编程触摸屏 [英] Programming a TouchScreen

问题描述

对于第三年的电子工程项目，我需要编写一个

触摸屏。我将不得不将屏幕，5线电阻式b / b $ b型号连接到ATMEL AVR 90s8535。我不知道从哪里开始。

是否有人知道我将如何设置分辨率，然后将

信号作为串行鼠标命令重新路由？


如果有人有任何经历，请告诉我，alex

Hi,

For a 3rd year electronic engineering project i will need to program a
touch screen. I will have to interface the screen, a 5 wire resistive
model to an ATMEL AVR 90s8535. I have no idea where to begin. Does
anyone know how i will be able to set a resolution, then re-route the
signal as a serial mouse command?

If anyone has any expereince in this please let me know, alex

不是你的教科书和你的班级工作让你知道在哪里开始？b $ b开始？无论如何，你已经发布了错误的新闻组。这个

新闻组处理有关标准C语言的问题。


我不知道正确的新闻组，但是因为你发布了<来自Google网上论坛的
，你没有理由找不到它。

Don''t your textbooks and your class work give you any idea where to
start? In any case, you''ve posted to the wrong newsgroup. This
newsgroup deals with questions about the standard C language.

I don''t know the proper newsgroup offhand, but since you''re posting
from Google Groups, you have no excuse for not being able to find one.

你需要从你拥有的东西开始。

例如，你有硬件，还是你必须建立你自己？

我也不知道AMTEL AVR 90s8535是什么？它是某种微处理器吗？


据推测，你的系统中有一个C编译器和处理器。在
a低级别，处理器通常通过内存映射端口与外围设备通信。


因此，开始的地方是让一些IO设备连接到你的处理器，

和执行IO的C程序 - 例如输入一个数字，递增它，然后输出它。

一旦你知道了C系统正在运行，接下来要做的就是让

触摸屏工作 - 所以你接受输入并产生某种输出。

最后阶段是得到C程序产生你想要的输出

通过高级逻辑指定输入。

You need to begin with what you have.
For instance do you have hardware, or do you have to build it yourself?
I also have no idea what an AMTEL AVR 90s8535 is? Is it some sort of
microprocessor?

Presumably you have a C compiler and processor somewhere in your system. At
a low level, processors usually talk to peripherals via memory-mapped ports.

So the place to start is to get some IO device hooked up to your processor,
and a C program performing IO - eg inputting a number, incrementing it, and
outputting it.
Once you know the C system is working, the next thing to do is to get the
touch screen working - so you accept input and produce some sort of output.
The final stage is to get the C program to produce the output you want for
specified input via high-level logic.

这是一个C问题？


你有设计问题。获取有关硬件，

接口，流程图和时间的信息。


然后编写算法，最后将算法转换为

代码（C或其他）。


新闻：comp.arch.embedded可能对设计细节有所帮助。

How is this a C question ?

You have a design problem. Get information about the hardware, the
interfaces, the flowchart, the timings.

Then write the algorithms, and finally, translate the algorithms into
code (C or whatever).

news:comp.arch.embedded could be helpful for design details.
