Meeting Notes

Requires Nerves.Runtime.validate_firmware() to be run from IEx on the target if upgrading a pre-2.0.0 system via SSH.
Not an issue if burning an SD card.

Wireframes
Animations
- First iteration can launch as enable/disable sliders.
- Users should be able to customize and store animation configurations in this screen.
- Users should be able to duplicate animations and set different configurations. They could create two hue wave animations that animate in different directions when they start playing.
- Users should be able to choose the animation that plays when Xebow first starts (the startup animation).
Key bindings
- AFK scancodes
- First iteration can launch with a static list of AFK codes that the user can select from.
- Need a way to group functionality or the list could become difficult to navigate.
- Could also implement a search function.
- What happens if a user unmaps all of their keys?
  - They need to drag and drop the key codes back in with the mouse.
  - They may not be able to access a web browser at this point.
  - Should we have a default profile that acts like a standard keyboard that the user can fall back to in case they end up in this situation?
    - Have a key combination they can hold at device startup that sets this default profile as the active one.
Console
- Nerves Hub is implementing a web-based CLI. We may be able to take a look at this code to figure out how to do it.
- There is a potential security vulnerability with exposing a web-based console if it does not require authentication.
Add the ability to change the USB Ethernet endpoint mode (Auto/RNDIS/NCM).

A 14"x5.25" PCB is very reasonably priced from JLCPCB.
We could make a prototype PCB and avoid populating all of the components (i.e. keys) to save cost while iterating on the software.
TI makes the LM8330, a keypad controller that supports a full 104 key keyboard and has builtin debouncing.
We need to brush up on the article on how to build a mechanical keyboard PCB in KiCad.
