Allow ESP32-CAM module to talk to W5500 Ethernet module trough HSPI as SPI (VSPI) pins are used to connect the camera module

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
