Chronicles from our peeps.
I would like to look deeper into the application of FreeRTOS interrupts on the latest version of AEMB. It is important to be able to clearly identify the context switching by the interrupt on both threads of AEMB. To look more into the interrupts, the tasks are written with longer Read more
The task priority of FreeRTOS is tested on the new AEMB processor. The previous programs tested all contains tasks of equal priorities with the idle task. Therefore, higher priority tasks are to be tested to see their effect on the new AEMB processor. Will the higher priority tasks act independent Read more
This week, I set my mind on understanding on the switching of tasks inside FreeRTOS on the latest AEMB with two threads. From previous week, it was found that there was an infinite loop which act upon the second thread while the first thread will continue with FreeRTOS and all Read more
This week the focus was given on trying to develop a simple simulation to test out one of the algorithms discussed the previous week. The algorithm used to try out the simulation was the Uniform Dispersion algorithm. Some work was also done in the aspect of a proposed design for Read more
This week main project is to port FreeRTOS to the newer AEMB. In the previous weeks, the AEMB processor only fully utilizes one thread. It was the older version and the newer version actually fully utilizes two threads. I was instructed to make the necessary changes so that FreeRTOS will Read more
FreeRTOS was created using C. C++ offers something more than C, which are object oriented and inheritance. This is shown by the usage of class. By using class, users can create their task by simply creating the object of the class. To implement the class, I need to understand the Read more
As it turns out, there was some redundant things that I did during the upgrade to FreeRTOSV8.0.1 for AEMB2. What I did wrong last time was that I added the commits from upstream into the git repository. This was actually not required as the commits from upstream can be viewed Read more
FreeRTOS has been using C language as its base programming language ever since it started. So, we decided to try using C++ with FreeRTOS. One of the advantages which C++ provides to FreeRTOS is the usage of class. By using class, users can supposedly create task with less syntax and Read more
This past week was a great struggle to try to get the quad copter to talk back to the Arduino. As discussed last week, the Arduino library DZL was tested with the NRF24L01 but the quad copter could not bind with the Arduino, or rather with the communication protocol set Read more
As mentioned in the previous post, the AEMB code has to be updated. The AEMB Demo code needs to be able to run on the latest FreeRTOS V8.0.1. There are a lot of changes since V7.1.1. and these changes need to be implemented on AEMB as well. First of all, Read more
