Re: ESP32-CAM ov2640 exposure control/FREX mode

Added and wired in new "Wait for VSYNC" toggle: https://github.com/Hermann-SW/Raspberry_v1_camera_global_external_shutter/commit/45d6f36b576b75bba79cee3b7c5160a24bdd7851 Gives recreatable results most of the time -- will have to understand why not always. I was victim of "compiler optimizing away st...

Re: ESP32-CAM ov2640 exposure control/FREX mode

Any try to attach an ISR (interrupt service routine) to GPIO25 (VSYNC_GPIO_NUM for ESP32-CAM module) resulted in FCameraWebserver starting, connecting to WLAN and emitting connected messages to Serial, and then immediately rebooting. So I ended up doing poor mans copy of GPIO25 to GPIO16 in order to...

Re: ESP32-CAM ov2640 exposure control/FREX mode

I had the GUI and did know how to do the "shot" captures based on streaming video and not based on still images yesterday: https://www.esp32.com/viewtopic.php?f=19&t=11190&p=45710#p45710 Today I solved the issues left, biggest was to realize that doing "window.stop" to stop MJPEG streaming did show ...

Re: Adding features to Examples->ESP32->Camera->CameraWebServer

Perhaps the offset input can be removed, since I found out how to do what is needed based on streaming video rather than on still image. This is current code for closeButton, that is used to stop streaming: closeButton.onclick = () => { stopStream() hide(viewContainer) } I did comment out the hide c...

Re: Adding features to Examples->ESP32->Camera->CameraWebServer

For adding the new group of "Global external shutter" elements I had to learn how to show/hide based on selected global external shutter mode selected. And I had to learn how to do type="number" inputs because until now there are none. Because I wanted to have a diff of the different index.html vers...

Re: Adding features to Examples->ESP32->Camera->CameraWebServer

Now that I am pretty sure that global external shutter for ESP32-CAM ov2640 sensor is doable, I created a new sub project on github: https://github.com/Hermann-SW/Raspberry_v1_camera_global_external_shutter/tree/master/FCameraWebServer The two new tools get_index_html and put_index_html automate the...

Re: ESP32-CAM ov2640 exposure control/FREX mode

Yesterday I learned how to add new features to ESP32-CAM CameraWebServer example sketch, and provided steps and needed tools: https://www.esp32.com/viewtopic.php?f=19&t=11190&p=45507#p45507 I added a "Flash" toggle https://stamm-wilbrandt.de/en/forum/Flash.menu.png allowing to capture with flash off...

Adding features to Examples->ESP32->Camera->CameraWebServer

Yesterday I did solder a cable to 0.5mm spaced pin10 of ov2640 flat ribbon cable connector on ESP32-CAM module. Via that cable I can control FREX pin B2 (one of 38) of ov2640 image sensor. I want to create global external shutter captures with ov2640 FREX mode: https://www.esp32.com/viewtopic.php?f=...

Re: ESP32-CAM ov2640 exposure control/FREX mode

Last night I did more experiments, and accidentally broke the soldered cable to pin10 connection. It took some more tries to get the cable soldered to this tiny pin again. Unfortunately that solding partly broke my ESP32-CAM board. Flashing CameraWebServer.ino works fine, webserver boots up and serv...
