To prove the Canon EDSDK free download is worth your time, here’s a minimalist C++ console app that connects to a camera and captures one image.
#include "EDSDK.h" #include <iostream>
int main() cameraList == nullptr) std::cerr << "No camera list\n"; EdsTerminateSDK(); return -1; EdsInt32 count = 0; EdsGetChildCount(cameraList, &count); if (count == 0) std::cerr << "No camera connected\n"; EdsRelease(cameraList); EdsTerminateSDK(); return -1; EdsCameraRef camera = nullptr; EdsGetChildAtIndex(cameraList, 0, &camera); // Take a picture err = EdsSendCommand(camera, kEdsCameraCommand_TakePicture, 0); if (err == EDS_ERR_OK) std::cout << "Picture taken!\n"; else std::cerr << "Failed to take picture\n"; // Cleanup EdsRelease(camera); EdsRelease(cameraList); EdsTerminateSDK(); return 0;
Compile, link, run with a supported camera attached. That’s the power of the free EDSDK.
Even the most careful developers run into roadblocks. Here are solutions to frequent problems when attempting a Canon EDSDK free download and subsequent installation.
