我正在进行一个4位液晶显示器与8051单片机的接口工作,但到目前为止还没有成功。我得到了这个示例代码

我正在用Keil uVision 4编程。
我有一些这样的代码:
sbit X = P3 ^ 3; // X is third bit of P3 register
...
while (1) {
X = !X; // X equals not X ?!
if (X == 0)
printf("0");
else
printf("1");
}
我可以控制`P3^3通用输入引脚,因为在这个引脚上我有一个脉冲红外传感器。它在闪烁时给我1,在休眠时给我0。
当P3^3上拉到1时,
在这里,我提供了使用两个按钮来增加和降低温度的代码。

我正在试着理解这个嵌入的c代码。我认为这意味着它正在将端口位连接到总线中的某个寄存器。如果我错了,请纠正我。我们对端口所做的任何更改都会反映在总线寄存器上。以下是代码的片段。谢谢。

我试图在python中设置XOR函数(如果两个值相等/不同,只需设置0/1 )。在这里,问题是执行没有从内部循环中退出。我试过密码,
我在file.ads中有两个类型和两个数组

我正在尝试创建一个Previewlist,其中我在TFramedVertScrollbar中添加了一个图像和一个删除按钮,在上面添加了以下代码:
var

我正在使用Arduino Uno,试图控制液晶屏幕类型的UC1638 (240x128单色),我想用黑色填充屏幕。搜索internet后,我使用了以下代码(用C编写):
