# Hardware
|
|
- Display Resolution: 192x160
|
|
- potentially just upscaled from 96x80
|
|
- at 3x scaling that's 576x480, 32px pillarboxes if 640x480
|
|
- 384x320
|
|
- how small can the screen physically be?
|
|
- android guidelines say 48dp @ 160dpi or 0.3"
|
|
- android guidelines also say 48dp is about 9mm so who the fuck knows anymore
|
|
- apple says 44pt ~~or 44/72" or 0.61"~~
|
|
- 44pt is 44px, 88px, 132px depending on device
|
|
- 132px on iPhone X @ 448(?)dpi so ~ 0.294"
|
|
- 192x160 is 1.2"x1"
|
|
- 640x480 is 4"x5" for a 6.4" diagonal
|
|
- 28.8" x 24" needed to meet android accessibility guidelines jfc
|
|
- tl;dr: Apple and Google seem to want about 0.3"per target
|
|
- NDS screen size is 106.666 dpi
|
|
- poketch would be 1.8x1.5"
|
|
- **640x480 would be 2x1.5" or 2.5" diagonal**
|
|
- https://www.adafruit.com/product/2478 should do the trick
|
|
- 320x240 2.4"
|
|
- we use 288x240 (1.5x)
|
|
|
|
- 2 Bit grayscale
|
|
- Touch screen
|
|
- 5:4 aspect ratio
|
|
- 1/2 physical buttons
|
|
# etc
|
|
- will need a font
|
|
- sprite based?
|
|
- ttf based?
|

|
|
# stretch goals
|
|
- use wifi/ble
|
|
- config applet
|
|
- also would handle right vs left handed
|
|
- mqtt/ntfy.sh
|
|
- display notifications using margins?
|
|
- android notifications sync
|
|
- requires adding to gadgetbridge long term
|
|
- pedometer
|
|
- needs extra hardware
