Re: Two ESP32-CAM synchronously streaming to PI4

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

Re: Two ESP32-CAM synchronously streaming to PI4

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 640x480 jpg i get ...

Re: Two ESP32-CAM synchronously streaming to PI4

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 appropriate timing. //------...

Re: ESP32 Manufacturing QC issues

Not a pro like u guys, but i have similar issues with two esp32-s modules. WiFi is very bad, video streaming doesent work. https://imgur.com/a/g62cXWu IF i press my finger on the pcb antenna in the red circle it suddenly works. I guess an impedance matching problem? Are some of the rf components bad...

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. "

Re: ESP32-CAM and EspSoftwareSerial with CamerWebServer

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 softser...

Re: ESP32 resets on mechanical shock

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".

Re: ESP32 CAM for FPV and RC

@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. Clipboard01.jpg What is a clever way of ca...

Re: Pinchange interrupt during eeprom write -> crash.

I see i see. You are raspberry - cam expert. I have some serious questions. My raspberry knowledge is = 0. Sending broadcast video frames from esp32cam to raspberry? How-to? Which aliexpress raspberry as video RX to buy? Which mini raspberry with cam as video TX to buy? This stuff any good? https://...
