Hey, #programming #electronics #arduino #microcontroller folks. Say I have a device like a joystick which generates its own data and clock signals, and I want a Pi Pico 2 to capture inputs from it.

What should the flow of that program look like? Do I just capture 2x the length of a full packet, find the single whole packet in it, read that and move on? How would you go about detecting and reading every individual packet?

Boosts and all comments welcome.

Screenshot from logic analyser program PulseView, showing a data and clock signal from an old joystick. The clock signal is going up and down in regular blocks of ten, in sets of four; the data signal is repeating in a pattern on top of that.

System Administration

Week 9, Writing System Tools

This week we're going on a side-quest to discover solid #programming best practices that apply across simple scripting, prototyping, growing your tools, and owning a software product. We don't have videos for this topic, but the slides below include a lot of hopefully useful links ranging from coding style to ticket management and commit messages.

A flow-chart like illustration of the evolution of sysadmin tools from shell aliases and scripts to /usr/local/bin tools to system-wide installation to full-fledged software product with an API. As complexity increases, the number of users increases, but the number of assumption we can make about the environment in which the code runs decreases.
