Zinc is an experimental attempt to write an ARM stack that would be similar to CMSIS or mbed in capabilities but would show rust's best safety features applied to embedded development.
Zinc is mostly assembly-free and completely C-free at the moment. One of the goals of zinc is to figure out, how much of the usual RTOS stack is it possible to write in rust in a safe manner, while keeping the resource usage profile low enough (comparable to C/C++ code).

Zinc provides you with safe code in terms of rust code safety; accessing hardware directly is unsafe, but you can do that as well if you want.
In addition to software safety, zinc provides hardware safety with Platform Tree specification; you define the hardware configuration right in the code in simple key-value DSL and compiler verifies that all hardware is configured properly; that also allows to optimize the code to much bigger extent than with conventional RTOSes.
Zinc supports only ARM at the moment. The primary development is focused on two test boards with NXP LPC1768 and ST STM32F407. Other MCUs will follow when core API is stabilized.
Zinc is distributed under Apache-2.0, see LICENSE for more details.
Get a gcc cross-toolchain for arm and make sure it is accessible.
First, generate a Makefile and .cargo/config with configure so cargo
can find your toolchain. Your toolchain triple is probably arm-none-eabi
./configure PLATFORM=<platform> --host=<toolchain-triple>
To build an application from examples/ use the following command after having
run configure:
EXAMPLE_NAME=<example> make build
Ouput will go to target/<target-triple>/release/examples.
