Recently i heard about printing o/p from target MCU to the Console in IDE while debugging. I have tried a lot googling but still I cant implement it. I have an LPC Xpresso kit with LPC 1114 MCU. IDE version v3.6.3.

Look for 'semihosting' and 'printf'

Try:

It suddenly started working. I am using printf() and putchar() functions. Is that correct?

If it's printing to your Console, it's obvious working :)

If you use the project wizard to create a "Semihosting C project" everything will be set up so that the printf will write "Hello World" out to the console of the IDE for you.

For more information see the C library FAQs....

Using printf() suddenly increases the file size from 6k to 18k. Is there any way to reduce that? I have already selected Redlib (semihost) in the project properties.

Did you read the FAQ?

To enable the non-floating-point printf from Redlib, define the symbol "CR_INTEGER_PRINTF".
