msp432p401r-hal's Introduction

msp432p401r-hal

Hardware Abstraction Layer for MSP432P401R microcontroller

Currently under development:

Running the examples

Make sure you have OpenOCD and GNU ARM Embedded toolchain installed and up-to-date

$ brew install openocd --HEAD

Setup Rust nightly and add the ARM build platform target:

$ rustup default nightly
$ rustup target add thumbv7em-none-eabihf

Clone and compile the project:

$ git clone https://github.com/msp432-rust/msp432p401r-hal.git
$ cd msp432p401r-hal
$ example=hello_world
$ cargo build --example $example

Open a OpenOCD server and leave it open in a terminal:

$ openocd

On a separate terminal, open the GDB client:

$ arm-none-eabi-gdb -q target/thumbv7em-none-eabihf/debug/examples/$example
$ (gdb) target extended-remote :3333
$ (gdb) load
$ (gdb) monitor arm semihosting enable
$ (gdb) continue

msp432p401r-hal's Issues

Clock SMCLK Prescaler is incorrect

Hello,

Thanks for this crate. I am using a MSP432P401R and I encountered an issue with this crate.

The SMCLK prescalar for SMCLK is converted to u32, which is incorrect. For example, SMPrescaler::DIVS_0 as u32 is evaluated as 0, which actually indicates no scaling, i.e. a division of 1.

I'd be happy to contribute a PR. Can you please merge the hotfix PR #22 so I can fix this? My changes are based on the hotfix.

Thanks
