Template for a REST API non-blocking WebServer app for Pico RP2040 and WizNet Ethernet modules (W5100, W5500)
This template features the follwing, with working sample code:
- Ethernet driver for WizNet modules (tested W5100/W5500)
- Non-blocking WebServer
- REST API handler
- JSON serialiser
Here's a basic pin mapping for connecting the RP2040 to the W5100/W5500 module:
| W5500 Pin | RP2040 Pin | Description |
|---|---|---|
| VCC | 3.3V | Power Supply |
| GND | GND | Ground |
| SCK | GPIO18 | SPI Clock (SCK) |
| MISO | GPIO16 | SPI Master In Slave Out (MISO) |
| MOSI | GPIO19 | SPI Master Out Slave In (MOSI) |
| CS | GPIO17 | Chip Select (CS) |
| RESET | GPIO20 | Reset |
| INT | Not Connected | Interrupt (optional) |
