用STC32G144K246的63例程 | 已解决，取模软件，新旧风格
用STC32G144K246的63例程【63-QSPI-TFT_DMA_P2P外设到外设_显示视频级动画效果程序-ILI9341】
把屏改成V7789, 8位数据P2后黑屏(背光是亮的),
不知问题出在那?
请大家指点

通常背光由单个引脚控制移植没问题
可尝试调整通信速率 可能得比较TFT控制器的数据格式
另外单片机的外设也可能配置上有区别 我是新手不知这搞{:zhemo:} 1.向屏幕厂要点屏例程，对比初始化序列
2.检查接线
3.逻辑分析仪抓屏幕侧波形，对比初始化数据
请教大家,这样显示问题出那里? 智*** 发表于 2026-5-25 11:21
请教大家,这样显示问题出那里?
感觉CS或其它线上有干扰，打乱了传输节奏。
先试下逐帧刷纯色，量下CS WR RS这些关键信号上有没有毛刺。
帮我看下怎回是,W25QXX我只烧入了13张图片的BIN,是不是还要烧图片尺寸的参数呀? 智*** 发表于 2026-5-25 14:35

初值看看？
要么仿真问题打印出来看看，或者QSPI RAM越界覆盖了？

这我不知在那改,请指点{:baoquan:}这是ST32G144246的63例程,不存在你说的吧?
