lpc546xx-hal

Hardware Abstraction Layer crate for the lpc546xx family.

This crate relies on the lpc546xx-pac crate to provide appropriate register definition and implements a partial set of embedded-hal traits.

Usage

Add the lpc546xx-hal crate to your dependencies in your Cargo.toml and make sure to pick the appropriate mcu-* feature to enjoy the full feature set for your MCU.

For example, for the LPCXpresso54608 board that sports a LPC54608J512ET180:

lpc546xx-hal = { version = "0.2.0", features = ["mcu-LPC54608J512ET180", "rt"] }

This will select the appropriate memory.x linker script depending on both your RAM and FLASH, the correct feature set from the peripheral access crate, and the correct interrupt vector for your device. You can disable this feature using the disable-linker-script feature.

If you look into Cargo.toml file, you will see the supported devices.

If you want to run an example, you can run it by using:

$ cargo run --example gpio --features=mcu-LPC54608J512ET180,rt  

This HAL will also include a __pre_init stub in src/lib.rs to be called by cortex-m-rt when the "rt" feature is enabled. In this stub all the rams are turned on. You can disable this feature by using the disable-pre-init-blob feature. But you should do it yourself, otherwise your program will not boot, as cortex-m-rt will try to init memory regions that are not enabled.

Toolchain Setup

In order to use this HAL, you need the following Setup:

1. Install Rustup

   See rustup.rs for details. You may als be able to install Rustup directly through your distro.

2. Install the arm-none-eabi compiler toolchain

   https://developer.arm.com/open-source/gnu-toolchain/gnu-rm/downloads

   If you cannot install the toolchain directly through your OS / distro, we recommend installing the precompiled binaries to '/usr/local/opt'. Add the bin folders (/bin & /arm-none-eabi/bin) to your environments variable 'PATH'.

3. Install the thumbv7em-none-eabi/hf target for Rust

   Simply run rustup target add thumbv7em-none-eabi or rustup target add thumbv7em-none-eabihf

For more instructions on how to get started with ARM / Cortex-M programming using Rust, check out the Embedded Rust Book.

Build Examples

You can build examples through Cargo:

$  cargo build --example gpio --features="mcu-LPC54608J512ET180,rt"  

Note that not all examples are compatible with all MCUs. You might need to peek into the example source code.
