Component abstraction crates

The following crates provide HAL-like abstractions for subcomponents of embedded devices that go beyond what is available in embedded-hal:

• accelerometer - Generic accelerometer support, including traits and types for taking readings from 2 or 3-axis accelerometers and tracking device orientations -
• embedded-graphics: 2D drawing library for any size display -
• radio - Generic radio transceiver traits, mocks, and helpers -

Driver crates

You can also find many of these drivers on drive-rs; please consider adding your driver there (in the GitHub repo (⭐13)) while we work to port everything across.

Platform agnostic crates to interface external components. These crates use the embedded-hal interface to support all the devices and systems that implement the embedded-hal traits.

The list below contains drivers that have achieved the "released" status. To add a driver to this list, please ensure that your driver has a short blog post, article, or sufficiently explanatory README showing an example of its use. Ideally, this post would demonstrate using the device in a small project so that a Rust and/or embedded newcomer can also understand it. Otherwise, please add it to the WIP section below.

Panic handling

There are many ways to handle panics in embedded devices, these crates provide helpful variants.

1. dont_panic + dont_panic_slice: panic!()-like macro that causes linking error instead of panicking. May be used to statically ensure some code won't panic. +
2. no-panic: Attribute macro to require that the compiler prove a function can't ever panic.
3. panic-abort: Causes an abort on panics (nightly-only)
4. panic-halt: Halts the processor on panics
5. panic-itm: Prints the panic through the chip's ITM to a debugger attached to the SWO pin (Cortex-M with ITM only)
6. panic-never: This crate guarantees that your application is free of panicking branches.
7. panic-persist: A panic handler crate inspired by panic-ramdump that logs panic messages to a region of RAM defined by the user, allowing for discovery of panic messages post-mortem using normal program control flow. -
8. panic-probe: A panic handler that exits probe-run with an error code.
9. panic-ramdump: Writes the panic message into the beginning of RAM and enters an infinite loop; the message can be extracted by attaching a debugger (Cortex-M only)
10. panic-rtt: Set the panicking behavior to log to a JLINK debugger and loop.
11. panic-rtt-target: Logs panic messages over RTT. Uses rtt-target.
12. panic-semihosting: Prints the panic message via semihosting to an attached debugger (Cortex-M only)
13. rp2040-panic-usb-boot: Save panic message in XIP RAM and reboot RP2040 to USB mode
