I want to learn how to develop STM32 in C language recently. When I use MDK to build the environment, the compilation fails. I am a newbie, so please give me some advice. The first compilation error: ...
In the previous issue, we eliminated letters. This time, we added a fraction lvgl control based on this.
So we need a variable to record the score:
int score=0;//分数初始为0
There is also a label tag:
