一、引言

介绍SH1106 OLED屏幕的基本特性：单色显示、低功耗、高对比度，常用于物联网设备。
简述ESP-IDF框架的优势：开源、高效，支持ESP32系列芯片。
文章目标：引导读者从零开始，实现SH1106屏幕的初始化、文本显示和图形渲染。

二、准备工作

硬件需求清单：
- ESP32开发板（如ESP32S3 N16R8）。
- SH1106 OLED屏幕模块（常见尺寸：1.3寸（4针IIC协议），128x64像素）。
- 连接线材：杜邦线、电源。
- 其他：面包板（可选，用于测试）。
软件需求清单：
- ESP-IDF开发框架（最新稳定版本）。
- 开发工具：VS Code以及esp扩展，串口调试工具。

三、设置开发环境

安装和配置ESP-IDF：
- 步骤：下载ESP-IDF，设置环境变量，验证安装。
- 提示：使用官方文档确保兼容性，需要安装Python环境。
在VS Code中添加ESP-IDF扩展支持：
- 方法：点击VS Code左侧扩展，搜索Embedded IDE并安装，与ESP-IDF环境进行配置。
- 注意事项：配置比较繁琐，建议找相关文章参考。

四、硬件连接与接口选择

SH1106接口类型：
- I2C接口：常用、简单，适合初学者。
- SPI接口：高速，适合高刷新率应用。
连接步骤：
- I2C模式接线图：ESP32的SDA引脚连接SH1106的SDA，SCL连接SCL，VCC和GND供电。
- SPI模式接线图：ESP32的MOSI、SCK、CS引脚对应连接。
- 安全提示：避免电源反接，使用逻辑电平转换器（如需要）。
- 注意事项：模块必须和单片机共地否则会出现传输数据不稳定现象！

五、代码实现步骤

项目结构设置：
- 创建新工程：使用ESP-IDF模板。
核心代码编写：
- 初始化I2C/SPI总线：配置引脚、设置时钟频率。
- SH1106初始化函数：发送配置命令，设置显示参数（如对比度、扫描方向）。
- 显示基础功能：
  - 文本显示：实现字符串渲染函数（例如显示“Hello, ESP32!”）。
  - 图形绘制：支持画点、线、简单图形。
- 代码优化：添加缓冲机制减少刷新延迟。
示例代码片段：

六、测试与调试

编译与烧录：
- 步骤：使用idf.py build编译，idf.py flash烧录到ESP32。
- 常见错误：引脚配置错误、驱动未加载。
功能测试场景：
- 基础测试：显示静态文本，验证连接。
- 高级测试：动态更新内容（如传感器数据显示）。
调试技巧：
- 使用串口日志：输出错误信息排查问题。
- 常见问题解决：屏幕无显示（检查电源、接线）、显示乱码（检查初始化序列）。

七、扩展应用与优化

高级功能实现：
- 多屏幕支持：驱动多个SH1106屏幕。
- 低功耗模式：利用ESP32的睡眠功能降低能耗。
- 图形库集成：结合LVGL等UI框架创建丰富界面。
性能优化建议：
- 减少刷新频率：使用局部更新策略。
- 内存管理：优化帧缓冲大小。

八、结语

总结关键收获：强调SH1106在ESP-IDF中的易用性和适用场景。
进一步学习资源：
- 推荐文档：ESP-IDF官方文档、SH1106数据手册。
- 社区支持：GitHub开源项目、论坛讨论。

使用burp suite拦截抓包

页面一闪而过是PHP执行完输出flag后立刻发送302重定向跳转，浏览器直接跳过中间页面。切换标签到代理（proxy）子标签HTTP历史，找到目标URL，双击这条请求。切换至响应（response），在响应头下方的文本可以直接读取flag。- Preserve log会缓存所有请求完整响应；- Burp拦截直接阻断跳转，完整留存输出文本。- 普通刷新会丢失中间页面内容；在burp的内嵌浏览器打开。

Proteus9 ， STM32f103c8t6（72Mhz）虚拟串口通信配置
