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
Considering that 1. C51 passes parameters in fixed memory locations, and 2. C51 stores multibyte values in big-endian order (high-order byte first) If
unsigned int i; printf("%x \n",i);
Memory addressing problem?? I don't know. I didn't mentioned but I allways modify the hex file before I download it. The reason is there are a strange line in the hex record. 03000002xxxx it'means c51 put a jump instruction to start routin at location 0. Because my system has no writeable RAM at 0 it can't download the program. So I change that line 03400002xxxxxxx which means load the jump instruction at the first read/witeable location. Everithing is in the correct address att the hex file and I do not change the others so I don't think that I made the memory addressing problem. What is your oppinion? I tried to work with Keil monitor51 but it also has some problem. I put ask to the list but I have no answer yet. Can you give me an advice where can I find good and working downloader or simple simulator program. Cheer George
