This project provides a task scheduler for STM32F407 microchips. It manages multiple tasks on your hardware without extra operating systems. It uses direct code to control memory and hardware cycles. This approach ensures your processor runs tasks predictably and saves power.
Your computer needs the following items to run this project:
Follow these steps to obtain the files for your device:
Prepare your STM32 hardware before you transfer the data. Connect your board to the computer using the primary USB port. Ensure the power light on the board glows. If your computer does not recognize the device, check the cable connection. You may need to install standard USB drivers for the ST-Link tool if your computer does not see the board at first.
Use your ST-Link utility to move the downloaded file onto the chip. Open your utility software and select the file you saved earlier. Click the program button to write the data. Once the progress bar reaches one hundred percent, the green light on your board will blink. This confirms the scheduler runs correctly. The system now manages its internal tasks using the round-robin method.
This project relies on a low-level technique called context switching. When the processor finishes one task, it saves the current state and starts another task. This happens very fast. The result is that your board appears to do many things at the same time. We avoid large operating systems to keep the footprint small and the execution fast. This offers total control over your hardware resources.
Do I need to install a compiler? No, you only need the compiled binary file from the download page.
Can I use this on other chips? This version works specifically with the STM32F407 model. Using it on a different chip might stop the hardware from booting.
How do I stop the schedule? Simply disconnect the power source or press the reset button on your development board.
