Codal target for the STM32 familly. Codal is the core set of drivers, mechanisms and types that make up the runtime for a board in Makecode.

The codal runtime provides an easy to use environment for programming the board in the C/C++ language, written by Lancaster University. It contains device drivers for all the hardware capabilities, and also a suite of runtime mechanisms to make programming the easier and more flexible. These range from control of the LED matrix display to peer-to-peer radio communication and secure Bluetooth Low Energy services.

In addition to supporting development in C/C++, the runtime is also designed specifically to support higher level languages provided by our partners that target physical computing and computer science education. It is currently used as a support library for Microsoft MakeCode

Codal-core must be implemented by third party developper to support new hardware target. This repository constain the codal implementation for the STM32 MCU familly.

This porting is based on:

• STM32Cube MCU Packages including:
  • The HAL hardware abstraction layer, enabling portability between different STM32 devices via standardized API calls
  • The Low-Layer (LL) APIs, a light-weight, optimized, expert oriented set of APIs designed for both performance and runtime efficiency
  • CMSIS device defintion for STM32
• CMSIS: Cortex Microcontroller Software Interface Standard (CMSIS) is a vendor-independent hardware abstraction layer for the Cortex®-M processor series and defines generic tool interfaces. It has been packaged as a module for Arduino IDE: https://github.com/stm32duino/ArduinoModule-CMSIS
• GNU Arm Embedded Toolchain: Arm Embedded GCC compiler, libraries and other GNU tools necessary for bare-metal software development on devices based on the Arm Cortex-M. Packages are provided thanks The xPack GNU Arm Embedded GCC: https://github.com/xpack-dev-tools/arm-none-eabi-gcc-xpack
