Description

An RP2350-based replacement mainboard for Nokia 3310. Rust firmware with browser-based simulator included.

README

What if I could type out messages on my smart phone by using tactile buttons like I used to have on my phone back in high school?

Because the board would need to fit into the chassis of a Nokia 3310 and because there are existing doodads that would be sitting alongside the board anyways, scope has crept to include connecting to these other thingamajigs.

Assuming Rustup

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
  • select nightly
  • load into shell

Setting up web environment

cargo install --locked trunk
cd web
trunk serve

Setting up rp environment

  • Setting up board
    • Install Hardware Test Program
    • Reassemble 3310
    • Manual Test

Ordering from JLCPCB

  1. Download the following files from the latest release:
  2. Upload gerbers.zip
  3. Set PCB Thickness to 1.0mm. This is the thickness of the original board that is being replaced. The case is not designed for boards that are not 1mm thick.
  4. Enable PCB Assembly
  5. Set Assembly Side to Bottom Side
  6. Set PCBA Qty to 2 (or however many you like, but 2 is the minimum)
  7. Click Next to be taken to the next page
  8. Upload bom.csv
  9. Upload cpl.csv
  10. Click Process BOM & CPL

TODO

  • document app API

  • give more control over display flushing, keep track of what needs updating, what needs flushing

    • display can do 90deg rotated addressing

  • allow setting time

  • rp2350 very low power state

  • make all system work live on primary core. give apps dedicated secondary core.

  • 'pre-emption'

  • priveledged, background blocking system calls

  • defmt should be used if possible (instead of log). currently it is used for uart/rtt but for usb i'm using log. is there a way to use usb logging from defmt? will probably require a bit of a bit deep dive

  • placement of some parts is off (rotation for U*)

  • switch off after 5 minutes idle (switching on takes no time)

  • power button: can this be triggered by 'any key'? ie. any keypad press turns the device on. there's enough GPIO to spare that we should have a dedicated GPIO for any key too)

  • power button should turn on device but also function as gpio?
