QUESTION
I'm currently trying to learn Rust (for embedded specifically), coming from a background of C for embedded systems and Python. So far, I've been reading Rust Programming Language and Rust for Embedded, and read a few blog posts on the web.
I want my first project to be a simple "Blinky", where an LED blinks infinitely. I've got an STM32L152CDISCOVERY board with an STM32L152 chip in it (basically same as STM32L151), which is a Cortex M3.
Instead of implementing everything from scratch, I want to leverage existing crates and HALs. I've found two that seem promising: stm32l1 and stm32l1xx-hal. I've tried to read the documentation of each of them and also part of the source code, but I still can't figure out how to use them correctly.
Got a few questions about Rust and about the crates:
I see that
stm32l1xx-hal
has a dependency onstm32l1
. Do I need to add both as a dependency in myCargo.toml
file? Or will that create problems related to ownership?Is this the correct way to add them? Why is the second one added like that
...[dependencies.stm32l1]
?

stm32l1xx-hal
already depends onstm32l1
as seen here. There's no need to import it twice. It is enough to add to Cargo.toml:

Answered 2019-May-31 at 14:24Your code works fine on the Rust playground, so I recommend checking your Rust installation and environment settings.
You may want to use the preconfigured Rust Docker image to run your app. Have Docker installed, then:
