When I try to print data such as '0x16', the display shows '0x1600'. I then tried to print 0x16 in decimal and the output is 5632, which is the decimal equivalent of 0x1600. I am using a trial version of MicroVision. Does anyone know why I am having this problem and how I could fix it?
One common problem: what's the printf() format string? Because the 8051 is an 8-bit processor, Keil C51 does not, by default, do "integer promotion" for byte-sized variables when passed as parameters. Accordingly, printf() has a new length modifier to indicate 8-bit values, e.g "%bx" or "%bu" instead of "%x" and "%u". The latter two imply 16-bit values, the former 8-bit values. printf() is a variable-argument-length routine, and so the only way it has to know the size of the argument is the format specifiers. If you pass 8 bits to printf() but use a 16-bit format specifier, the routine will try to print 2 bytes, and you'll get unexpected answers.
Thanks Drew! Your suggestion really helped us a lot. My team partner and I have spent way too much time trying to figure out that problem. Also, thanks Dave for replying to my post!
