Create RMK firmware project

In this section, you'll create your own RMK firmware project using RMK project template and cargo-generate.

1. Create from template

RMK provides a project template, making it much easier to create your own firmware using your favorite microcontroller. cargo-generate is required to use the template, you can install it using the following command(if you've installed cargo-generate, just skip this):

cargo install cargo-generate

Then you can create your RMK firmware project with a single command:

cargo generate --git https://github.com/HaoboGu/rmk-template

This command would ask you to fill some basic info of your project, it requires a little bit deeper understanding of your chosen hardware. If you don't know what to fill, check this section in overview first. The following is an example. In the example, a stm32 microcontroller stm32h7b0vb is used, the corresponding target is thumbv7em-none-eabihf:

$ cargo generate --git https://github.com/HaoboGu/rmk-template
🤷   Project Name: rmk-demo
🔧   Destination: /Users/haobogu/Projects/keyboard/rmk-demo ...
🔧   project-name: rmk-demo ...
🔧   Generating template ...
✔ 🤷   Choose your microcontroller family · stm32
✔ 🤷   Choose your microcontroller's target · thumbv7em-none-eabihf
🤷   Enter your MCU model(Embassy feature name): stm32h7b0vb
️️👉👉👉 For the following steps, search 'TODO' in generated project
🔧   Moving generated files into: `/Users/haobogu/Projects/keyboard/rmk-demo`...
🔧   Initializing a fresh Git repository
✨   Done! New project created /Users/haobogu/Projects/keyboard/rmk-demo

A RMK firmware project will be automatically created after you fill out all required fields. Use code <your-project-name> to open the project in VSCode. If you're lucky enough, you project could just compile with cargo build command! But for the most of the cases, there are minor modifications you have to do. There are two ways to use config your RMK keyboard in your firmware project:

• use a config file: keyboard.toml

  For new users, it's recommend to use keyboard.toml to config your keyboard. This config file contains almost all about your keyboard, with it, you can create your firmware very conveniently, no Rust code needed! Please check Keyboard Configuration feature for configuration details.

• use Rust code

  If the configuration doesn't satisfy all your needs(it would mostly do!), you can write your own Rust code to do more customization! RMK also provides some examples to help you quickly get throught it.
