stm32l0xx-hal

stm32l0xx-hal is a Hardware Abstraction Layer (HAL) for the STMicro STM32L0xx family of microcontrollers.

This crate relies on Adam Greig's stm32l0 crate to provide appropriate register definitions and implements a partial set of the embedded-hal traits.

Based on the stm32l1xx-hal crate by Vitaly Domnikov and the stm32f4xx-hal crate by Daniel Egger.

Supported Configurations

• stm32l0x1
• stm32l0x2
• stm32l0x3

Build Dependencies

1. Rustup toolchain installer

   https://rustup.rs

Toolchain Configuration

Using as a Dependency

To use the stm32l0xx-hal crate as a dependency, add the following definition to your Cargo.toml:

[dependencies.stm32l0xx-hal]
version = "0.5.0"
features = ["stm32l0x1", "rt"]

Dependecies for Flashing

1. Download and install the arm-none-eabi toolchain

   https://developer.arm.com/open-source/gnu-toolchain/gnu-rm/downloads We recommend installing the precompiled binaries to '/usr/local/opt'. Add the bin folders (/bin & /arm-none-eabi/bin) to your environments variable 'PATH'.

2. Install STLink Tool (>=v1.5.1)

   https://github.com/texane/stlink

3. Install OpenOCD (OPTIONAL)

   NOTE: OpenOCD v0.10.0 does not fully support the stm32l0 family MCU. We recommend using gnu-mcu-eclipse/openocd instead:

   https://gnu-mcu-eclipse.github.io/openocd/install/ We recommend installing the precompiled binaries to '/usr/local/opt'. Add the bin folders (i.e. - /usr/local/opt/gnu-mcu-eclipse/openocd/0.10.0-12-20190422-2015/bin) to your environments variable 'PATH'.

4. Install GDB Dashboard (OPTIONAL)

   https://github.com/cyrus-and/gdb-dashboard

Flashing

The following instructions outline how-to on flashing the 'serial' example code. This can be extended to any other example code.

Flashing with ST-Flash:

1. Flash the microcontroller using the flash script

   $ ./flash.sh target/thumbv6m-none-eabi/release/examples/serial
   

Flashing with OpenOCD

1. Flash the microcontroller using the openocd flash script

   $ ./openocd_flash.sh target/thumbv6m-none-eabi/release/examples/serial
   

Debugging

Debugging with GDB

1. Terminal 1 - OpenOCD Session:

   $ ./openocd_session.sh
   

2. Terminal 2 - GDB Session:

   $ ./gdb_session.sh target/thumbv6m-none-eabi/release/examples/serial
   

Debugging with GDB Py and GDB Dashboard

1. Terminal 1 - OpenOCD Session:

   $ ./openocd_session.sh
   

2. Terminal 2 - GDB Py Session:

   $ ./gdb_session.sh target/thumbv6m-none-eabi/release/examples/serial -d
   

   Note: Users can redirect the dashboard output to separate terminal (i.e. - ttys001) using:

   >>> dashboard -output /dev/ttys001
