"中景园电子0.96OLED显示屏的数据手册1，主要涉及STM32微控制器的应用" 本文档是关于中景园电子0.96英寸OLED显示屏的数据手册，该显示屏由Golden Morning Electronic公司批准并适用于STM32微控制器。手册详细介绍了显示屏的基本规格、机械规格、活动区域、引脚定义、电路结构以及光学和电气特性。 1. **基本规格** (1.1~6) - **显示规格** (1.1): 这部分包含了显示屏的物理尺寸、分辨率、显示模式等基本信息。0.96英寸的OLED显示屏可能具有64x128像素的分辨率，支持灰度显示。 - **机械规格** (1.2): 描述了显示屏的物理尺寸、安装孔位、厚度等，以便于在硬件设计中正确集成。 - **活动区域/内存映射与像素构造** (1.3): 详细阐述了显示区域的布局和内存如何分配来存储图像数据。 - **机械图纸** (1.4): 提供了显示屏的精确尺寸图，用于精确安装。 - **引脚定义** (1.5): 列出了显示屏的所有接口引脚及其功能，如电源、数据线、控制线等。 - **模块框图** (1.6): 展示了显示屏内部的电路结构，包括外部供电的VCC和内部DC/DC电路的布局。 2. **最大额定值** (2) - 部分内容提及了VCC电源的两种情况：一是由外部提供（1.6.1），二是由内部DC/DC电路生成（1.6.2）。这涉及到显示屏工作的电压范围和稳定性要求。 3. **光学与电气特性** (3.1~18) - **光学特性** (3.1): 包括亮度、对比度、视角、响应时间等，这些决定了显示屏的视觉效果。 - **直流特性** (3.2): 描述了工作电压、电流等在不同条件下的典型值和最大值，对于电源设计至关重要。 - **交流特性** (3.3): 可能涉及驱动时序、刷新率和信号电平，这些参数直接影响显示屏的显示质量和稳定性。手册中的一个重要变更记录是亮度寄存器（0X81）的参数修改，原本的0XCF更改为0X66，这表明制造商可能调整了显示屏的默认亮度设置，以提高能效或适应不同的环境光线条件。此外，RIREF的阻值也从390K变为910K，这可能会影响内部电路的电压调节，从而影响显示屏的亮度和颜色表现。这份数据手册为开发人员提供了全面的技术指导，以帮助他们在基于STM32微控制器的项目中正确地使用这款0.96英寸OLED显示屏，确保其性能达到最佳状态。

This pin is Data/Command control pin. When the pin is pulled hi

g

h, the input a

t

D7~D0 is treated as display data. When the pin is pulled low, the input at D7~D0

will be transferred to the command register.

When the pin is pulled high and serial interface mode is selected, the data at SDIN

will be interpreted as data. When it is pulled low, the data at SDIN will be

transferred to the command register. In I

2

C mode, this pin acts as SA0 for slave

address selection.

For detail relationship to MCU interface signals, please refer to the Timin

Characteristics Diagrams.

This pin is MCU interface input. When interfacing to a 68XX-series

microprocessor, this pin will be used as the Enable (E) si

g

nal. Read/write operation

is initiated when this pin is pulled high and the CS# is pulled low.

When connecting to an 80XX-microprocessor, this pin receives the Read (RD#)

si

g

nal. Data read operation is initiated when this pin is pulled low and CS# is

pulled low.

When serial or I

2

C mode is selected, this pin must be connected to V

SS
