This application note introduces the DD-32645C-2A, an OLED display module with EVK board. This document details the module's features, pinout, and usage.
This guide provides an overview of the DD-32645C-2A evaluation board (EVK) and its connection to an 8080‑parallel interface MCU. It includes the schematic, pin definitions, timing characteristics, and wiring instructions for the OLED display module.
The document also supplies a recommended initial firmware routine that configures the display driver and demonstrates how to write commands and data to the sensor module. Sample code snippets illustrate the required pin toggling and initialization sequence.
