printf

hex printing
These functions allow you to print data that might contain non-printable characters. The output is in the standard hex output format, with hex representation on the left, and characters to the right. include "hex_output.h"
#define	print_hexdump(buffer, size)   print_hexdump_ex(buffer, size, 16)
	print a hexdump of buffer. This function prints 16 characters per line.
void	print_hexdump_ex (const char *buffer, uint16_t size, uint16_t line_length)
	print a hexdump of a buffer.
printf
The printf function is similiar to the printf() function used in regular C programming, except that in this case the output is sent over the UART, meaning it is readable on a PC or other connected device. This implementation does not support all formatting and has a few differences from the standard C function: use %C for 8-bit numbers. Example output: 255 use %d for 16-bit numbers. Example output: 65535 use %l for 32-bit numbers. Example output: 4294967295 use %c for characters. Example output: a use %s for strings. Example output: hello world! use %b for binary. Example output: 00110001 use %o for octal. Example output: 31 use %h for hexadecimal. Example output: 3f use %x for hexadecimal. Example output: 0x3f padding and minumum width modifiers are supported. Example output: 00012 See src/apps/printf/test_printf.c for more examples. Note: All numeric types are unsigned. printf does not support negative signed numbers.
int	puts (const char *msg)
	print a non-formatted string.
int	putchar (int character)
	print a single character.
int	printf (const char *format,...)
	print a formatted string.

Function Documentation

void print_hexdump_ex (  const char *  buffer, uint16_t  size, uint16_t  line_length )

Parameters: buffer  a pointer to an array of bytes to print. size  the number of bytes to print. line_length  the number of characters to print on each line.

int printf (  const char *  format,   ... )

Parameters: format  the format string specifying what arguments are included and how to display them. ...  any arguments referenced in the format string. Returns: 0 on success, -1 if the format string is NULL.

int putchar (  int  character  )

Parameters: character  the character to print. Returns: 0

int puts (  const char *  msg  )

Parameters: msg  the string to print. Returns: 0
