I looked into many (preliminary) ov2640 datasheets on the web, and all show this same SVGA Frame Timing diagram, which is inconsistent: https://stamm-wilbrandt.de/en/forum/ov2640.svga.timing.png Diagram says that t_LINE is 1190 t_p, and summing up all components gives 866416 t_p. But 672×t_LINE is 7...

I think I made a good capture, and a good observation as well. This was the global shutter setup, 2 shots, 50µs flashes, 950µs apart. And offset 170ms: ...,"flash":0,"ges":2,"ges_gpio":0,"ges_repeat":2,"ges_vsync":0,"ges_offset":170,"ges_on":50,"ges_off":950} The observation I made is, that when pre...

The Serial prints are useful with Serial monitor timestamps: 16:16:08.410 -> Camera capture send before 16:16:08.444 -> Camera capture send after 16:16:08.444 -> JPG: 22291B 174ms 16:16:09.973 -> Camera capture send before 16:16:10.007 -> Camera capture send after 16:16:10.007 -> JPG: 21786B 127ms P...

CameraWebServer app_httpd.cpp does send the whole framebuffer. Add serial monitor output like below and enable output of timestamps in console. Then you can measure what speed that method of framebuffer transfer does: Serial.println("Camera capture send before"); res = httpd_resp_send(req, (const ch...

I don't know where to find official ESP32-CAM SD card pinout. I found this: https://raw.githubusercontent.com/v12345vtm/timelapse-ESP32-CAM/master/README.md ESP32-CAM board uses the SD card to the following pins: SD Card | ESP32 |esp32-cam D2 - - D3 SS gpio13 CMD MOSI gpio15 VSS GND gnd VDD 3.3V 3.3...

Now that even daylight global shutter captures are possible, I wanted to add "frequency" feature allowing to specify frequency [Hz] and On [µs] and get permanent flashes of the specified length with the given frequency. Just having started I thought that this can be done with "shots" option without ...

Current state of ov2640 global shutter experiments is, that soldering cable to ESP32-CAM flat ribbon cable connector was not necessary. In addition, ov2640 sensor allows for: some kind of "implicit" global shutter mode global shutter capturing at daylight without external shutter mixed mode global+r...

Sending broadcast video frames from esp32cam to raspberry? How-to? Take Pi ZeroW or any other Pi with Wireless and transfer via Wifi. Raspberry PIs run Raspbian, a Linux variant derived from Debian. Only the Zero[W] is (1GHz) single core, all other PIs are quad core (1.2GHz or 1.4GHz). Which aliexp...

I need a sub-500g drone because of local regulations. My old F330 frame is 700g. Local regulations exist in Germany too; I had four Eachine E52 drones, lost one in a high tree. Those drones wheigh less than 100g, and in Germany drones <250g don't even need a fireproof ID label. Since the E52 does h...

👍 You reference a previous non-external RC video in your github page as well. I added github repo link to the new youtube video as comment: https://github.com/PepeTheFroggie/EspCopter32 Nice diagram. Do you plan to replace the ESP32 used with ESP32-CAM that you used in your "ESP32 CAM for FPV and RC...
