## Design
|
|
|
|
### INIT display
|
|
|
|
red = animation, yellow is order of appearance. CPU RAM and DISPLAY values appear after each other
|
|
- states for init display -> states for displaying each part separately, after everything is on screen, state for updating everything
|
|
separate state machine?
|
|
STATES:
|
|
- drop down title
|
|
- display each letter of initializing...
|
|
- display counter values and device info
|
|
- display bluetooth state
|
|
- update everything
