How to create a thread. Creating a new thread is the most common development task when using an RTOS, this is how it is done in ChibiOS/RT. MCU specific!! Lets use some power of the Chibios. Chibios has its own plugin inside the Chibistudio. Here’s a quick tutorial on how I created a new project in ChibiStudio preview 6. Brief: I used the STM32F4 Discovery Board for this example.

This threads usually switches the system in a low power mode and does nothing else. Try the video tutorials and guides on Play Embedded. Products Downloads Documentation Articles Licensing. Java Runtimeyou probably already have this installed. This macro reserves bytes of stack for the thread and space for all the required thread related structures. Verify if you have Java installed, if not install the runtime.

ChibiOS free embedded RTOS – Setting up an Eclipse-based IDE

Try the video tutorials and guides on Play Embedded. Create an eclipse directory in your home and unpack the archive there. The forums is the best place, registration required. You may verify this using the command: Eclipse will ask you a directory for tutorixl initial workspace, make it point to the ChibiOS root directory you may have as many workspaces you want, keep this for latermake sure to select the check box or it will ask you again each time.


An RS levels translator. The first thing to do is to download all the required software components, beginners should avoid the optional components initially.

Getting started with the STM32F4-Discovery and ChibiOS

Try the video tutorials and guides on Play Embedded. The result of what is described here can also be downloaded as a single package called ChibiStudio which includes the toolchain and all ChibiOS demos already imported into a workspace.

What this guide does not cover This guide will not enter into details of common system tasks like and not limited to: It is required only if you want to capture the test report from the USART1 port using a terminal emulator, for example the in famous HyperTerminal. Linux users should follow the normal installation procedure for deb or rpm packages, of course it is also possible to build it from the source code.

Note that the memory allocated to myThread is statically chkbios and cannot be reused. Windows users simply have to use the installers, just make sure that the directories containing arm-none-eabi-gcc.

A static thread can be started by invoking chThdCreateStatic as shown in this example:.

This thread has the lowest priority in the system so it runs only when the other threads in the system are sleeping.

The demo code can be previewed here. A list of compatible devices is available in the OpenOCD documentationmore exactly here. We will use it as workspace later. If you don’t need to debug but just want to upload the code on the board you may use the ST Visual Programmer tool. Windows users may download it from the Freddie Chopin’s homepageLinux and Mac users probably will have to build from source.


It is only required if you want to see the SPI output. You will see both user LEDs flashing with an one second period, the green LED duty cycle can be adjusted using the potentiometer, the blue LED duty cycle is determined by the temperature and is driven by the STM32 internal sensor.

I bought the one in the tuotrial here. More Articles and Guides More articles and guides are available on the technical wiki. It is from the main thread that the other threads are usually created.

Threads created by allocating memory at run time from a memory heap or a memory pool.

This class of threads are statically allocated in memory at compile time. In general any probe supporting a decent GDB server is usable. Board features This board is impressive when compared to the cost. Now a complete example:. The forums is the best place, registration required.

The memory is allocated from the specified heap and the ttorial is started.
