num[]={0x80,0xc0,0xe0,0xf0,0xf8,0xfc,0xfe,0xff,0x7f,0x3f,0x1f,0x0f,0x07,0x03,0x01,
51单片机P0口接8各不同阻值的电阻,输出16分段的正弦波
num[]={0x80,0xc0,0xe0,0xf0,0xf8,0xfc,0xfe,0xff,0x7f,0x3f,0x1f,0x0f,0x07,0x03,0x01,0x00};
.
P0 =num[time];
time++;
if(time == 16)
{
time = 0;
}
num[]是一维数组,
int num[]={0x80,0xc0,0xe0,0xf0,0xf8,0xfc,0xfe,0xff,0x7f,0x3f,0x1f,0x0f,0x07,0x03,0x01,0x00};
把0x80,0xc0,0xe0,0xf0,0xf8,0xfc,0xfe,0xff,0x7f,0x3f,0x1f,0x0f,0x07,0x03,0x01,0x00的16个整数值给num一维整数数组初始化赋值
再问： 我知道是数组，我想问的是为什么填那16个进制数
再答： 你喜欢填十进制数也行中,十六进制方便容易输入吧,看各人爱好!
单片机C语言中0xfc,0xf9,0xf3,0xe7,0xcf,0x9f,0x3f,0x7f,0xff,有什么作用? SYNR =0xc0 | 0x07 ；REFDV=0x80 | 0x01 中0xc0 | 0x07和0x80 | P1=0x7F; for(i=0;i>=1; P1 |=0x80; } C51中,有这样一条指令如下：SID=P1^1; i_data=0xf8; SID=(bit)(i_data&=0x80 chainloader (0xff)是什么意思 temp=~((temp>>4)|0xF0) C语言 逻辑运算if((a&0xf0)!=0xf0) if((a&&0xf0)!=0xf0) 分别什么意思解释一下谢谢 P1!=0xfe 什么意思? 343-1ex21-0xe0模块上 fast fdx temp&0x80)==0x80什么意思 if((temp&0x80)==0x80) #define SWP_TYPE(x) (((x).val >> 1) & 0x3f)
