今天电设的器件清单出来了，整个实验室炸开锅。所以今天就没做什么事，猜题，猜题。

极力想做FFT，不过要用Core的话，XC2S200e做不了1024点FFT，只能用S3的。老大又不肯买，不肯做板。虽然也不一定买得到。明天去买买看。本来还想叫Jingjing买好寄过来的类。。。汗。

数字相位仪做了一个礼拜，碰到两个最花时间的傻问题，一个是程序——CS信号，一个是硬件，输入隔直没加对地电容！

今天：
SPI发送
测量周期
7528程序
会用XCF02配置XC2S200E

决定模拟示波器先缓一下，先做FFT Core，那是杀手锏

今天还算小有成就的

把DDS Core应用的差不多了。实现了多路输出，由单片机输入，给出任意频率正弦波。

接着要测试SPI发送，FFT

明天要完成测频率的任务

还有把信号显示在模拟示波器上的话题，今天开阔了思路。
可以通过内部X轴配合外部Y轴给电压，也可以XY都外部控制。其实XY都外部控制就是VGA了，单色VGA。通过两个DAC控制XY。
不过由于DAC输出的电压只能是正或者只能是负，所以象限的问题有必要考虑。现在想到的解决方法有，再用另外的信号控制Vref的值的正负，可以用MUX。
设都使用8bit DAC，每个象限每个轴256个点，那么整个屏幕就是512x512点。产生一个点的时间算他1us，如果每个点都要扫到，那么整个屏幕需要0.262144秒，3.8Hz。。。不行啊。如果扫完一个点的时间0.1us（DAC10M速度），那么38Hz，还算可以接受吧。况且平时显示的话，是不用满屏的。

时间是越来越紧了

决定明天开始，花四天做一个完整的项目

今天晚上调好了SPI和DDS。没想到这么有效率的，呵呵^_^

原来的SPI有问题是因为连线的抖动，现在换了牢固的线，就一点问题也没有了。

DDS的瓶颈在于DAC，希望明天能用上YL的7528。当然，以后老大肯买更快一点的就更好了。

接下来又空的时候要看各种Core的使用，比如FFT，乘法器，除法器，各种RAM等等。

在研究Xilinx的DDS Core。

现在已经可以出正弦波了，是从chipscope里面看的，不过一个问题是，他的输出都是有符号数输出，而DAC一般要求无符号数输出，这该怎么办呢？？

今天写了几个图形的点阵程序，

一切顺利

^_^

现在我的LCD可以显示图像了

哈哈

不过，过程还是一波三折

首先是不会提取图像的点

虽然小麒把一个图像的二进制文件给了我

but全是0和1

完全不能用

于是，我傻乎乎的自己给这些个0，1加上头标，

整整64×64个点

也就是64×8＝512个字节

眼睛看花掉

但还是咬咬牙，坚持住

或许，本不应该如此“固执”

结果等我把512个字节标完(标到我眼发酸，手发麻)

发现小麒给的数据是从MSB到LSB的

我要求的数据是从LSB到MSB

当场暴晕

@_@

于是打定主意上网找软件

通过楼上LY帮忙

找到一款能把图片的数据读出的软件

拿下来一试

又是一阵晕

这个软件的输出还是不符合要求

输出跟小麒给的数据一样

都是是从MSB到LSB的

无奈

……

一气之下

干脆自己用VC写了个转换程序

哈哈

顺利通过编译

拿来图片一试

效果非常好

^_^

强悍

现在，只要是图片(前提是，黑白的，尺寸<=128×64)

都能显示在我的LCD上了(做好的图片，只要5分钟就能显示)

晚上一时性起

一口气写了几个图片的程序

一个字

爽

果然是自己写的程序

用得舒服

用得放心

^_^

写完图片程序

顺便把触摸屏的算法改进了一下

现在的触摸屏已经反应灵敏，基本无误判了
