CCS C Compiler Manual PCB / PCM / PCH

Built-in Functions
Parameters:
String is a constant string or an array of characters null terminated.
Values is a list of variables separated by commas, fname is a function name to
be used for outputting (default is putc is none is specified.
Stream is a stream identifier (a constant byte). Note that format specifies do
not work in ram band strings.
Returns:
Function:
undefined
Outputs a string of characters to either the standard RS-232 pins (first two
forms) or to a specified function. Formatting is in accordance with the string
argument. When variables are used this string must be a constant. The %
character is used within the string to indicate a variable value is to be formatted
and output. Longs in the printf may be 16 or 32 bit. A %% will output a single
%. Formatting rules for the % follows.
See the Expressions > Constants and Trigraph sections of this manual for
other escape character that may be part of the string.
If fprintf() is used then the specified stream is used where printf() defaults to
STDOUT (the last USE RS232).
Format:
The format takes the generic form %nt. n is optional and may be 1-9 to specify
how many characters are to be outputted, or 01-09 to indicate leading zeros, or
1.1 to 9.9 for floating point and %w output. t is the type and may be one of the
following:
c Character
s String or character
u Unsigned int
d Signed int
Lu Long unsigned int
Ld Long signed int
x Hex int (lower case)
X Hex int (upper case)
Lx Hex long int (lower case)
LX Hex long int (upper case)
f Float with truncated decimal
g Float with rounded decimal
e
w
Float in exponential format
Unsigned int with decimal place inserted.
Specify two numbers for n. The first is a
total field width. The second is the desired
number of decimal places.
Example formats:
Specifier Value=0x12 Value=0xfe
%03u 018 254
%u 18 254
