questions about CCS variables

[Dune]

Hi all,

I´ll really appreciate than somebody help with this questions:

1-what´s the difference between int8 and byte.
2-is there any built in function that convert to hex form (in fact, I´ll use a procedure that deals with hex, however my variables are bytes, what should I do ?)
3-I sent an integer using bputc() and receive it with bputc(), what is its received type?

BYTE is defined as int alias (which by default means int8) in CCS C header files. In case insensitive mode, you can also write byte. In other words, int8 and byte are identical.

I don't understand what you mean with hex form. Hex, in my understanding is one of several formats that can be used to print (read and write) numbers. You usually generate hex representation by printf() respectively sprintf() function. putc() simply sends one character to the interface. bputc() acually isn't a standard function rather than a function name used in a particular CCS programming example.

Sometimes two-digit numbers are BCD-coded to a byte, e.g. when interfacing real time clocks. In this case, the hex printout of the byte is identical to the coded number, e.g. 0x11 means 11th hour.

hi FvM,

thank you for answers,

to clarify my second question:

suppose this code:

Yes, exactly the same. So is
