Arduino Test Bench for Canon EF-Eos Lenses
by CANONComplete technical documentation for building and operating an Arduino-based test bench designed to evaluate Canon EF-Eos lenses. This workshop guide covers the full hardware architecture using Arduino Mega with LCD shield, including power supply circuits with voltage protection stages and SPI communication protocol implementation. The manual details the complete software structure and 21 distinct test functions for systematic lens evaluation: diaphragm control sequences, autofocus motor operation, image stabilization command testing, and focus distance measurement routines. Two hardware platform configurations are fully documented with electrical schematics, wiring diagrams, and complete Arduino sketch source code listings for both versions. Essential reference for anyone building custom test automation or diagnostic systems for Canon EF-Eos lens compatibility and performance verification.
Documentation must be downloaded on a computer (PC, Mac, or Linux).
Do not use a smartphone or tablet to download documentation; they generally lack sufficient memory capacity to handle large files, and few users know how to locate the download folder on these devices.
Once downloaded, you can use it right away and even print the pages you need, or use your smartphone in photo mode to translate into the language of your choice: Google Translate
