Hello, I want to ask a little bit help. I want to use the printf instruction with the Noice debugger. I can printf char or float fine but when I try to printf int or long I get a totally different numbers throu the serial port. eg. WORKS void main (void) { unsigned char f; for (f=0;f<=255;++f) printf( %bu \n",f); } but DOESN'T WORK void main (void) { unsigned int f; for (f=0;f<=255;++f) printf( %u \n",f); } Thanks for any advice Cheer George
This is an old chestnut! It is very important that the argument types must match precisely the types specified in the format string. Read the section Problems Using the printf Routines in the C51 manual, and see the table of format characters in the description of printf. In particular, note that %d and %u are for ints; for chars you must: either use the b prefix; or cast your char to an int
