Gyakran ismételt kérdések

A CMUcam3 teljesen nyílt forráskódú és programozható?

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.

Lehet fejleszteni Windowson, Linuxon és Macen?

Igen! Windows alatt a Cygwin használatával, Linuxon és Macen pedig a szabványos környezetével. A soros parancssori letöltőnek működnie kell a Macen, ha megtalálja a soros portja nevét a /dev/ könyvtárban. A Machez az arm-gcc-t forrásból kell fordítania. Hamarosan biztosítunk végrehajtható fájlokat.

A CMUcam2 firmware a CMUcam3-hoz pontosan ugyanaz?

Nem egészen, de talán a jövőben. Úgy gondoljuk, hogy a leggyakrabban használt funkciókat megvalósítottuk. A forrás az Öné, így bármely hiányzó funkciót saját maga hozzáadhat.

CMUcam-et, CMUcam2-t vagy CMUcam3-at vegyek?

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.
