// Copyright 2021 The gd32f1x0-hal authors. // // SPDX-License-Identifier: MIT OR Apache-2.0 //! # HAL for the GD32F1x0 family of microcontrollers //! //! This is an implementation of the [`embedded-hal`] traits for the GD32F1x0 family of //! microcontrollers. //! //! [`embedded-hal`]: https://crates.io/crates/embedded-hal //! //! # Usage //! //! ## Building an application (binary crate) //! //! A detailed usage guide can be found in the [README] //! //! ## Variants //! //! This crate supports multiple microcontrollers in the GD32F1x0 family. Which specific //! microcontroller you want to build for has to be specified with a feature, for example //! `gd32f130x8`. //! //! If no microcontroller is specified, the crate will not compile. //! //! The currently supported variants are //! //! - `gd32f130x4` (e.g. GD32F130F4, GD32F130G4, ...) //! - `gd32f130x6` (e.g. GD32F130F6, GD32F130G6, ...) //! - `gd32f130x8` (e.g. GD32F130F8, GD32F130G8, ...) //! //! ## Commonly used setup //! Almost all peripherals require references to some registers in `RCU`. The following //! code shows how to set up those registers //! //! ```rust //! // Get access to the device specific peripherals from the peripheral access crate //! let dp = pac::Peripherals::take().unwrap(); //! //! // Take ownership over the raw RCU and FMC devices and convert tem into the corresponding HAL //! // structs. //! let mut rcu = dp.RCU.constrain(); //! let mut flash = p.FMC.constrain(); //! //! // Freeze the configuration of all the clocks in the system and store the frozen frequencies in //! // `clocks` //! let clocks = rcu.cfgr.freeze(&mut flash.ws); //! ``` //! //! ## Usage examples //! //! See the [examples] folder. //! //! Most of the examples require the following additional dependencies //! ```toml //! [dependencies] //! embedded-hal = "0.2.3" //! nb = "0.1.2" //! cortex-m = "0.6.2" //! cortex-m-rt = "0.6.11" //! # Panic behaviour, see https://crates.io/keywords/panic-impl for alternatives //! panic-halt = "0.2.0" //! ``` //! //!
