Question about LED flashing (newbie question) [Copy link]

I want LED lights 0 and 2 to be always on, and LED light 1 to flash. Please help me

The most direct and simple way is to put the two statements LED0 and LED2 before the while(1) main loop. In this way, in the main loop, only LED1 will turn on and off, while LED0 and LED2 will always be on.

Your current method can be achieved, but it is a bit slow

There is nothing wrong with this program, and it is recommended to do this. You just need to know that the program is a continuous loop!

There is nothing wrong with the logic of the program, it's just that the delay time is a bit crude. The error is because there is an extra semicolon after your delay function, just remove it.

There is an extra ";" after your delay function.
