People tell you busyloops are bad but you do busyloops anyway.

Mod edit: Nixed non-relevant image.

Lucas:


while (!i_pic)
{

}



while (!pic_done)
{

}

Thats a big NONO. Busy wait loop. 2 times. Dont. Put a delay in there.In my understanding the delay will allow other tasks o run.

Why do you grab in main loop and send in streamhandler loop? Do the grab in streamhandler too.

btw with ...

Insert a semaphore in "stream_handler" in between

while(true)
{

and
esp_camera_fb_get();

This will delay grabbing the picture until you sync it.

If you dont know semaphores a

while (!newpic) delay(10);
newpic = false;

will do, you can set
newpic = true;
in main loop with ...

Not a pro like u guys, but i have similar issues with two esp32-s modules. WiFi is very bad, video streaming doesent work.

Define your own pins. https://circuits4you.com/2018/12/31/esp ... 2-example/

"Like all peripherals, the pins for the UARTs can be logically mapped to any of the available pins on the ESP32. "

Why would you use softserial on a chip with 2 hardware serial?
Do you understand softwareserial is a cripple going "bang" if there is a small delay in interrupt handling? Do you understand softserial wastes cpu cycles and is unreliable? Avoid that shit like tha plague.

If you insist on using ...

Your 6050 data goes over an angular velocity limit and crashes the esp32? Try lowering the sensivity in the 6050 setup.
I do fly quadcopters with esp32 + mpu6050 and never have this problem, not even on "hard landings".

@HermannSW where did you buy the fast thing?

Testing grayscale 160x120 brightness values. The idea is to detect a line with the esp32 cam and have the vehicle following it.
Here the brightness of the line in-between the 2 grey lines (scanline) is displayed.

Very intresting idea.
Keep us updated pls.

I see i see. You are raspberry - cam expert. I have some serious questions. My raspberry knowledge is = 0.
