Re: Esp32 CAM sending image buffer over TCP

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...

Re: Esp32 CAM sending image buffer over TCP

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...

Re: ESP32-Cam and SD Card

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...

Re: ESP32-CAM ov2640 exposure control/FREX mode

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 ...

Re: ESP32-CAM ov2640 exposure control/FREX mode

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...

Re: Pinchange interrupt during eeprom write -> crash.

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...

Re: Pinchange interrupt during eeprom write -> crash.

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...

Re: Pinchange interrupt during eeprom write -> crash.

👍 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...

Re: ESP32-CAM ov2640 exposure control/FREX mode

I did use "shots" tool again with these settings: ...,"ges":2,"ges_gpio":0,"ges_repeat":3,"ges_vsync":0,"ges_offset":190,"ges_on":100,"ges_off":1000} This time I had the exact same scene to capture (only the hand moved slightly between the two captured frames). Depending on when I did press "doit" b...

Re: ESP32-CAM ov2640 exposure control/FREX mode

Just realized that the ESP32-CAM module I most often worked with did have some heat issue with the flash and got black: https://stamm-wilbrandt.de/en/forum/IMG_130719_171925.part.jpg Luckily it was recoverable with a simple knife: https://stamm-wilbrandt.de/en/forum/IMG_130719_174414.part.jpg I am p...
