Author here - the reason is pretty underwhelming: These are the parts I had on hand when I decided to start on the project. Using a chip with a builtin Ethernet peripheral would definitely make more sense (though I'd be trading any complexity of configuring the W5100 for the complexity of configuring STs peripheral). The networking code already abstract the actual chip itself into a driver interface (think read/write/ioctl), so porting the code would be pretty straightforward. I'll look into the STM32F407 for the main series. Thanks |

It's not too bad as far as such things go. The documentation on how the DMA system works leaves something to be desired, but it's not bad (and it's a heck of a lot faster than spitting packets over SPI).
