Re: ESP32-CAM ov2640 exposure control/FREX mode

It turned out that Raspberry v1 camera can do global shutter capturing at daylight of fast rotating propeller as well: https://github.com/Hermann-SW/Raspberry_v1_camera_global_external_shutter#daylight https://raw.githubusercontent.com/Hermann-SW/Raspberry_v1_camera_global_external_shutter/master/re...

Re: ESP32-CAM ov2640 exposure control/FREX mode

I just had serious problems in getting any global shutter captures done. It turned out to be good to have serial monitor output in view. The router in vacation house is not good, the time to capture a frame toggles between below 200ms and above 1000ms. And in current state, implementation is fragile...

Re: Two ESP32-CAM synchronously streaming to PI4

- Idea is to connect both ESP32 with a wire and trigger an interrupt to capture synchronously the picture. - Adding fb = esp_camera_fb_get() to the interrupt routine causes a watchdog error. - I don't understand well how the server routine works, so no idea how to get this synchronously to the inte...

Re: ESP32 Remote Control

What is the best way to control ESP32 remotely, without using any third-party software? You are posting your question in ESP32 Arduino forum. For Arduino CameraWebServer example is a good basis of remote control via Wifi as Agree007 stated. You can use the ESP32-CAM module for "ESP32 CAM for FPV an...

Re: esp32 dev board not connecting to wifi

I noticed similar, whenever I flashed [F]CameraWebServer to ESP32-CAM module, or powered on the module, Wifi nearly never connects on first reset (with Serial Monitor started before), and almost always connects on second reset ...

Re: ESP32 CAM for FPV and RC

@HermannSW where did you buy the fast thing? 22$ with free shipping at aliexpress: https://www.aliexpress.com/wholesale?SearchText=tank+robot+Caterpillar It looks fast, especially if doing U-turn at full speed by just changing direction of one motor but keep its speed: https://stamm-wilbrandt.de/en...

Re: ESP32 CAM for FPV and RC

Nice project. I have three of the left type 20$ caterpillar robot platforms, the displayed one in state as received. Plan was to add ESP32-CAM with (big) lipo and try your project for RC and FPV: https://stamm-wilbrandt.de/en/forum/IMG_200719_162011.jpg Recently I received a 7$ toy line following ta...

Re: ESP32-CAM ov2640 exposure control/FREX mode

I did new frame capture, with mostly same settings, but this time with "Wait for next VSYNC" enabled: https://stamm-wilbrandt.de/en/forum/ov2640.global_shutter_done.shots.open_box.4_menu.png This was the captured frame after I clicked "doit" button: https://stamm-wilbrandt.de/en/forum/ov2640.global_...

Re: ESP32-Cam and SD Card

Hi, in case you really cannot use SD card with your two servos and camera, then you might just write to flash instead (SPIFFS). See "Install ESP32 Filesystem Uploader in Arduino IDE" on how you can upload files: https://randomnerdtutorials.com/install-esp32-filesystem-uploader-arduino-ide/ But you c...
