IÂ'm trying to use serial port in MCB2900 with LPC2919 processor and I couldnÂ't make scanf function to receive data from PC. Is there some code there for my target? IÂ'm looking for it but i havenÂ't seen anything
And what was the consensus about whether scanf was a good thing to use...?
eg, see the 1st reply in this thread: http://www.keil.com/forum/docs/thread7600.asp
Yes, i have made the scanf code search and i found some, but any code about LPC2919. I have found another processors code with scanf function. I think i have to modify retarget.c file to use scanf. I follow the others target code but in my case does not work.
But can you do it without scanf?
Obviously, if the basic serial reception isn't working, then nothing higher up the chain - like scanf - can possibly work!
And, again, scanf has a whole pile of issues all of its own - have you done that search yet?
Printf is ok, but i am trying to receive data from PC and i couldnÂ't with scanf
scanf is a standard 'C' library function - so any 'C' textbook will do!
Also search the forum for "scanf" for the many previous discussions...
But, again, have you tested your basic serial IO before moving on to scanf - or anything else?
Nothing about scanf functions sorry
Oh, come on: nothing - you can't be serious?
What about these: http://www.keil.com/support/man/docs/mcb2900/mcb2900_examples.htm ?
If that's not what you want, then don't just say, "i haven't seen anything" - say what, precisely, it is that you've found so far, and why that doesn't meet your requirements. Otherwise, you won't be taken seriously.
Hint: before messing with scanf (which has many well-known "issues"), are you sure that your basic RS232 transmit and receive codes are working?
