Some of the major features of this library are:\n\n1. Use of embedded HAL traits (works with any embedded device that supports the required traits). This means that this driver is platform agnostic.\n2. Library features (only turn on what devices you need to save compiled binary space).\n3. [Examples](./examples) for various RP2040 boards\n\n## Install\n\nTo install this driver in your project add the following line to your `Cargo.toml`'s `dependencies` table:\n\n```toml\nis31fl3743a = \"0.1.0\"\n```\n\n## Examples\n\nSee the [examples](./examples) directory for complete working examples:\n\n- **[qt-py-rp2040](./examples/qt-py-rp2040)** - Adafruit QT Py RP2040 with IS31FL3743A over STEMMA QT\n- **[framework16-keyboard](./examples/framework16-keyboard)** - Framework 16 RGB Keyboard (dual IS31FL3743A controllers)\n\n### Building Examples\n\n```bash\n# Install prerequisites\nrustup target add thumbv6m-none-eabi\ncargo install elf2uf2-rs\n\n# Build an example\ncd examples/framework16-keyboard\ncargo build --release\n\n# Convert to UF2\nelf2uf2-rs target/thumbv6m-none-eabi/release/is31fl3743a-framework16-keyboard firmware.uf2\n```\n\n## Graphics\n\nThis driver contains optional support for the [embedded-graphics](https://docs.rs/embedded-graphics/latest/embedded_graphics/) library.\nEnable the `embedded_graphics` feature to use it.\n\n## References\n\nContains code derived from:\n\n- https://github.com/FrameworkComputer/is31fl3741-rs\n- https://github.com/stillinbeta/is31fl3741\n- https://github.com/gleich/is31fl3731\n\nThe 43A chip is the I2C variant, the 43B chip is the SPI variant of the same chip.\nFor the SPI variant of the device, consider using the `is31fl3741b` crate instead.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fframeworkcomputer%2Fis31fl3743a-rs","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fframeworkcomputer%2Fis31fl3743a-rs","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fframeworkcomputer%2Fis31fl3743a-rs/lists"}
