Switching Between Two ESP-CAM Boards on a Single TFT Display via SPI
Hey guys i’m working on a project where I need to connect two ESP-CAM dev boards to a single TFT display via the SPI bus. My goal is to display the video feed from either camera on the TFT display, selectable via a button press. I'm aware that this can be achieved using ESP-NOW with three ESP32 boards (two cameras and one for the display), but I'm looking to maintain the high frame rate achievable through direct SPI bus connection. Is it possible to share the SPI bus between the two ESP-CAM boards and switch between them seamlessly? If so, what would be the best approach to accomplish this?
