+ +## About The Project + +This project provides a modular and extensible application framework for the +BBC micro:bit. It supports multiple interactive applications with a shared UI +and rendering infrastructure. It uses message-passing channels and safe numeric +arithmetic via bounded, clamped, and wrapped integer types. + +## Features + +* Modular application management with a switcher component. +* Menu, Snake, Badge, and future NFC applications included. +* Real-time rendering to the micro:bit LED matrix. +* Button input driven by asynchronous event channels. +* Renderer abstraction for pixel-level control. +* Channel-based messaging for input and output decoupling. +* Safe integer handling using bounded, clamped, and wrapped types. + +### Built With + +* [Embassy][embassy-url] +* [defmt][defmt-url] + +## Project Structure + +```text +src/ +├── main.rs Entry point of the application. +``` + +## Getting Started + +### Prerequisites + +* Properly installed [Rust toolchain][rust-url]. +* gdb-multiarch Tested version: 15.0.50. +* minicom Tested version: 2.9. +* [cargo-binutils][binutils-url] Tested Version: 0.3.6. +* [probe-rs-tools][probers-url] Tested Version: 0.24. + +The [Rust discovery book][discovery-setup] has a great section on how to setup a +build environment. + +Make sure you have the correct bulid target installed. + +```bash +rustup target add thumbv7em-none-eabihf +``` + +### Build and Flash + +To build and flash the program to your Microbit just run: + +```bash +cargo embed +``` @@ -18,3 +109,18 @@ You may obtain a copy of the License at Unless required by applicable law or agreed to in writing, software distributed under the License is distributed on an "AS IS" BASIS + + + + + +[license-shield]: https://img.shields.io/badge/License-Apache%202.0-%23008400?style=for-the-badge& +[license-url]: https://workshop.cybermages.tech/myrddin/microbadge/src/branch/main/LICENSE.md +[linkedin-shield]: https://img.shields.io/badge/-LinkedIn-black.svg?style=for-the-badge&logo=linkedin&colorB=555 +[linkedin-url]: https://www.linkedin.com/in/jason-smith-cybermages/ +[embassy-url]: https://github.com/embassy-rs/embassy +[defmt-url]: https://github.com/knurling-rs/defmt +[rust-url]: https://www.rust-lang.org/learn/get-started +[binutils-url]: https://github.com/rust-embedded/cargo-binutils +[probers-url]: https://probe.rs/docs/overview/about-probe-rs/ +[discovery-setup]: https://docs.rust-embedded.org/discovery-mb2/03-setup/index.html diff --git a/docs/lsm303agr.pdf b/docs/lsm303agr.pdf new file mode 100644 index 0000000..4729b35 Binary files /dev/null and b/docs/lsm303agr.pdf differ diff --git a/docs/microbit_back.png b/docs/microbit_back.png new file mode 100644 index 0000000..0c87776 Binary files /dev/null and b/docs/microbit_back.png differ diff --git a/docs/microbit_front.png b/docs/microbit_front.png new file mode 100644 index 0000000..6114858 Binary files /dev/null and b/docs/microbit_front.png differ diff --git a/docs/microbit_v2.2.1_nRF52820_schematic.pdf b/docs/microbit_v2.2.1_nRF52820_schematic.pdf new file mode 100644 index 0000000..2f8d6b3 Binary files /dev/null and b/docs/microbit_v2.2.1_nRF52820_schematic.pdf differ diff --git a/docs/nRF52833_PS_v1.7.pdf b/docs/nRF52833_PS_v1.7.pdf new file mode 100644 index 0000000..1945091 Binary files /dev/null and b/docs/nRF52833_PS_v1.7.pdf differ diff --git a/memory.x b/memory.x new file mode 100644 index 0000000..46346e2 --- /dev/null +++ b/memory.x @@ -0,0 +1,5 @@ +MEMORY +{ + FLASH : ORIGIN = 0x00000000, LENGTH = 512K + RAM : ORIGIN = 0x20000000, LENGTH = 128K +} diff --git a/src/main.rs b/src/main.rs index b350918..6428804 100644 --- a/src/main.rs +++ b/src/main.rs @@ -1,18 +1,32 @@ //!
