Well Im more like at early stage than a beginner to free RTOS… & out from no where and without any kinda of helping material I hv got an assignment from my tutor to perform the following.
The complete scenario is as follows:
Microcontroller to be used: PIC 18F452.
Software Development IDE : MPLAB from Microchip
Hardware Software Simulator: Proteus Simulator
Compiler: Microchip C18 Lite Compiler
RTOS: FreeRTOS
Application Description is as follows:
A task called my_task1 is receiving data from the PORTA through port change
interrupt using credit tracking synchronization and sends average of last four
samples to my_task2. my_task2 will receive this sample and send it to PORTB
which has LEDs connected to it. There are other three tasks namely my_task3,
my_task4 and may_task5 which need mutually exclusive access to PORTD. The
function of my_task3 is to send 0x00 to PORTD every 100 mili-seconds, my_task4
is to send 0x0F to PORTD every 500 mili seconds and my_task5 is to send 0xFF
every 1000 mili seconds. During implementation use timing services provided by
the RTOS whenever applicable and don’t use your own delay routines.
Seriously I dont want you people to do it for me, but I dont know anytthing about it, I just want you people me drive me through… I will be very grateful…
