* Start on STM32 DMA SPI * Update all objects.hs, add interrupt function * Initial DMA code should be ready to test out... * Fix SPI interrupt-mode IRQ handlers, add SPI::transfer_and_wait * Fix CMake error when building for STM32WL processors * Now builds on all STM devices! * Properly support STM32U5 / DMA IP v3 * Start on STM32F4 support, fix hardfault on IP v1 and v3 due to incorrect indexing * Fix Rx-only transfers, add abort code, fix incorrect channel assignments for DMA IP v1 devices * Start on STM32H7 SPI DMA * Fixes for H7: Correctly manage data cache, keep SPI ISR enabled * Implement DMA SPI header constants for all remaining STM32 families. Also add support for freeing DMA channels * Try and fix build on STM32G0 * Fix build on STM32G0 * Add SPI_32BIT_WORDS label, start on fixing SPI docs * SPI: Implement reference counting so that DMA channels get freed properly * Fix issue where SPI data could get corrupted (by TI mode turning on) depending on memory layout (if your spis pointer & 0x10 was nonzero) * Mark DMA channels as unallocated when SPI bus is freed * Simplify spi_abort_asynch() * Fix some rebase issues, fix failing to allocate DMA channel on STM32U5 * Fix DMA getting stuck on STM32F4, F7, and F2 |

Mbed OS Community Edition
Arm Mbed OS is an open source embedded operating system designed specifically for the "things" in the Internet of Things. It includes all the features you need to develop a connected product based on an Arm Cortex-M microcontroller, including security, connectivity, an RTOS and drivers for sensors and I/O devices.
Mbed OS provides a platform that includes:
- Security foundations.
- Cloud management services.
- Drivers for sensors, I/O devices and connectivity.
This is Mbed OS Community Edition (CE), a fork focused on improving the build system and tooling, fixing bugs, and keeping maintenance going after ARM's step back from the Mbed project.
License and contributions
The software is provided under the Apache-2.0 license. Contributions to this project are accepted under the same license. Please see contributing.md for more information.
This project contains code from other projects. The original license text is included in those source files. They must comply with our license guide.
Folders containing files under different permissive license than Apache 2.0 are listed in the LICENSE file.
Getting started for developers
To start a new project that uses Mbed CE, see the setup guide here.
We have a developer website for asking questions, engaging with others, finding information on boards and components, using an online IDE and compiler, reading the documentation and learning about what's new and what's coming next in Mbed OS.
Additionally, the discussions page on this repo can be used for proposing and discussing specific code changes.
Documentation
For more information about Mbed OS, please see the published Mbed OS documentation. It includes general overview information, step-by-step tutorials, porting information and background reference materials about our architecture and tools.
For the Mbed OS CE code-level documentation (Doxygen), see here
