Our goals are: Set up a development environment. Learn how to debug and upload code. Make an LED blink. The first thing to do is to set up a development environment.

More on this later. One thing to note is that a lot of the unused code is filtered out in the project settings, which can be found here: Once you start using any of these files eg. Next, you need to set up OpenOCD for debugging. This is already covered in the installation list.

Getting started with STM32 ARM Cortex-M3 using gcc (stm32f103, nucleo-f103rb)

But one thing I found to be missing is using OpenOCD to write the code to the flash memory of the chip. The above documents are all pretty cryptic, but fortunately there exists a great, free, comprehensible reference to get started on STM Discovering the STM32 Microcontroller by Prof. You could certainly skip these headers and code directly with register addresses given in the datasheet — if you are feeling particularly masochistic. Another fact is that this code is very easy to port across other chips from STMicroelectronics.

But the downside is that the code, being generic, covers a lot of stuff that may not apply to your specific use. One approach I can suggest is to use the Standard Peripheral Library, but not blindly. Read through the implementation of the functions you are using. When the need arises, write your own optimized functions that use just what you need. As before, peripheral clocks are enabled for these ports. Once you start using Standard Peripheral Library, the initialization scheme is quite uniform, so the code above is pretty much self-explanatory.

If the button is pressed, we set a flag val. To test the code, upload it the chip, open any serial communications application on your computer I use CoolTerm. The code above is far from robust. If you are using serial communications, you should probably use interrupts, for instance.

This hardware in most cases can be used to program external devices. It will be necessary to zoom the view out to see the trace details.

The bottom window displays the output of calls to printf. It is not intended to perform any useful functionality, or demonstrate how best to enhance application design by introducing multi-tasking. All the functions described below are defined in the main. Additional details can also be found in the comments within the source code itself.

The main Function main creates one queue and two tasks before starting the scheduler. It does not execute past the call to start the scheduler as from that point on the tasks themselves will be executing. The queue is used to pass a data value from one task the queue send task to the other task the queue receive task.

The queue receive task displays a string by calling printf each time a data value that equals is received on the queue. It should be noted that the 10 milliseconds value is relative to the simulated execution time not the observed time while the simulation is running. When data is received it checks the value of the data, and if the value equals the queue receive task outputs a string by calling printf.

The block time parameter passed to the queue receive function specifies that the task calling queue receive should be held in the Blocked state indefinitely to wait for data to be available on the queue. The queue receive task will only leave the Blocked state when the queue send task writes to the queue.

Because the queue send task writes to the queue every 10 milliseconds, the queue Real Time Engineers Ltd, The copyright of this document, which contains information of a proprietary nature, is vested in Real Time Engineers Ltd. For this project a very simple tracing scheme has been implemented to allow the sequence in which tasks execute to be viewed in the debuggers logic analyzer window.

The logic analyzer window has been configured to show three signals one representing each of the three tasks created in the simple demo application.

When the signal is high the task is running, when the signal is low the task is not running. As only one Cortex-M3 core is being simulated only one task can be running at any one time.

When no signals are high the kernel itself is running a high zoom level in the logic analyzer window is necessary to observe this. Referring to Figure 3 and Figure 4, The blue signal represents the Idle task.

The idle task is created automatically by the kernel itself. It can be seen that the Idle task is executing for the majority of the time.

It is periodically interrupted by the kernel tick interrupt. The green signal represents the queue send task. It runs every 10 milliseconds. The red signal represents the queue receive task. It runs each time the queue send task sends an item to the queue.
