using freeRTOS vPrintString() with LPCXpresso and lpc1769 does not print anything on the console

Posted by antshiv on February 13, 2014

I am using LPC1769 and trying to test freeRTOS using its vPrintString() function but i am unable to see anything outputted on to the console. I am not sure how it works internally, and how exactly the string is passed back to the host computer but any help as to how to get this working using this setup -> LPCxpresso + lpc1769 + FreeRTPS.

Where is vPrintString() supposed output its characters? A UART?

Its supposed to output it on the LPCXpresso IDE console. I am not sure how the actual vPrintString works under the hood. Either it sends the message back to the host machine using UART or I am not sure how.

Step into the function in LPCXpresso and see what it calls, or what it does. If I know what it is doing I might be able to help.
