Ethernet Library for ESP32-CAM using HSPI interface and W5500 module
Allow ESP32-CAM module to talk to W5500 Ethernet module trough HSPI as SPI (VSPI) pins are used to connect the camera module
How to use
Check out examples/ESP32EthCamera.ino as it initializes the W5500, listens on port 80 and sends the JPG stream from the camera directly to the web client
Assembled from
- Arduino Ethernet library v2.0.0
- ESP32-CAM example “CameraWebServer”
This is mostly copy/paste and search/replace, there’s nothing “smart” done here. Ethernet library is search/replace to not use SPI but SPI2 and I renamed W5100 to W5500 (mostly so I’m sure I’m using the right one) and I initialized SPI2 as HSPI. The example .INO file is adapted to use this library and send jpeg stream.
Licence
- My work – public domain / unlicence
- Their work – Whatever is copied from those two is whatever their licence is
Hardware
- ESP32-CAM AI-Thinker module (changing the CAMERA PINS should work with any other esp32-cam, but I have not tested)
- W5500 Ethernet module (I removed the pieces for 5100 and 5200 from the library as I don’t need them)
Connection
- GPI0 to GND and then reset to program
- GPI1 and GPI3 to your TX, RX uart for programming
- You need to disable power to the W5500 in order to program ESP32 (no idea why)
- ESP32-CAM → W5500
- GPIO12 → MISO
- GPIO13 → MOSI
- GPIO14 → SCLK
- GPIO2 → SCS
- GND → GND
I am powering both from same externam 5V source
Since GPIO2 is used for chip select this should not affect SD card operations as SD card is also using HSPI spi interface

Ethernet Library for Arduino
With the Arduino Ethernet Shield, this library allows an Arduino board to connect to the internet.

Hi, do you know the “Watermeter” by “jomjol”?
It’s a great AI on the Edge visual Meter-recognition. Check this out, with your approach it could be improved it. support?
https://github.com/jomjol/AI-on-the-edge-device/discussions/607
It’s an interesting project.
I’ll consider it but not sure when I will do that.
Thanks for your idea.
