Često postavljana pitanja

Je li CMUcam3 potpuno otvorenog koda i programabilan?

Yes, that’s the point! You can use GCC to compile code and the board can be flashed over any serial port. No need to buy a jtag dongle or any other programming device. This web page provides all of the code, libraries, schematics etc. for the CMUcam3. Click on the Browse Source button at the top of this page to take a look at the source.

Možete li razvijati na Windowsima, Linuxu i Macu?

Da! Koristeći Cygwin pod Windowsima i vaše standardno okruženje za Linux i Mac. Serijski preuzimatelj putem naredbenog retka trebao bi raditi na Macu nakon što pronađete naziv svog serijskog priključka u direktoriju /dev/. Za Mac morate kompajlirati arm-gcc iz izvornog koda. Uskoro ćemo pružiti izvršne datoteke.

Je li firmver CMUcam2 za CMUcam3 potpuno isti?

Ne baš, ali možda u budućnosti. Smatramo da smo implementirali najčešće korištene značajke. Imate izvorni kod pa sami možete dodati bilo koje značajke koje nedostaju.

Trebam li nabaviti CMUcam, CMUcam2 ili CMUcam3?

That depends. The CMUcam and CMUcam2 are designed as fully integrated sensor sub-systems that you use as a black-box. The CMUcam3 can eventually be used in the same way, however you may need to design your own functionality for it. The easiest way to do this is to tailor existing CMUcam3 projects for your application. The CMUcam3’s major advantage is that it is open source and programmable. So you can easily modify or write your own firmware to run on it. As a black-box system, the CMUcam3 supports most but not all of the CMUcam2 functionality. We ported over the features that we saw people using most often. Some of the CMUcam3’s other functionality (like the face detector) requires flashing the CMUcam with different firmware images. That being said, even the CMUcam2 firmware emulation on the CMUcam3 has some extra features like jpeg making it more powerful than the original CMUcam2. The CMUcam3 has a more powerful processor and an SD slot for FLASH storage. The original CMUcam is your best bet if cost is your main concern. See this webpage for a description of the differences between the CMUcam2 and the original CMUcam.
