sbit P2_4=P2^4;什么意思

sbit P2_4=P2^4;什么意思 sbit RCON=P2^0;这句什么意思 #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 单片机 sbit dula=P2^6 wela=1 dula=1 这三句什么意思 sbit rs = P2^2, sbit p32=p3^2什么意思? #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? 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 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 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; 单片机中sbit P0=P2^0是什么意思 sbit dula=P2^6; sbit wela=P2^7;中,P2^6,P0=0xfe;P0口是什么?初学者纠结.
