CMSIS-DAP¶
CMSIS-DAP is generally implemented as an on-board interface chip, providing direct USB connection from a development board to a debugger running on a host computer on one side, and over JTAG (Joint Test Action Group) or SWD (Serial Wire Debug) to the target device to access the Coresight DAP on the other. Official reference can be found here.
Configuration¶
You can configure debugging tool using debug_tool option in “platformio.ini” (Project Configuration File):
[env:myenv]
platform = ...
board = ...
debug_tool = cmsis-dap
If you would like to use this tool for firmware uploading, please change upload protocol:
[env:myenv]
platform = ...
board = ...
debug_tool = cmsis-dap
upload_protocol = cmsis-dap

Drivers¶
- Windows:
Please install Windows serial driver and check “USB Driver Installation” guide for your board.
- Mac:
Not required.
- Linux:
Please install “udev” rules 99-platformio-udev.rules. If you already installed them before, please check that your rules are up-to-date or repeat steps.

|
The Nordic nRF51 Series is a family of highly flexible, multi-protocol, system-on-chip (SoC) devices for ultra-low power wireless applications. nRF51 Series devices support a range of protocol stacks including Bluetooth Smart (previously called Bluetooth low energy), ANT and proprietary 2.4GHz protocols such as Gazell. |
|
The nRF52 Series are built for speed to carry out increasingly complex tasks in the shortest possible time and return to sleep, conserving precious battery power. They have a Cortex-M4F processor and are the most capable Bluetooth Smart SoCs on the market. |
|
The NXP LPC is a family of 32-bit microcontroller integrated circuits by NXP Semiconductors. The LPC chips are grouped into related series that are based around the same 32-bit ARM processor core, such as the Cortex-M4F, Cortex-M3, Cortex-M0+, or Cortex-M0. Internally, each microcontroller consists of the processor core, static RAM memory, flash memory, debugging interface, and various peripherals. |
|
The STM32 family of 32-bit Flash MCUs based on the ARM Cortex-M processor is designed to offer new degrees of freedom to MCU users. It offers a 32-bit product range that combines very high performance, real-time capabilities, digital signal processing, and low-power, low-voltage operation, while maintaining full integration and ease of development. |
|
The IOP (Internet Offload Processor) W7500 is the one-chip solution which integrates an ARM Cortex-M0, 128KB Flash and hardwired TCP/IP core for various embedded application platform especially requiring Internet of things |
Frameworks¶
Name |
Description |
|---|---|
Arduino Wiring-based Framework allows writing cross-platform software to control devices attached to a wide range of Arduino boards to create all kinds of creative coding, interactive objects, spaces or physical experiences. |
|
The ARM Cortex Microcontroller Software Interface Standard (CMSIS) is a vendor-independent hardware abstraction layer for the Cortex-M processor series and specifies debugger interfaces. The CMSIS enables consistent and simple software interfaces to the processor for interface peripherals, real-time operating systems, and middleware. It simplifies software re-use, reducing the learning curve for new microcontroller developers and cutting the time-to-market for devices. |
|
The libOpenCM3 framework aims to create a free/libre/open-source firmware library for various ARM Cortex-M0(+)/M3/M4 microcontrollers, including ST STM32, Ti Tiva and Stellaris, NXP LPC 11xx, 13xx, 15xx, 17xx parts, Atmel SAM3, Energy Micro EFM32 and others. |
|
The mbed framework The mbed SDK has been designed to provide enough hardware abstraction to be intuitive and concise, yet powerful enough to build complex projects. It is built on the low-level ARM CMSIS APIs, allowing you to code down to the metal if needed. In addition to RTOS, USB and Networking libraries, a cookbook of hundreds of reusable peripheral and module libraries have been built on top of the SDK by the mbed Developer Community. |
|
Simba is an RTOS and build framework. It aims to make embedded programming easy and portable. |
|
The ST Standard Peripheral Library provides a set of functions for handling the peripherals on the STM32 Cortex-M3 family. The idea is to save the user (the new user, in particular) having to deal directly with the registers. |
|
STM32Cube embedded software libraries, 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. |
|
The Zephyr Project is a scalable real-time operating system (RTOS) supporting multiple hardware architectures, optimized for resource constrained devices, and built with safety and security in mind. |
