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...

Re: ESP32-CAM ov2640 exposure control/FREX mode

Trying to solder something to the uncovered wire was a flop. I read that the size of soldering iron point should be not larger than the size of object to solder to. Despite that I only have 1mm Ø soldering iron and I am not good at soldering, I tried to solder cable to pin10 of flat ribbon connector...

Re: ESP32-CAM ov2640 exposure control/FREX mode

Hmmm, not sure whether it is possible to solder a thin cable to line on the flat ribbon cable. At least there is an area with more space that 0.5mm spacing on the connector, and it is on the up side: https://stamm-wilbrandt.de/en/forum/ov2640.pins.6.part.jpg Raspberry Pi microscope allows to get muc...

Re: ESP32-CAM ov2640 exposure control/FREX mode

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...
