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
