Hi,

I am a internship student. I am new to both the micro controller and FreeRTOS. I was task to integrate freeRTOS library into the system to achieve task management.

So far, what i did was understanding how freeRTOS work, looking into the details of the hardware of LPC-link 1769 and exploring LPCXpresso software.

Before i proceed, I would like to ask, is it possible to add LAN, WIFI and UART into the system? For LAN there is RD+,RD-,TD+,TD-. For UART, there is UART1/2/3-TX/RX. Can anyone enlighten me, for WIFI. what are the pin needed? Any idea how freeRTOS in general able to help this kind of real time communication

If anyone happen to see any projects that works on this kind of communication, will appreciate that you post the relevant link here to share.  And it will definitely speed up the process of gathering information and will also help future user. I am on internship, and its only 10 weeks, i dont wish to stuck in this project for long. there is more for me to learn :p

No, just make sure the missing files are on your include path.

No. Look at some of the ethernet projects in the examples I previously pointed you at.

I have to deal with networking communication, Do i have to buy embTCP by freertos/InterNiche? in order to get it working.

Look at the example code bundles supplied in the LPC17 subdirectory of the Examples area of your LPCXpresso installation.

You might also want to take a look at LPCOpen...
