3.7. Conclusion

We've completed our look at the FreeRTOS architecture. Hopefully you now have a good feel for how FreeRTOS's tasks run and communicate. And if you've never looked at any OS's internals before, I hope you now have a basic idea of how they work.

Obviously this chapter did not cover all of FreeRTOS's architecture. Notably, I didn't mention memory allocation, ISRs, debugging, or MPU support. This chapter also did not discuss how to set up or use FreeRTOS. Richard Barry has written an excellent book, Using the FreeRTOS Real Time Kernel: A Practical Guide, which discusses exactly that; I highly recommend it if you're going to use FreeRTOS.
