Densitron DD-25664BE-1A OLED Display Module Application Note
The DD-25664BE-1A is an OLED display module supplied with an EVK evaluation board. It uses an 80xx‑parallel 8‑bit interface and provides pins for data, control, power, and reset. The document includes schematics, symbol definitions, timing charts, and wiring details for connecting the module to a microcontroller.
The note covers the pin functions (DO0‑DO7 data bus, CS#, P/S, WR, SD/C, RES, HV, LV, GND), timing parameters such as address hold and setup times, and provides example initialization code that sets scan lines, gray scale, luminance, and other driver registers.
