Abstract:
In this work we evaluate the feasibility to use a Real Time Operating System
(FreeRTOS) on the CPU from electrocardiograph. This device is based on a microcontroller
platform that uses a PIC 18F4620 where the medical device functions are performed by the
microcontroller. The main objective for this research is check if the FREERTOS can be
embedded on this microcontroller, including its capabilities and resources. This work is based
on the results from other RTOS kernel running on the same platform. In this case we evaluated
RAM and ROM necessary to execute all device and kernel functions like semaphore and
queues for tasks synchronization. The processes or tasks to be evaluated were already checked
in previous experiences on other RTOS kernel. The final result is an electrocardiograph based
in a FreeRTOS Kernel.
