第一次移植LVGL-8.3.11版本，打开: #define LV_USE_GPU_DMA2D 1 编译后疯狂报错，但我看教程，STM32_DMA2D没有其他需要配置的地方，大神们救命，卡一天了

参考下我这个试试

基于V5，V6和V7的LVGL模板，驱动支持单缓冲，双缓冲和配合硬件消隐的双缓冲，以及电容和电阻触摸全支持（2023-07-19）

大神的这篇我很早就拜读了，我现在不打开LVGL STM32_DMA2D编译一切正常，官方的demo也都能正常显示，一打开LVGL STM32_DMA2D编译疯狂报错，可能是我的环境有问题吗

可以的话，升级到最新的LVGL，自带了ST的DMA2D驱动

使用这个编译 #define LV_GPU_DMA2D_CMSIS_INCLUDE "stm32h7xx_hal.h"
