硬件连接如下图所示
很抱歉现在才进行回复，您可以把更早的日志发出来嘛？没有意外的话这应该是选错屏幕导致无法读到ID导致的

fatal error on thread: lcd_task?
应该使用--board=sf32lb52-nano_52j进行编译，有一些IO定义不同
你的意思是，如果不触摸屏幕的话，上面的内容可以一直刷新吗
是的，跑的example里的lvgl8 demo
目前的屏幕转接板没有添加上拉电阻，可能会导致I2C通信异常。可以尝试降低I2C速率到100k甚至更低。修改I2C代码速率的代码见https://github.com/OpenSiFli/SiFli-SDK/blob/main/customer/peripherals/ft6146/ft6146.c#L421
