帮忙看下我的KS0108读字库程序（bg4uvr大哥） [复制链接]

//清屏子程序
void clean_lcd(void)
{
     uchar      i,j=0;

     }
}

void delay_ms(s)
{
unsigned i,j;
for(i=0;i<=s;i++)
{
  for(j=0;j<=1000;j++)
      {

我根据ouravr网站上的一个3310gps读字库程序改的，不知道为什么不行。各位大哥帮忙看下。bg4uvr大哥你应该知道用ks0108显示应该是什么细想给个思路啊

我现在电脑已经没有51的环境，建议你单独调试这个显示程序试一下。显示驱动ok后，再和gps的代码联合调试。

在你的代码中我没有看到字库，实际中使用的时候是必须有6×8点阵的英文字库才可以。

其他的我大体看了一下，应该没大问题。

这是字库
你看清屏的那个函数是不是有问题
！的ascll是33然后减去32等于1
就是去数组的第一个
但是我在调试的时候我把第一个数组里的0x00全部换成了0xff屏幕没点出现，还是和0x00一样，这就怪了，难道写指令和写数据有问题。那个写指令和写程序的程序原来是两个函数，我参考那个3310才合在一起的，现在不显示了。我单步的时候执行到清屏的时候p2口也显示了8个0，但是就是不起作用。也就是没起到清屏作用！在帮我看看啊。我的字符是8*8的

大家看贴帮忙看下程序啊！谢谢，小弟在做毕业设计，谢谢大家了！

晕啊，原来又是毕业设计。唉～

怎么了，好像没必要要骗谁吧。请帮忙看下好吗？原来看过你的那个显示才想起来用ks0108.

目前常用液晶屏成功驱动，所必须的前提：
1、硬件接线正确。并且对比度调整正常。
2、4个基本的函数必须正确。即：写指令、写数据、读状态、读数据(某些串行屏可能用不到读状态和读数据)
3、上电初始化流程必须正确。
4、正常的供电。

如果清屏功能不能正常完成，高级点阵操作是肯定无法完成的，所以你需要按以上4点逐项检查。

调试两天了没发现到底错在哪。单步也执行了，初始化保证绝对没问题。写指令和写函数的程序也应该没问题。应为都是我之前程序截取下来改的。所以不会有问题，所以现在就错在细节方面。我看不到，所以请大家看看的！

'

如果真如你所说，“绝对没有问题”、“不会有问题”，相信你的代码应该已经工作了。我刚才又看了一下，发现据你所说“绝对没有问题”的初始化代码，竟然连扫描启始行都没有设置。兄弟，还是对照屏的说明，仔细检查一下时序吧。我估计不会有很多人真的去详细看你帖的那一大段代码的……

扫描的时候我那个定义坐标函数定义 了。到那个函数里定义扫描，然后在清屏扫描的。这样不可以吗？难道。

你需要仔细看一下你屏幕的说明书。

还可以参考下面这个网页

又见毕业设计。。。而且貌似lz是专门为了毕业设计而上。net的。。。

好的。谢谢，麻烦你了！

如果毕业设计大家都做的很好bg4uvr 我觉得功劳很大的！难道不是吗》

晕……

额。。。如果找到了好工作，记得每月将工资的50%汇给uvr，他的功劳是很大的。

这样的啊。你的想法是不是有点他过分了，毕业设计好像和找到好工作没关系！

lz，我敢跟你打赌，如果你在楼主位说明这是毕业设计，我肯定r不会回你的贴子
http://www.hellocq.net/forum/showthread.php?t=152981

所以r的意思不是说你没骗他，而是你的lz贴骗了他。呵呵。。

我晕，你的意思你很瞧不起毕业生了是吧，毕业生怎么了，毕业设计就该死吗？
毕业生就一定差吗？
