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...

Re: ESP32 CAM direct access to image data

But I cannot find the code for dl_matrix3du_alloc anywhere and whilst the calling context makes clear that parameters 2 & 3 are width & height I do not know what parms 1 & 4 are.

Re: Using Timer Interrupt and Reload Timer

I think "timerRestart()" is what you want.
But you need this fix to get it working correctly:

Re: ESP32-Cam and SD Card

Interesting, please test with another ESP32-CAM module, according camera_pins.h GPIO12 and GPIO16 are not used:

Code: Select all

$ grep 37 camera_pins.h 
#define Y8_GPIO_NUM      37
$ grep 16 camera_pins.h 
$ grep 12 camera_pins.h 
$
