WebInter-task communication and synchronisation mechanisms in FreeRTOS including queues, mutexes, binary semaphores, counting semaphores and recursive semaphores Webmain.c - initialises the hardware, creates the demo application tasks, then starts the RTOS scheduler. http_serv.c - handles the sequencing of the socket creation and incoming connections. This is a very simply file. tcp.c - handles all the messaging between the server task and the WIZnet module. Refer the to the WIZnet W3100A datasheet. WebRTOS model achieves time-accurate task preemption via Sys-temC events and models time passing via a delay() method. The RTOS overhead can be modeled as well. Two di erent task scheduling schemes are studied: the rst one uses a dedicated thread for the scheduler, while the second is based on cooperative procedure calls, avoiding this overhead.
