Re: ESP32 Board with solar, battery, LoRaWAN and GPS

No need for a battery if you are good with hand generator -- but you are not allowed to stop ;-)

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=...
