PtpIpCamera, an ESP32 library for controlling Canon cameras over Wi-Fi
An Arduino library, mostly written by Claude Code, that speaks the PTP/IP protocol used by Canon's EOS Utility to control a camera from an ESP32.

The full story
The maker needed to control a camera over Wi-Fi for another project and found nothing for the ESP32, so released PtpIpCamera, a C++ library that speaks the same wireless protocol as Canon's EOS Utility. It sets aperture, shutter speed and ISO, triggers captures and does exposure bracketing, with no RTOS or dynamic allocation.
It was tested on an ESP32-S3 Feather with a Canon 5D Mark IV. The maker says Claude Code wrote most of the code, as they had no time to implement PTP/IP from scratch.
