Nano-RK Coding Conventions

• private functions shall start with _
• prefix nrk_ or _nrk_ before any Nano-RK related functions or data types
• defines and constants will have NRK_ prefixed
• all lower case separated by _ for functions
• try to avoid abrv.
• all types end with _t
• byte order is little endian
• Use C99 types:

	#include <stdint.h>
	#include <stdbool.h>
        bool		// boolean
	int8_t		
	int16_t
	int32_t		// signed int
	int64_t

	uint8_t		// as a "BYTE" value	
	uint16_t
	uint32_t	// unsigned int
	uint64_t
	
	float		// at the mercy of the compiler no hardware support
	double		// at the mercy of the compiler no hardware support
	
	void*		// instead of char* 
	char		// for text characters

• use the following gnu INDENT options:
  • indent -br -brs -nut -npsl -i2 source_name.c
• indent each level 2 more spaces than previous
• Don't put else on the same line of if

if (condition) foo (); else bar ();	/* Yuck! */

• Have the most significant description in a name first
  • For example: nrk_led_clr() and not nrk_clr_led()
