I sent an Ethernet packet

I'm sick of complex blogging solutions, so markdown files in a git repo it is - francisrstokes/githublog

Ethernet is actually a whole family of technologies and standards (many of which are now obsolete) that encompasses the hardware involved at the physical level, various signalling formats that encode and transmit bits, the strategies for dealing with bus collisions, and the layout of frames, which contain and protect the data being sent from one place to another. In the middle is some speedy magical silicon which buffers, conditions, and samples those channels at a high rate, compresses the bitstreams, and pushes them through the USB, ready to be analysed by software. In this instance, I wanted to take the SPI capture CSV export coming the Saleae's Logic2 software, parse the bytes, and present a list of register writes and reads, with proper names, formatting, etc.
