基于idf-5.0框架的rgb_panel示例修改, 手里的显示屏驱动芯片为ST7701S, 接口RGB565, 分辨率800*480[问题] 使用的防撕裂方式为两个信号量"sem_vsync_end, sem_gui_ready", 与idf示例相同, 双buf缓冲. 问题是"LCD_PIXEL_CLOCK_HZ"这个参数目前限制在了12MHz, 超过这个值后显示的画面会发生器偏移(右移), ...

SPI LCD 引脚连接 8080: 这里讲一下8080接口接线: 1,2为背光灯控制,1为背光灯阴极,直接接地,2为阳极,接esp32s3的io;电源只需接4脚3.3v;7、8、9、10分别接入esp32s3对应io,11脚RD最好接3.3v拉高(看其它帖子说RD浮空会导致花屏);同时笔者由于初次接线时没有注意到12-19引脚对应的是D7-D0导致数据线12对...
