lvgl_benchmark运行问题(已解决）

lvgl库aithinker_Ai-M6X_SDK\examples\lvgl\demos文件夹下有benchmark例程，我用1.3寸LCD跑了一晚上，程序一直莫名奇妙卡死，而且都是在不同的地方卡顿，我把帧率从50fps降到18fps，也修改了LV_MEM_SIZE，LV_LAYER_SIMPLE_BUF_SIZE，LV_LAYER_SIMPLE_FALLBACK_BUF_SIZE 等参数，也没有一次完整跑完，还是在不同的地方卡死。感觉调整参数没有规律可循，特地来问问大佬。

原因：见C站 [LVGL]移植记录：v8.3 运行demo跑飞进入HardFault_Handler 学习记录_1_lvgl hardfault_handler-CSDN博客


解决方法：
堆栈溢出，增大Stack Size
具体操作：
M61进行开发底层使用了操作系统，使用了freertos，并不是裸机编程，而freertos有自己的一套内存管理，使用者只需要对FreeRTOSConfig.h文件根据自身需求修改堆栈大小即可。





修改为：

1. #define configMINIMAL_STACK_SIZE                ((unsigned short)256)   
   
2. #define configTOTAL_HEAP_SIZE                   ((size_t)128 * 1024)

复制代码

结果：


说明M61的性能还是很强大滴

不错呢，学习了

没有在M61上具体玩过这个lvgl，不太清楚。不过也用的时候可以参考下你的操作。就不用从零开始了。

你看上面都是来水积分的，不像我是真不知道，来看看

看看小泽的

小泽大佬的有介绍
