国产MCU-CW32F030开发学习-ST7735 LCD模块
硬件平台
- CW32_48F大学计划板
- CW32_IOT_EVA物联网开发评估套件
- 0.96 IIC oled模块
ST7735 LCD模块
硬件接口使用的 2.54mm 间距的排针接口，这使用杜邦线进行连接.
| ST7735 | 参数 |
|---|---|
| 供电电压 | 3.3~5.5V |
| 驱动IC | ST7735 |
| 分辨率 | 128x128/128x160 |
| 尺寸 | 1.44 / 1.8寸 |
| 驱动接口 | 4线SPI |
引脚功能
| 引脚名称 | 引脚功能 |
|---|---|
| VCC | 电源正，3.3 - 5V，需要与通信电平一致 |
| GND | 电源负，地 |
| CS | 片选，低电平使能 |
| RST | 复位，低电平使能 |
| DC | 数据/命令选择，低电平命令，高电平数据 |
| SDA | SPI数据输入端口 |
| SCL | SPI时钟信号输入端口 |
| BLK | 背光，悬空使能接地关闭，默认上拉至3.3V |
