Software Development Kit
The Canon EOS Digital Camera Software Development Kit (EDSDK) and the Camera Control API (CCAPI) are available on select Canon cameras1 and enables developers to integrate select Canon cameras directly into their software application solutions, giving them access to remote control and communication functionality of the camera. The EDSDK supports USB communication on Windows, Macintosh, and Linux operating systems, while the CCAPI uses Wi-Fi (Ethernet on select cameras) and can be used with almost any OS.
The EDSDK and CCAPI (along with other SDKs and APIs) are provided free of charge and more information can be found at https://www.usa.canon.com/support/sdk.
