51单片机C语言实现：8个LED从两边向中间依次点亮（附代码及延时调速方法）

以下是实现单片机控制8个LED从两边向中间逐渐点亮的示例代码，使用51单片机和C语言编程： ```c #include <REG51.H> sbit L1 = P2^0; sbit L2 = P2^1; sbit L3 = P2^2; sbit L4 = P2^3; sbit L5 = P2^4; sbit L6 = P2^5; sbit L7 = P2^6; sbit L8 = P2^7; void delay(unsigned int t) { unsigned int i, j; for(i=0; i<t; i++) for(j=0; j<120; j++); } void main() { L1 = 0; L2 = 0; L3 = 0; L4 = 0; L5 = 0; L6 = 0; L7 = 0; L8 = 0; while(1) { L1 = 1; delay(50); L2 = 1; delay(50); L3 = 1; delay(50); L4 = 1; delay(50); L5 = 1; delay(50); L6 = 1; delay(50); L7 = 1; delay(50); L8 = 1; delay(50); L1 = 0; delay(50); L2 = 0; delay(50); L3 = 0; delay(50); L4 = 0; delay(50); L5 = 0; delay(50); L6 = 0; delay(50); L7 = 0; delay(50); L8 = 0; delay(50); } } ``` 这段代码通过让8个LED依次从两边向中间点亮，每次灯的点亮持续时间为50毫秒。可以根据实际需求调整延时时间来控制LED灯的点亮速度。 ######[AI写代码神器 | 793点数解答 | 2024-07-04 21:37:28]
