更隐蔽的是内存开销:u8g2默认使用页缓冲(page buffer)模式,对于128x64的OLED,一页就是128字节,但为了支持滚动和局部刷新,它实际会申请多页缓冲区,加上内部状态机、UTF-8解析器、坐标变换矩阵,RAM占用轻松突破2KB——这对只有20KB RAM的F103来说,意味着你连FreeRTOS的任务堆栈都得砍半。
实际上同样是128x64分辨率、同样是I2C接口,屏的驱动主控可能是SSD1306,也可能是SSD1315,甚至在某些批次里还能见到SH1106、SSD1316之类的方案。 屏上的发光面板只是“脸”,驱动芯片才是“大脑”,所有的初始化、寻址、滚动、亮度控制都是由这颗芯片完成的。
