STM8S code examples

This is a collection of code snippets for various features on the STM8S family microcontrollers (specifically the STM8S003F3). These are written against the STM8S/A SPL headers and compiled using SDCC.

Some of this controller's functions aren't particularly intuitive to program, so I'm dumping samples for future reference here. These are based on the STM8S documentation:

Run at 16MHz

tech and ethics reading collection

Tech and ethics reading collection

A list of books, essays, papers, blog posts, tweets, etc. on tech and ethics that I have either read and found useful or plan to read because I think they might be useful. I’m not especially interested in ethics that doesn’t take power or structure into account, so most of the standard texts one would read in a course on ethics aren’t represented on my list.

(My) starting point

Not strictly about either ethics or tech, but Claire Dederer’s What Do We Do With the Art of Monstrous Men? verbalizes something that is wound up in how I think about ethics, and what I hear when people talk about ethics:

This, I think, is what happens to so many of us when we consider the work of the monster geniuses—we tell ourselves we’re having ethical thoughts when really what we’re having is moral feelings.

hacking the kindle paperwhite

TODO - hack the kindle paperwhite

focus on the gen 2 / DP75SDI

compile kernel + initramfs with openwrt:

  • because it cross-compiles easily
  • has a reasonably simple user-space
  • device-tree?
