ESP32 Cam - TimeLapse, Streaming, Prusa Connect

esp32-cam

ESP32 Cam - TimeLapse, Streaming, Prusa Connect ..

Hardware

ESP32-CAM board with OV2640 camera module, there are several hardware versions of the board

• original AI-Thinker board
• different copies, some exact some with notable differences
• S3 version with more PSRAM, faster
  

Flashing HW helper boards

• CH340 chip, USB micro
  

• CH340 chip, USB C, passtru dupont connectors for prototyping
  

Pinout

Instalation

Insert ESP32-CAM into helper board and connect it to PC.

Visual Studio Code with PlatformIO IDE

VSC with PlatformIO

Arduino IDE

Gremlins ate this part - rewrite needed ..

Using Camera

Connect to the DHCP assigned IP and enjoy!

Notable Weblinks

Web server listening port is 8080, changed from default 80 for easier router port-mapping, configurable at start of Web Server code

• {CAM_IP:8080}/login
  enter credentials
• {CAM_IP:8080}/espReset
  force complete ESP32-CAM reset
• {CAM_IP:8080}/sdcard
  reinit SD Card after (re)inserting microSD
• {CAM_IP:8080}/metrics
  output metrics for prometheus/grafana nerds
• {CAM_IP:8080}/scan
  JSON display of neighbour WiFi SSID/Channels
• {CAM_IP:8080}/archive
  browse saved timelapse pictures
• {CAM_IP:8080}/prusa
  force upload of last captured photo to Prusa Connect

Configuration details

• Camera Model
  uncomment only one of the #define that is correct for your camera board
  if you are using ESP32S3-CAM also copy ESP32S3-CAM board definition to PlatformIO dir C:\Users....platformio\platforms\espressif32\boards dir and use 'board = esp32s3cam' in PlatformIO ini
• Config Definitions
  several interesting #defines
  • set #undef HAVE_CAMERA if you don't want to use camera (OV sensor misbehaving or similar)
  • set ESP_CAM_HOSTNAME for your cam board name
  • set CAM_SERIAL if you have several camera boards
  • set FLASH_ENABLED true if you want to use flash LED, currently working only on AI-Thinkers
  • set #undef HAVE_SDCARD if you don't want to use microSD
  • set TIME_LAPSE_MODE true for camera board to start saving interval photos to microSD
• Prusa Connect Setup
  
  • login to Prusa Connect
  • choose registered printer
    • open 'Camera' menu
    • click on 'Add new other camera' and note Token text (copy to clipboard)
    • paste that text in credentials line
      static const char* prusaToken = "paste_here";
      
    • generate fingerprint text with uuidgen command and paste that text in credentials also
      
    • compile and upload the firmware to the cam board, in a minute or so picture should be appearing on Prusa Printer Web

ToDo

• [] add AP/Config mode at the very first start
• [] add GUI config mode for hardcoded #defines
• [] rewrite archive GUI to be much more pwetty
• [] better doc about all hardcoded links
• [] better doc about PC USB drivers

esp32-cam's Issues

prusa connect only reacts on manual refresh

thanks for the great work first!
i got a xiao sense setup. seems everything worked quite fine, i got the prusa connect registered, can adjust and view the webstream, but the camera picture in prusa connect only ever changes when i type 192.169.1.xxx:8080/prusa in my browser and let it push the pic there manually.

refresh rate

is there a chance to make prusa connect refresh the camera picture in shorter intervals?

Not working without connection to PC

Hi,
great project first of all, thanks a lot :-)
I'm using it with a XIAO ESP32 S3 and it works great so far.

But I noticed, that the code is only working when connected to a PC/Notebook, but not when charged only through USB-C.

I think the issue is here:

void setup() {

  Serial.begin( 115200 );
  while( !Serial );   // TODO - rework all Serial outputs to log_info, log_error, log_debug
  ....

If there is no Serial present, it will wait forever. I commented the line while( !Serial ); in my code and now it works.
Just wanting to let you know :-)
