I was not sure whether A2 and B2 were exposed to connector pins, could be, could be not. I started to verify G5, G6, E5 and G4 by looking up where the pin should be based on black see-through photo, and then measuring near 0Ω on ohmmeter. It turned out not to be difficult to just select one of the 2...

In order to verify visually determined sensor pin to connector pin connections it is necessary to use ohmmeter. The connector pins are so small that it is really difficult to hit them. Luckily I had a spare 24-line cable mount. I fixated that to desk with a one-hnded clamp. Then I brought Raspberry ...

This are the 16 pins from previous P.S marked in datasheet diagram: https://stamm-wilbrandt.de/en/forum/ov2640.pins.work.jpg I did remove a metallic plate on the other side of the connector. Grey glue parts remained. Again I did an IR light see-through image, this time with 48-led IR light directly ...

Unlike ov5647 sensor that allows to enter FREX mode either via I2C command (which I did for my global external shutter work) or via pin signalling, ov2640 sensor only allows to enter FREX mode via pin signalling. The interesting pins for entering FREX mode are A2 (EXPST_B) and B2 (FREX), from ov2640...

CameraWebServer.ino does not support ov7670 as the error message you get states. Only ov2640 (2MP) and ov3660 (2MP) are supported (only for those webpages are defined in "~/.arduino15/packages/esp32/hardware/esp32/1.0.2/libraries/ESP32/examples/Camera/CameraWebServer/camera_index.h"). P.S: Better ex...

I recently built a global external shutter for (ov5647 sensor) Raspberry v1 camera: https://github.com/Hermann-SW/Raspberry_v1_camera_global_external_shutter Since ov2640 sensor is a predecessor of ov5647 and has FREX mode as well (that enables starting accumulation of all sensor lines at the same t...

I want one ESP-EYE to check. how to apply one?

Has anybody an answer to this?

I searched for ESP-EYE on espressif.com and got a single hit to an "overview" page, but that linkis broken ...

It works! This is video of wireless USB keyboard connected to native Arduino Due port, its key presses being forwarded to ESP32 MicroPython REPL with Oled display. The video shows all, but the Oled display cannot be seen detailed enough. The sketch does use Arduino USBHost library KeyboardController...
