Blanket impls for &mut can cause trait methods to be preferred over inherent methods.

2

I found one ugly side effect of the `&mut` blanket impls while experimenting updating stm32f4xx-hal's GPIO. it's making the trait methods take priority over the inherent methods in some cases:...

Add built-in no-op implementations for GPIO

Dummy `OutputPin`/`InputPin` implementations would be useful for implementing optional I/O pins. A dummy `OutputPin` would simply discard any value written to it, while a dummy `InputPin` would always return a...

Implement all I2C traits for `&RefCell`

1

This allows an I2C bus to safely be shared between device drivers. Note that it does *not* allow the bus to be shared between threads/interrupts because `RefCell` is not `Sync`...

Solution for asserting infallibility of a Result<T, Infallible>

1

(From #328) Back in the days, before `core::convert::Infallible` was added, we had `void::Void` to mark `Result`s which cannot ever produce the error variant. With it came the `void::ResultExt` extension trait...

Solution for dealing with clocks and time in embedded systems

37

I have just released [`embedded-time`](https://github.com/FluenTech/embedded-time) to handle clocks, instants, durations more easily in embedded contexts. It follows a similar idea to the C++ `std::chrono` library. I'd love to get some...

I²C Polling (detecting NACKs)

Is there a hardware agnostic way for a driver to poll an I2C bus and return the information whether or not a NACK was received? This seems possible in the...

Need a unified way to specify frequencies / periods

A little while back I was trying to create a UART bitbang library. I took a look at https://crates.io/crates/bitbang-hal however it was incompatible since for nrf51, the Timers usable for...

TryInto instead of Into

https://github.com/rust-embedded/embedded-hal/blob/3dcb672bfcff83d8e672ae41cd203a9c6a9c8b4c/src/nb/timer.rs#L69 During moving to `embedded-time` I found `Into` is not implemented for `Kilo/Megahertz`

Will the serial interface support USB CDC implementations of serial like on the Arduino Leonardo?

2

The normal way of interacting with an Arduino Leonardo has a few interesting features: * The serial output goes over usb and is controlled by the same processor running your...
