Accomplished
The high-level architecture of our project will involve the ESP32-S3 acting mainly as the data source and an STM32W series board acting as the data receiver. Both of these microcontrollers will need some sort of RTOS running to manage complexity and ensure the system is responsive and reliable
This week, I looked into how we would set up FreeRTOS on each microcontroller. We want to use FreeRTOS since it is a small and open-source real-time operating system that can simplify task management and scheduling for both of our MCUs.
I found that the development framework for ESP32-S3 is already built upon FreeRTOS, so it is possible to just use features like tasks, queues, and semaphores in our code development. FreeRTOS also already supports use on certain development boards such as STM32s, so I watched a video on how we would begin writing tasks and handle scheduling on STM32 after some setup on STM32CubeIDE, which is an IDE for STM boards.
Here is the link for the tutorial for next steps.
Progress / Schedule
My progress is on schedule, as we wanted to spend this week investigating FreeRTOS compatibility and setup on the microcontrollers. This will end up extending into next week of actually setting up our development environments and FreeRTOS on the hardware.
Deliverables / Next Steps
Next week, I will:
- follow the tutorial to setup FreeRTOS for an STM32 board that we have readily available such as the STM32F401xE.
- outline and plan what types of tasks we will need on the TX and RX MCUs. This will include identifying what initialization and run will look like for each task, as well as task priority.
- set up a Git repository for the team so that we can begin collaborative development.
