定义一个延时xms毫秒的延时函数 void delay（unsigned int xms） // xms代表需要延时的毫秒数 { unsigned int x，y;for（x=xms;x》0;x--）for（y=110;y》0;y--）;} 使用：void Delay10us（uchar Ms）{ uchar data i;for（;Ms》0;Ms--）for（i=26;i》0;i--）;} i=［（延时值-1.75）*12/Ms-15］/4
51 单片机的晶振一般为1.2M~12M，其处理速度慢。对于一个12M的晶振来说，一个时钟周期为1us。在STC89C52的软件仿真中，可知其一次执行延迟差不多有10us。循环延迟的时间粗略计算为10us*循环次数。
This allowed to achieve sponge-like structures due to the delay of liquid-liquid de-mixing rate of polymer (Deshmukh and Li, 1998). It was found that the porosities of PVDF membrane were reduced by increasing polymer concentration. Lowering a bath temperature but increasing the thickness of ...
NASA dealt with the problem by continually post- poning necessary work so that it would fall under a subsequent year's budget, with the delay causing the work to double or triple in price. The report admonishes NASA managers, saying that they were aware of the practice of deferring work ...
首先你的函数定义应该是这样吧 define uint unsigned int void delay(uint z){ uint x,y;for(x=z;x--;x>0)for(y=110;y--;y>0);} 在keil uvision软件在12M晶振下执行delay（1）大概延时0.000389秒。1
*/ for(;;) { Pin_frame_Write(1u); // frame ON Beep_VERY_Short_Nx(10); Pin_frame_Write(0u); // frame OFF CyDelay(1000); } } The void Beep_VERY_Short_Nx() does not return until the Buzzer pin is toggled (as expected). I realize my project does not include many of t...
Figure 10 shows a screen capture of a threat actor video posted on Void Arachne’s Telegram channel wherein the malicious actor can be seen using AI face- and voice-cloning technology on a WhatsApp call. Figure 12, on the other hand, shows a malicious voice-altering and face-s...

We have shown the proposed algorithm's effectiveness over the different void sizes on various parameters such as energy consumption, routing length, and end-to-end delay. The GGG algorithm is at least 10 percent more energy-efficient than the other void handling techniques....
void delay_1ms(u16 q) { u16 i,j; for(i=0;i<q;i++) for(j=0;j<120;j++... 原理很简单,就是通过执行没有内容的for循环消耗CPU时间。 为什么keil4用delay函数就要u16 i 单片机编程过程中经常用到延时函数,最常用的莫过于微秒级延时delay_us( )和毫秒级delay_ms( )。1.普通延时法这个...
