080629写了个按键的程序（扫描方式）

刚刚写了个5个按键，扫描方式检测的。烧写进实验板后发现按起来不够灵敏，常常是按N多次才响应一次，高手帮忙看看什么问题。程序包在下面附件里，打算再用中断方式写一个看看。

按键用的是GPF0~GPF4，设置输入，然后检测。有按键放开后响应，UART0输出相应按键信息，同时LED7闪烁相应次数相应。

程序包：

080628我的第一个ARM2410程序（2）

昨天说了一下工程建立、编译链接及得到BIN文件，现在只要烧写到SDRAM里面就可以跑起来看看现象了。烧写前准备工作要做好。

1.先将板的串口线、USB线将PC同实验板连好，一般串口选串口0，具体可能有不同。USB线A字头的连到实验板上，另一端连USBPC机口。当然，板的电源也要。

2.打开调试工具DNW，这个到处都能下到。打开之后，先配置串口点Configuration>Options，出现下面框：

波特率选择115200，com根据你实际用的选。OK之后，点Serial Port>Connect，连接好的话出现下面的框的样子

我这个USB的驱动也装好了，所以后面USB那里有0K字样，如果没装驱动，显示的是+(一个叉）。

假设我的驱动没有装，要用USB下载，就要装上驱动，基本步骤如下：

在线都连好之后，上电实验板。串口出现提示信息，如下图

这时会提示新硬件，弹出安装驱动的框，如果没有，就按ESC，再选择0.

出现安装驱动提示框后，就像平时装驱动一样安装驱动secbulk.inf，安装完就可以用USB下载了，安装成功会提示如下：

然后就可以用USB Port>Transmit下载程序了

下载会出现进度条，下载完之后会出现提示信息，是否运行程序，如下图：

选者Y运行程序，就看见GFIO6出来的LED在闪烁了。

080627成功的烧写到板上，跑了我的第一个程序（1）

今天晚上花了点时间将昨天写好的程序，成功的下到了板上，跑了起来，迈出了实验的第一步。其中用USB下载花了我点时间来装驱动。现在将我跑的第一个程序过程给大家分享下。

首先是用ADS1.2写一个程序，并编译链接。

1.打开ADS1.2

2.File>New

3.建立工程，工程名2410LED，地址存在H:\实验程序\2410LED。前面选择第一项ARM Executable Image。至于下面各项的意义，各位可以到网上下ADS1.2的教程来看看。

4.确定之后

5.点击下图红框，进行调试设置。

点击后，出现下面方框，Targets Setting里，图示Post-Linker选择ARM fromELF。

接着设置Language Setting，将前面两项ARM Assembler和ARM C Compiler在Targets项选者ARM920T，我想大家都明白为什么。

设置ARM Linker，将RO Base设为0x30000000，RW Base设为0x33000000.如下图

转到ARM Linker里面的Layout项，设置如下图：

最后设置ARM fromELF，我们选者输出2进制文件，输出文件名设为2410LED.bin

6.下面向工程中添加文件，大家可以先把我工程包里面的所有C文件和汇编文件拷到上面建的工程文件文件夹里。在工程管理框里邮寄，出现Add Files...，点击出现加文件的框

将工程文件夹里所有的C文件和汇编(S文件）添加到工程，有错误点确定。

加入后，工程管理框如下：

点击上图DebugRel右边的Make图标，编译链接程序。出现一个Error&Warning框，最上面行有显示错误数，警告数等，当错误数为0是通过编译链接，在工程文件家的2410LED_data里的DebugRel中出现2410LED.bin

关于IO口模拟SPI

最近有朋友问到IO口模拟SPI的问题，其实光模拟来说，就时序问题，读取和写入一个字节的时序。

首先选4个IO口，作模拟用，分别模拟CS、SCLK、SI、SO.即是片选、时钟、数据输入、数据输出。

IO口初始化，分别把对应的IO口设置输入输出。CS、SCLK、SO、设置为输出，SI设置为输入。

然后就是时序问题了，一般如下：

//设要写的数据是abyte表示。

CS_1;              //片选高，
SCLK_1;        //时钟高
CS_0;              //片选低，开始工作。
for(i=0;i<8;i++)//循环产生时钟，写入数据。

{
SCLK_0; //时钟低，下降沿
if(0x80&abyte)
SO_1;
else
SO_0;
SCLK_1;
abyte<<=1;
}
SCLK_0;
CS_1;

//设要读的数据是abyte表示。

CS_0;

SCLK_1;

for(i=0;i<8;i++)//读取数据值。
{
SCLK_0;
;;
SCLK_1;
abyte<<=1;
if(in_SI)
abyte++;
}
SCLK_0;
CS_1;

080626Make成第一个实验程序

经过近两天对ADS和2410用户手册的学习，终于搞定了一个可以烧到板上的实验程序。由于板现在不在宿舍，所以还无法搞定。明天看能不能烧到板上跑起来。程序是从网上淘的一个，做了小小修改，以便可以和我的开发板配好。成功与否以及问题，明天同大家讨论。

080618买的ARM9-2410板到了，慢慢学一下。

最近好长时间都没上博了，这段时间好好的理了下工作，最后决定在闲空之余学习一下嵌入式系统，上周在淘宝上买了一块开发板，今天终于一睹了真容。上电试了一下，还不错。上面已经有了个wince的系统，可以跑了，就是触摸屏有点划痕，看起来不爽。由于这两天都有紧要事做，肯能一段时间不能上来了，对于开发板的PP，有空在发。希望在学习过程中，各位高手能指点一二。

AVR(Mega8)的study:13、点亮LCD3510液晶画圆

上一篇讲了画矩形及多边形，以及实块，由于资源问题没能将画圆及圆形实块等加上，这次分开说一下。

效果图：（由于液晶像素点不是正方形，所以看起来圆有点椭，呵呵！）
