Meeting Notes (2020 08 11)

Meeting Notes

• Issue #70: Refactor config value casting
  • Jesse is hacking away at this.
• Select boxes
  • We don't have control of the styling of the options list.
  • To style the options list we would need to hide the default list, construct a new one in HTML, and handle the actions with Javascript.
  • Tailwind has a note in their select menu source code that they're planning to build low-level libraries to make this easier.
• CI
  • We're checking tests, dialyzer, credo, formatting.
  • GitHub Actions is close to releasing composite steps.
    • #646: Next Steps for Fully Functioning Composite Actions
  • AFK's CI is being prepped for this refactor.
  • What are we doing for CSS/Javascript around CI?
    • Enforcing style: ESLint, prettier
    • Not sure what to use for CSS
    • Prettier will take a lot of configuration because out of the box it doesn't follow the Phoenix Javascript style.
    • How are we testing that the UI does what it's supposed to do?
      • Cypress - Browser automation, similar to Selenium.
      • This might not be worth the effort yet.
      • The LiveView tests are a perfect place to start for now.
• KiCad / PCB
  • Nobody has started working on KiCad yet.
  • Keyboard PCB Designer Guide
  • Matrix design
    • Put a diode in the matrix for every switch to prevent ghosting.
      • There are also ways in software to prevent ghosting. QMK has it. But we should build it out the right way.
    • How does this relate to the TI LM8330 keypad controller?
      • Can't find a diagram in the datasheet showing the diode in the matrix, but that doesn't mean it's not necessary.
      • We should design the matrix to include the diodes where it's supposed to.
      • We poll to get data out of the matrix IC.
      • The IC has a buffer that stores the key events.
      • The way we've been doing matrix scanning so far, we support pressing all of the keys at once; there is no key limit.
