Thank you for the suggestion, I'll look into that!

I want to point the ESP-EYE directly at the mouth, then do detection of a smile or a frown. Any idea how this could be approached?

Note that the camera will only see the mouth, not the entire face.

In a test, I was successfully able to use SPI with pins: #define GPIO_MOSI 2 #define GPIO_MISO 12 #define GPIO_SCLK 14 #define GPIO_CS 15 However, I cannot run the camera in parallel with my own SPI communication. The problem are not the pins. Pins 2, 12, 14, and 15 are not used by the camera. The p...

When programming the ESP32-CAM with an FTDI, I proceed as follows: Connect IO0 to GND. Reset the ESP32-CAM. (by cutting power) Run: python2 $(which idf.py) -p /dev/ttyUSB0 flash --baud 2000000 Afterwards, to monitor output: Remove IO0 from GND. Reset the ESP32-CAM. (as above) Run: python2 $(which id...

What's the field of view (FOV) of the OV2640 camera on the ESP-EYE?

Also helpful would be focal length and sensor size, the parameters from which the FOV can be calculated.

From an ESP-EYE, I want to: Stream from the camera to the web server (as in the example application camera_web_server ). Face detection is not required. Connect to a Websocket server running on another computer to send messages. Can this be done at the same time? Concerning Websockets, I found that ...

Well I guess it isn't. So I will use a level shifter (unless I'm missing something and there is a simpler way to connect to a 5V Arduino).

What options are there?

I assume the easiest way is to use SPI with a level shifter (unless the ESP-EYE's SPI port is 5V tolerant).
