Teensy-Only Wiznet Ethernet Library

Project description

Improved Performance Ethernet Library Wiznet chips W5100, W5200 and W5500 are automatically detected. Efficient block mode of W5200 & W5500 are used for data and multi-byte register access. Wiznet socket registers are cached, which greatly reduces SPI communication overhead, at the cost of a small increase in RAM usage. TCP connections and UDP packets accessed in small chunks typically see a substantial performance boost. Adafruit's Ethernet.init(CSPIN) extension is supported, to allow use of different pins for the chip select signal. Optimized direct register I/O is used for most Arduino…
