recently i got the WIZ550io board and i’m trying to connect it to fpga.
im trying to write a spi driver in VHDL but i dont know how to start, i couldn’t find a driver example code.
can someone help me or give me a tutorial to begin with?
WIZnet have no W5500 driver for SPI in VHDL. WIZnet just refer to C code example in http://wizwiki.net/wiki/doku.php?id=products:w5500:driver.
Anyway, W5500 SPI hardware spec should comply with the standard.
Also W5500 SPI just supports MODE0 & MODE3.
SPI Control & data frame refer to W5500 datasheet.
