This application note introduces the features and usage of the DD-12833BE-1A OLED display module, including EVK circuit schematics, pin definitions, timing characteristics, connection methods, power pins, usage instructions, and recommended initial code.
The DD-12833BE-1A is an OLED display module from Densitron Technologies. It is intended for integration with microcontroller‑based systems via various interfaces such as I²C, serial, and parallel modes.
The manual includes a full EVK schematic, symbol definitions, detailed timing characteristics for PC, serial peripheral, and parallel interfaces, power‑on sequence, usage instructions, and recommended initialization code. It also lists voltage pins (HV, LV, GND) and provides timing tables for signal setup and hold requirements.
| HV pin | most positive supply voltage |
|---|---|
| LV pin | logic supply voltage |
| GND pin | ground |
| PC Interface Tscl_cycle | 2.5 ns |
| SPI Interface Tsclk_cycle | 250 ns |
The RES# pin is the reset signal input; pulling it low initializes the chip.
Use the provided initialization routine, starting with the function void Initial_ic(void) that sets control pins and writes a series of command bytes.
