sbit dula=P2^6; sbit wela=P2^7;中,P2^6,P0=0xfe;P0口是什么?初学者纠结.

单片机 sbit dula=P2^6 wela=1 dula=1 这三句什么意思 #include sbit dula=P2^6; sbit wela=P2^7;看到很多程序都用dula,wela,它们有中文意思吗? sbit dula=P2^6; sbit wela=P2^7;中,P2^6,P0=0xfe;P0口是什么?初学者纠结. sbit rs = P2^2, ADC0809的参考电压最大是多少?参考电压可以是6V吗?#includesbit c=P1^0;sbit b=P1^1;sbit a=P1^2;sbit st=P3^0;sbit eoc=P3^1;sbit oe=P3^2;sbit clk=P3^3;sbit t=P2^0;sbit f=P2^1;sbit p=P2^2;timer0() interrupt 1 using 1{clk=!clk;TH0=(65536-2) sbit P2_4=P2^4;什么意思 上面的程序在编译时.编译器说：warning c206:'diplay':missing function-prototype erorr c231:'display#includesbit k0=P1^0;sbit k1=P1^1;sbit k2=P1^2;sbit k3=P1^3;sbit d0=P1^4;sbit d1=P1^5;sbit d2=P1^6;sbit d3=P1^7;sbit B0=P3^7;sbit I0=P2^0;s sbit key1 = p1^0; sbit key2 = p1^1; sbit key3 = p1^2; sbit key4 = p1^3; sbit fmq=p2^1;sbit key1 = p1^0;sbit key2 = p1^1;sbit key3 = p1^2;sbit key4 = p1^3;sbit fmq=p2^1; #define GPIO_DIG P0 sbit LSA=P2^2; sbit LSB=P#define GPIO_DIG P0sbit LSA=P2^2;sbit LSB=P2^3;sbit LSC=P2^4;sbit是啥意思啊 求大神 能详细讲讲吗 求解释帝,12864为什么不显字?硬件电路 绝对正确,程序如下：#include#define uchar unsigned char#define uint unsigned int#define LCD_Data P0sbit LCD_RS=P2^4;sbit LCD_RW=P2^5;sbit LCD_E=P2^6;sbit PSB=P2^1;sbit RST=P2^3;uchar code* di 单片机中sbit P0=P2^0是什么意思 sbit RCON=P2^0;这句什么意思 #include <reg51.h>sbit Ir1=P1.0;sbit Ir2=P1.1;sbit Ir3=P1.2;// 红外接收信号sbit beep1=P0.0;sbit beep2=P0.1;//蜂鸣器信号sbit WELA=P2^7; //数码管的位选信号void delay(void) //延时子程序 { unsigned char m,n,s; for(m proteus仿真0-5V的ADC0808单片机电压表,为什么滑动变阻器滑到中间采样值突变为0,采样最大值为2.5V#include<reg52.h>sbit rs=P2^0;sbit rw=P2^1; sbit en=P2^2; //sbit psb=P1^3;sbit START=P3^4;sbit EOC=P3^3;sbit OE=P3^2;sbi sbit clk=P3^0 单片机C语言中 已知：sbit _Speak =P2^3 ; 请问：_Speak = _Speak; 选用一块单片机控制两块ADC0832进行模数转换,如果我选用sbit ADCS =P2^0; sbit ADCLK = P2^1;sbit ADDI = P2^2;sbit ADDO = P2^2;,这样单独定义每一个模数转换通道都能够成功的进行单通道的模数转换,但只要将 sbit p32=p3^2什么意思?
