新的擷取工具

The new grabbing tool include two parts: the code running in cmucam3 and the software running in PC. You should unzip "cmucam3.rar" and install it on your CMUcam3 first. And then you should download and un-rar "cmucam location.rar". You should be able to execute the software by double clicking on "cmucam location.exe".

在 cmucam3 中執行的程式碼與 cmucam2 專案的程式碼類似。PC 上的軟體以 Microsoft Visual C++ 6.0 為基礎。這個新工具不僅包含「cmucam frame grabber」中的基本功能，還包含一些新功能，例如「save bmp picture to mmc card」、「send bmp picture to pc」。命令細節顯示於下：
