CooCox——Free and open ARM Cortex-M3&M0 embedded development tools

CooCox is a series of embedded development tools which are Free and Open for ARM Cortex-M3 and Cortex-M0 based MCUs. It consists of a highly-integrated software development environment CoIDE, an embedded real-time multi-task OS CoOS, debugging probes Colink&ConLinkEx, a stand-alone flash programming software CoFlash, and a register assistant CoAssistant.

The core is CoIDE, for it has all the other softwares, except for CoFlash, integrated in it.

Apart from free, CoIDE is very easy and convinient to use. CooCox has abstracted boot codes, peripherals libraries, drivers and OS into specific components for some chip, and supported over 152 examples of all the peripheral modules. Only by ticking off the components you use and adding examples, you can set up a new usable project in a very short time, sometimes even less than 5 minutes.

You can also upload your own code to CoIDE. If it's passed, then other users can download and use your work.CooCox-Free and Open-source components and example code download

Open CoAssistant through " View->Peripherals ". You can read/Write the value of registers when debugging.

CooCox CoIDE-----393 components + 327 examples = A fulcrum for moving the world

"Give me a fulcrum," Archimedes is reported to have said, "and a place to stand—and I will move the world." In the field of ARM Cortex-M3&Cortex-M0 embedded development, CooCox CoIDE has provided all its users with a free fulcrum. According to the latest data, this fulcrum = 393 components + 327 examples.

As a user-friendly software, CoIDE has abstracted boot codes, peripherals libraries, drivers and OS into a great many components, most of which have corresponding examples. With CoIDE, users only need to select components and add examples to build a usable project.

When everyone adds fuel the flames rise high. The current components and examples were not only provided by CooCox, but also uploaded by the users, all marked with authors of course. There is no denying that the fulcrum will upgrade continuously with the joint efforts of CooCox and users.

CoIDE is Eclipse-based and uses GCC compiler, and it’s easy to port a project from other IDE to CoIDE. A porting example: Porting CodeLite project to CoIDE « CooCox Forum

List of Chips Supported By The Components&Examples-----
  • Atmel: AT91SAM3Ux
  • Energy Micro: EFM32G2xx, EFM32G8xx
  • NXP: LPC11c1x, LPC11xx, LPC13xx, LPC17xx
  • Nuvoton: NUC100, NUC120, NUC130, NUC140, NuMicroM051 series
  • ST: STM32F100x, STM32F101x, STM32F102x, STM32F103x, STM32F105x, STM32F107x
  • TI: LM3S19xx, LM3S2xxx, LM3S3xxx, LM3S5xxx, LM3S6xxx, LM3S8xx, LM3S8xxx, LM3S9xxx

P.S.: About Examples
  • After selecting a component, the top left window in CoIDE will show component name(with * examples). Click it and you’ll see the Example window, where there are 327 examples in total.
  • Click some component, and the Help window will show the component’s information, some of which include a Hello world item, i.e. a simple example of the component.
So in fact the number of the examples is over 327.

Projects (source code ALL FREE) of MDK/IAR/CoIDE based on CoOS

After an introduction of CoIDE, today I’d like to share another CooCox member with you, which is even more popular than CoIDE-----CooCox CoOS. CoOS is an embedded real-time multi-task OS customized for ARM Cortex M series.

The reasons of my recommendation are as follows:
  • Free and open real-time Operating System
    Free is on behalf of “the poor”, and Open aims at speeding up the burst of new ideas.
  • Specially designed for Cortex-M series
    CoOS supports ALL Cortex-M0&Cortex-M3 chips.
  • Scalable, minimum system kernel is as small as 974Bytes
    The file OsConfig.h includes all configurable and able-to-be-cut items in CoOS. Users can modify items according to needed configuration simply and conveniently.
  • Adaptive Task Scheduling Algorithm
  • Supports preemptive priority and round-robin
    CoOS supports two kinds of scheduling mode, preemptive priority and round-robin. The former is used among tasks of different priority, while the latter among tasks of the same priority. You can set CFG_PRIORITY_SET_EN as 1 in OsConfig.h to enable the preemptive priority scheduling mode.
  • Interrupt latency is next to 0
  • Stack overflow detection option
  • Semaphore, Mutex, Flag, Mailbox and Queue for communication & synchronization
    In mutex section, CoOS has considered the issue of priority inversion, and solved it by the method of priority inheritance.
  • Supports the platforms of ICCARM, ARMCC, GCC
    This means CoOS can not only be used in CoIDE (by selecting CoOS component), but also used independently in MDK and IAR.

Here is the main course-----Examples & Application Solutions based on CoOS(MDK & IAR & CoIDE projects with all source code free)
Also, a simple and easy-to-understand user’s guide of CoOS is provided.

Changes about J-link, Include Paths and MDK projects in CoIDE 1.3.0

Hi All,

1. Many users of CoIDE 1.2.5 fed back that they couldn't use J-link due to the limit of J-link licence and jflash script. Thus in the new version, we modified J-link debugging part, so that a program can download automatically when debugging.

CoIDE 1.3.0 has removed the functions of direct download and erase with J-link. We will add them in next version.

For more details, you can refer to How to use J-link.

2. CoIDE 1.3.0 has added this function:

When compiling, CoIDE will automatically search all folders under project directory, including Linked Folder. All header files(if any) in the Linked Folder will be added automatically to Include Paths.

You can manually add directories needed to Include Paths in build.xml, or change the name of Linked Folder, or modify include sentences.

Sometimes you may need to build new projects or open repeatedly to make your previous projects work.

3. When converting a MDK project, code files related with compiler are not copied along. So there may be some problems with project building. We will solve this in the future.

CoIDE User’s Guide on line has been updated. Click Free ARM Cortex M3 and Cortex M0 IDE to have a look.

I downloaded CooCox IDE it seems to be good. Anyways I am more interested to know about the CooCox RTOS.

Can you provide some more details about it other than the details mentioned in the site.

Notice when using J-link editing script function and Include Paths

CoIDE V1.3.0 has firmed the init-script of debug (including Reset Mode and Run to main option) to code, so the Edit scripts box is empty, and users only need to fill in some GDB settings script.

The Other-adapter option was set according to the settings for J-link. After the modification of J-link part, we cancelled this option. A user has successfully support LPC-link (LPCXpresso) with CoIDE by editing script- Tip on using CoIde with LPC-Link (LPCXpresso) « CooCox Forum
Some users fed back that Include Paths added manually couldn’t be saved if the files were outside the project directory. We will fix the bug in next version.

To avoid this bug, you can use the function of Add Linked File / Add Linked Folder (right click project name or click File on toolbar).

Some fed back that all c files in the project directory are automatically compiled and linked. In next version of CoIDE, we will modify this and add a function of excluding files from a project without deleting them.

PS: Some user has made a wish list for CooCox Whishlist for CoIDE « CooCox Forum.
What's on your mind? Tell CooCox.

How to Debug in RAM in CoIDE 1.3.0

CoIDE 1.3.0 has added “Debug in Flash” and “Debug in RAM” options to file build.xml.
“Debug in Flash” is by default. To debug in RAM, you need some extra settings. For different chips, the settings are different.

For instance,
  • STM32F10X series
    In function SystemInit(), file system_stm32f10x.c, folder cmsis_boot, there are sentences as follows:
    #ifdef VECT_TAB_SRAM
    SCB->VTOR = SRAM_BASE | VECT_TAB_OFFSET; /* Vector Table Relocation in Internal SRAM. */
    SCB->VTOR = FLASH_BASE | VECT_TAB_OFFSET; /* Vector Table Relocation in Internal FLASH. */

    So you just need to select “Debug in RAM” in file build.xml, and add VECT_TAB_SRAM to Defined symbols.

  • LPC17xx series
    In function SystemInit(), file system_LPC17xx.c, folder cmsis_boot, there are sentences as follows:
    #if (__RAM_MODE__==1)
    SCB->VTOR = 0x10000000 & 0x3FFFFF80;
    SCB->VTOR = 0x00000000 & 0x3FFFFF80;

    So you just need to select “Debug in RAM”, and add one sentence to file system_LPC17xx.c -
    #define __RAM_MODE__ 1

  • Chips which have no sentences above, e.g. LM3S series
    After selecting “Debug in RAM”, add one sentence to function SystemInit() in file system_lm3s.c, folder cmsis_boot -
    SCB->VTOR = 0x20000000 | 0x0; /* Vector Table Relocation in Internal SRAM. */

    Since VTOR is defined in file core_cm3.h, you need to add one sentence as well -
    #include "core_cm3.h"
