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: ...
I would like to ask you all, I have a question. I want to implement a function, the PC sends a hexadecimal number to the MCU, and then the MCU writes the value to the P1 port to control the LED connec...
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:
