This application note introduces the features and characteristics of the DD-12833YW-1A OLED display module, including interface specifications.
The document describes the EVK board schematic and pin assignments for the DD-12833YW-1A OLED display module. It defines the MCU interface pins, chip select, reset, power pins and explains how to select I2C, Serial or Parallel modes using SEL1 and SEL2.
Key sections include timing characteristics for the PC (I2C) and Serial Peripheral interfaces, the power‑on sequence, connection details between the OLED and EVK board, and a recommended initial code example for bringing the display up and configuring basic functions.
