I am writing some serial data transfer apllication, i was seeing some examples given by keil. in that hello world example i have seen. i that they have used printf function which will print in serial window.... there if i am using printf("%x",variable say 'a');there it is appeding a zero at the end of variable. please clarify y it is happening so?
It does not happen, how will it print without a '0' put in there,
"It does not happen"
How can you possibly say that? You haven't seen his code - there could very possibly be something in there that causes it!
