//! This is the **H**ardware **A**bstraction **L**ayer (HAL) for the VA416xx MCU family.
|
|
//!
|
|
//! It is an additional hardware abstraction on top of the [peripheral access API](https://egit.irs.uni-stuttgart.de/rust/va416xx-rs/src/branch/main/va416xx).
|
|
|
|
//! It is the result of reading the datasheet for the device and encoding a type-safe layer over the
|
|
//! raw PAC. This crate also implements traits specified by the
|
|
//! [embedded-hal](https://github.com/rust-embedded/embedded-hal) project, making it compatible with
|
|
//! various drivers in the embedded rust ecosystem.
|
|
|
|
//! You have to enable one of the following device features to use this crate depending on
|
|
//! which chip you are using:
|
|
|
|
//! - `va41630`
|
|
//! - `va41629`
|
|
//! - `va41628`
|
|
//! - `va41620`
|
|
//!
|
|
//! When using this HAL and writing applications for the VA416xx family in general, it is strongly
|
|
//! recommended that you set up the clock properly, because the default internal HBO clock
|
|
//! is not very accurate. You can use the [crate::clock] module for this. If you are working
|
|
//! with interrupts, it is strongly recommended to set up the IRQ router with the
|
|
//! [crate::irq_router] module at the very least because that peripheral has confusing and/or
|
|
//! faulty register reset values which might leads to weird bugs and glitches.
