问答

前端时间在调试 GD32H7 ,可是发现使用TLI 时 还是存在问题，调了很久最后放弃了 由于H7 的架构 有多种内存块， 使用不当就存在问题 开始使用外部RAM存放显存， 一直没成功， 后来没办法使用内部RAM 单显存测试，还是不行，屏幕显示经常有马赛克， 感觉这个TLI 配置起来太麻烦了 有TLI 有2个图层 ， 使用的时候 即使用一个图层 ，2个图层还是必须要都要配置，不配置还不行 因为2个图层后面有个混合 更新输出的时候 也比较扯。 在使用LVGL 时，使用单格全屏显示缓存，我配置了TLI 的2个图层，仅使用1个图层输出， 然后再输出时使用 [color=#dadada][backcolor=#1e1e1e][font=Consolas,][color=#dcdcaa]tli_reload_config[/color][color=#b4b4b4]([/color][color=#dadada]TLI_FRAME_BLANK_RELOAD_EN[/color][color=#b4b4b4]);[/color] [/font][/backcolor][/color] 来触发TLI更新输出，但是有问题，无法显示， 这就很扯，首先也不知道什么时候更新完成？然后调用这个没有效果 有没有H7 的LGVL的例子学习一下？
