Dear All,
Can anybody suggest me how to use printf() for debugging in this following simple code. I have used this format printf("value %d",i) but did not worked. I have heard about log_printf , bit did not able to use. Plz suggest me a suitable debugging method.
Thanks in adv.
(reader may get surprise with this code. plz dont be surprised the code has been built to perform ofdm, but unnecessary line has been deleted to make it small to post here. I believe procedure to use print which will be suggested for this code here, will work on the complex code also)
