosn't work.
Have you seen this AN?
TWR-K60 + TWR-LCD can write and read to similar LCD controller in 6800 mode also.
