(原創) 如何解決DE2範例DE2_CCD_detect左右相反的問題? (IC Design) (DE2) (Quartus II)

Abstract
DE2_CCD_detect是友晶科技為DE2和其130萬像素CMOS所寫的motion detection範例,有motion之處會在輸出的VGA顯示紅色,但官方的範例會造成左右相反,本文提出解決的方式。

Introduction
版權聲明:本文根據友晶科技光碟所附的範例程式加以修改,原範例版權歸友晶科技所有。
使用環境:Quartus II 7.2 SP1 + DE2(Cyclone II EP2C35F627C6) + TRDB_DC2

在友晶科技的範例程式光碟中,有兩個有趣的例子,一個是DE2_CCD,展示了130萬像素CMOS基本free run與capture的功能,一個是DE2_CCD_detect,能做real time的motion detection,成果展示可在http://www.terasic.com.tw/cgi-bin/page/archive.pl?Language=Taiwan&CategoryNo=38&No=62 觀賞。

DE2_CCD結果正常,DE2_CCD_detect雖然能正確的做出motion detection,但可惜左右相反,經過一番研究,本文提出想種解決方法。

Method 1
這是我寫email問友晶科技(supprt@terasic.com)後,所回覆的官方解法,最簡單也最直接,直接修改I2C_CCD_Config.v。

原來是16'hF101,改成16'F103後就可以左右正常。

Method 2
在DE2_CCD中,影像其實原本也是左右相反的,但他透過了Mirror_Col將左右影像再做一次mirror變正常,所以我們試著也將DE2_CCD_detect模仿DE2_CCD所使用的技巧。

Step 1:
將DE2_CCD中的Mirror_Col.v與Stack_RAM.v複製到DE2_CCD_detect目錄下。

Step 2:
修改DE2_CCD_detect.v如下
