no-std crates

#![no_std] crates designed to run on resource constrained devices.

1. atomic: Generic Atomic wrapper type.
2. bbqueue: A SPSC, statically allocatable queue based on BipBuffers suitable for DMA transfers -
3. bitmatch: A crate that allows you to match, bind, and pack the individual bits of integers. -
4. biquad: A library for creating second order IIR filters for signal processing based on Biquads, where both a Direct Form 1 (DF1) and Direct Form 2 Transposed (DF2T) implementation is available.
5. bit_field: manipulating bitfields and bitarrays -
6. bluetooth-hci: device-independent Bluetooth Host-Controller Interface implementation.
7. bounded-registers A high-assurance memory-mapped register code generation and interaction library. bounded-registers provides a Tock-like API for MMIO registers with the addition of type-based bounds checking. -
8. combine: parser combinator library -
9. console-traits: Describes a basic text console. Used by menu and implemented by vga-framebuffer.
10. cmim, or Cortex-M Interrupt Move: A crate for Cortex-M devices to move data to interrupt context, without needing a critical section to access the data within an interrupt, and to remove the need for the "mutex dance" -
11. dcmimu: An algorithm for fusing low-cost triaxial MEMS gyroscope and accelerometer measurements
12. debouncr: A simple no-std input debouncer to detect rising/falling edges with minimal RAM requirements.
13. embedded-crc-macros: Macros implementing portable CRC algorithms and build-time lookup table generation.
14. embedded-websocket: A lightweight server and client websocket library for embedded systems.
15. endian_codec: (En/De)code rust types as packed bytes with specific order (endian). Supports derive. -
16. gcode: A gcode parser for no-std applications -
17. gdbstub: zero-allocation, pure Rust implementation of the GDB Remote Serial Protocol -
18. heapless: provides Vec, String, LinearMap, RingBuffer backed by fixed-size buffers -
19. ieee802154: Partial implementation of the IEEE 802.15.4 standard -
20. infrared: infrared remote control library for embedded rust -
21. intrusive-collections: intrusive (non-allocating) singly/doubly linked lists and red-black trees -
22. irq: utilities for writing interrupt handlers (allows moving data into interrupts, and sharing data between them) -
23. managed: provides ManagedSlice, ManagedMap backed by either their std counterparts or fixed-size buffers for #![no_std]. -
24. menu: A basic command-line interface library. Has nested menus and basic help functionality.
25. microfft: Embedded-friendly (no_std, no-alloc) fast fourier transforms -
26. micromath: Embedded Rust math library featuring fast, safe floating point approximations for common arithmetic operations, 2D and 3D vector types, and statistical analysis -
27. nalgebra: general-purpose and low-dimensional linear algebra library -
28. nom: parser combinator framework -
29. null-terminated: generic null-terminated arrays -
30. num-format: Crate for producing string representations of numbers, formatted according to international standards, e.g. "1,000,000" for US English -
31. 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. -
32. pc-keyboard: A PS/2 keyboard protocol driver. Transport (bit-banging or SPI) agnostic, but can convert Set 2 Scancodes into Unicode.
33. qei : A qei wrapper that allows you to extend your qei timers from a 16 bit integer to a 64 bit integer. -
34. qemu-exit: Quit a running QEMU session with user-defined exit code. Useful for unit or integration tests using QEMU. -
35. register-rs: Unified interface for MMIO and CPU registers. Provides type-safe bitfield manipulation. register-rs is Tock registers with added support for CPU register definitions using the same API as for the MMIO registers. This enables homogeneous interfaces to registers of all kinds. -
36. scroll: extensible and endian-aware Read/Write traits for generic containers -
37. smbus-pec: Minimal portable System Management Bus Packet Error Code calculation algorithm.
38. smoltcp: a small TCP/IP stack that runs without alloc.
39. static-bytes: Help work with buffers without dynamic allocation. Implement traits from bytes crate.
40. tinybmp: No-std, no-alloc BMP parser for embedded systems. Introductory blog post -
41. vga-framebuffer: A VGA signal generator and font renderer for VGA-less microcontrollers. Used by Monotron to generate 48 by 36 character display using 3 SPI peripherals and a timer.
42. wyhash: A fast, simple and portable hashing algorithm and random number generator. -
