LVGL+HAL库求助，在stm32cube创建freertos之后，运行键盘例程，按一个字母之后就卡死了，debug显示卡在prvCheckTasksWaitingT...

最近开始接触lvgl，用的是电阻屏和stm32f103zet6，在移植成功lvgl的情况下，再加入了freertos系统，跟着网上教程写好了基本代码，想着测试一下键盘输入，发现使用调度之后，屏幕点击一个按键之后就卡住了，debug显示卡在prvCheckTasksWaitingTermination()和prvIdleTask()之间来回运行，没有再返回心跳和键盘检测。跪求大佬们支招！

看看是不是内存不够，个人建议，既然都用上GUI了，什么还用STM32F103系列呢，建议直接用H7学习或做项目都非常合适

感谢提醒，目前手头只有这种开发板，只能精打细算地学了

使用LVGL，内存小是个麻烦的问题，建议关闭LVGL的各种炫酷特性测试。
